White Flowers Attract Pollinators Also

Phlox happens to excel at white.

Floral color attracts pollinators. Hummingbirds mostly prefer bright red, pink and orange. Butterflies mostly prefer bright orange and yellow. Bees prefer bright blue and purple, but are less discriminating than other pollinators. Of course, these are mere generalizations. Otherwise, the majority of pollinators might ignore species that bloom with white flowers.

Realistically, most flowers do not rely on pollinators for pollination. They rely exclusively on wind, so are just green or brown, and not visually prominent. These include flowers of grasses and conifers. Otherwise, small but prominently prolific white flowers are the next best option. They rely on either or both wind and pollinators for very effective pollination.

For example, firethorn bloom is very appealing to bees and other pollinators. It is also so prolific that some of its pollen disperses into the wind. Its tiny but abundant white flowers can not avoid pollination by one means or the other. Most orchard trees, such as apricot, plum, apple and pear, use the same technique. So do viburnum, photinia and elderberry.

This should not imply that white is a substandard color, though. After all, white flowers do attract pollinators. Several pollinators, such as nocturnal moths, prefer luminescent white flowers. More importantly, many pollinators see more than white. Several types of Insects see ultraviolet. What seems to be white to us can actually be elaborately colorful to them.

Furthermore, white needs no justification. It happens to be the best color option for some garden applications. It brightens visually dark situations, and mingles well with almost all other colors. A few types of flowers, particularly those with distinctive form, excel at white. Calla, camellia, lily of the valley and various lilies are only a few of numerous examples.

Cool season annuals for autumn and winter will soon replace old warm season annuals. White busy Lizzie, petunia, cosmos, alyssum, snapdragon and zinnia are finishing soon. White pansy, viola, dianthus and wax begonia may replace them. Later in autumn, white cyclamen will become seasonal. There are always enough white flowers to choose from.

Color Selection

There are not many colors that bearded iris can not provide.

If I could select my favorite color for the flowers in the garden, they would all bloom white. There is no more perfect color. White may be bright or pale, but lacks the many shades that other colors have. There is no need to select between deep blue or sky blue, bright yellow or pastel yellow, purple or lavender. White is simply white.

The main problem with white, or any other color, is that no color is the right color for every situation. Also, some flowers are simply not at their best in white. Camellias, oleanders and fruit trees look great in white. However, nearly white marigolds, sunflowers and nasturtiums are interesting oddities that are excellent in the right spot, but are not nearly as flashy as the more traditional bright yellow and orange shades are.

My two favorite geraniums are actually reddish orange and fuchsia pink, and really look horrid in bloom together. They are my favorites nonetheless, because I have been growing them since my sophomore year at Prospect High School! I have taken cuttings with me whenever I relocated since then. I enjoy the garden too much to grow things that I do not enjoy.

Flower colors probably should be compatible with the colors and architecture of associated residences and other buildings, as well as the neighborhood. Yet, we all have different tastes. It is more important to grow flowers with the colors that we enjoy, even if they are not exactly perfect for their particular situations. Fortunately, compatible colors are more likely to also be enjoyable.

White happens to be useful in shaded areas, or with an abundance of deep green, such as wax privet hedges. White brightens an area, even in conjunction with other colors. It also softens richer colors like purple or red.

Darker shades of purple, red and blue should be out in the open, since they can make shaded areas seem even darker. Lighter shades, including lavender and pink, can work almost anywhere. True blue happens to be uncommon among flowers, even though the very common lily of the Nile is typically blue.

Yellow and orange seem at home in sunny spots, and also brighten shaded spots if not overdone. Yellow contrasts with purple. Orange contrasts with blue. Orange marigolds and cobalt blue lobelia might look odd in abundance, but can be striking as a border to a perennial or annual bed. Many of us like a random mix of any color; but too much mix over a large area can look like a garage sale of colors. Black, gray and brown flowers are rare and mostly grown by those of us who really appreciate them; since they look quite odd in the wrong situations. Black hollyhock, pansy and bearded iris are perhaps the best blacks, while other black flowers are not so convincing. Gray iris are still quite rare. Brown sunflowers are becoming more popular.

Chameleon

What color is this? It looks pink to me. A day earlier, though, it looked peachy orange. At various times last year and the year earlier, this same angel’s trumped bloomed more orangish orange, yellow and even white. I can not remember its schedule now, but I know that it has been weirdly variable. It is one of four cultivars of angel’s trumpet here, but the only one that will not decide on a color for its bloom.

One of the other four angel’s trumpets here blooms with double white flowers. My favorite, although relatively diminutive, blooms with single white flowers. The most vigorous is ‘Charles Grimaldi’, which blooms with single yellow flowers. A formerly fifth cultivar with big single pink flowers unfortunately rotted without replacements over winter a few years ago.

This particular angel’s trumpet grew from scrap that I took from a green waste pile at the curb of a job site in eastern San Jose several years ago. I took it because I found the pastel orange foliar color of the specimen that it was likely pruned from to be appealing. I had no idea that it would bloom with so many other comparably appealing floral colors.

More White Trash

White is my favorite color. It is not the best color for all flowers, but it is the only color that I allow within the White Garden, which is really just the meager landscape of the Mount Hermon Memorial Chapel. Creamy white, such as white nasturtium and white canna, are not white enough. I am adamant about this. After replacing a few blue lily of the Nile with a white hydrangea, I needed to remove the hydrangea as it began to bloom with a slight pinkish blush. About that time, two winters ago, we added a white climbing rose. It was a perfect fit, and produced a straight cane that extended from the top of an original cane to the eave during its first summer. Because it was still young and small, it bloomed mildly but sufficiently. More importantly, it bloomed white. It got pruned over winter. Now that it is a bit larger, it is blooming a bit more fuller. However, it no longer seems to be blooming pure white! Young flowers unfurl with a creamy pale yellow blush before fading to white. It is too pretty to remove, especially without a replacement. This could become a major dilemma!

White on Wednesday

Syringa vulgaris ‘Madame LeMoine’ French hybrid lilac bloomed bright white and right on time as March became April, and is not finished yet. It was somewhat of a surprise, since it remains canned until development of the landscape that it should eventually inhabit. It does not grow much while canned, so was not expected to be so spectacular in bloom. It is so spectacular that it was temporarily placed into a prominent position within another landscape, with its can mostly obscured by other vegetation, until it finishes bloom.

However, regardless of how spectacular it is, it reminds me that white is not necessarily the best color for all flowers. White happens to be my favorite color, and lilac happens to be among my favorite early spring flowers, but to me, lilac bloom should be lilac colored. I mean, it really should be that lavender or pastel purple color of traditional and formerly common old fashioned lilacs. The only advantage to this white floral color is that it would be appropriate to situations in which white is the most desirable color, or where lavender is undesirable.

Just as many flowers are at their best in white, some are best with other colors. Southern magnolia, lily of the valley, moonflower, gardenia, Easter lily and old fashioned calla are exclusively white, and would look weird in any other color. Gladiolus, tulip, hyacinth and rose can be all sorts of colors, but happen to excel at white. A few other flowers that can be all sorts of colors happen to not excel at white, such as bougainvillea, crape myrtle, English primrose, tropical hibiscus, wisteria and, of course, lilac. Both white crape myrtle and white bougainvillea happen to have been selected specifically for landscapes here, so perhaps white lilac is not so out of place.

Pollinators Are As Busy As Bees

Flower breeding is not for pollinators.

Flowers bloom for pollination. It is that simple. Most rely on wind to disperse their pollen. They are more abundant than colorful or fragrant. More prominently colorful and fragrant flowers rely on pollinators. Their color and fragrance attract preferred pollinators, such as insects, birds or bats. Such flowers sustain their pollinators with nectar or surplus pollen.

More than pollinators appreciate their diligence. Almost everyone who enjoys gardening enjoys floral color and fragrance. Cultivation of naturally appealing bloom began several thousand years ago. Selection and breeding most likely began relatively soon afterward. Ultimately, during relatively modern history, hybridization began getting too complicated.

Pollinators were not a priority during such processes. Because most ornamental flowers produce no usable fruit, pollinators are unimportant. Because of extensive hybridization, many ornamental flowers are sterile anyway. Floral color, fragrance and various tangible attributes are more important. Modern bloom appeals more to people than to pollinators.

A few modern flowers now confound their original pollinators. Some types of insects can die of exhaustion while trying to ascertain them. These insects may recognize floral color or fragrance but not strange floral structure. A few modern flowers are too frilly for access. Some attract pollinators without providing enough nectar or extra pollen to sustain them.

Several exotic flowers with less or no breeding distract pollinators with their abundance. Lemon bottlebrush blooms very abundantly and is still common within some landscapes. Blue gum eucalyptus is naturalized in parts of California. Both attract monarch butterflies that native species rely on. Native ceanothus must instead rely more on other pollinators.

Furthermore, a few pollinators actually disrupt native ecosystems. Honey bees, although very important to local agriculture, are not native. They arrived in San Jose in 1853, from where they dispersed throughout the West. It is now impossible to assess their influence. Even seemingly beneficial influence is unnatural and therefore ecologically detrimental.

Six on Saturday: P III

P was about a white blooming perennial pea, Lathyrus latifolius, that I recently found to replace what I inadvertently lost earlier. P II was irrelevant to both that and this, but did happen to get a title that incorrectly designates it as a sequel to P, and prevents me from using that title for this Six on Saturday post with three variants of perennial pea and the more typical sort. Perhaps I should not have expended such effort for such a weed. What is worse is that I canned and am now growing copies of the three variants as well as the favored white blooming variant.

1. Canna are irrelevant to the primary topic, but are too cool to not mention. These were placed here temporarily in random pots until a new landscape gets installed next winter.

2. Canna musifolia dominates, which is why there is not much bloom. This one stands a bit more than eight feet high in its pot. It might be ‘Omega’ like the compact Oldsmobile.

3. Lathyrus latifolius, perennial pea is the primary topic because I found three variants. This one blooms with swirled pink flowers. It is about as rare as those that bloom white.

4. This looks white in this picture but is actually blushed very slightly with pink. I should have gotten a better picture. I dug and canned a copy because I had never seen it before.

5. This is the typical floral color of the species. To me, it looks purplish pink. I am not so proficient with color. Others say it is pinkish purple. It justifies my preference for white.

6. Like the picture of the very slightly blushed white flowers, this is not a good picture of flowers that seem to be slightly richer purple than the typical purplish pink. I got a copy.

Six on Saturday: Homey

Almost nothing is purchased for my garden. Not much more is purchased for work. Just about everything is recycled from somewhere else, along with its history. Consequently, the landscapes are as homey as my home garden is. It is often difficult to not brag about it a bit too much. It is gratifying that others can enjoy so much of what I have enjoyed in my garden. For Six on Saturday, though, I will be brief with my descriptions of these few flowers that bloomed last week. Half are angel’s trumpets. Half are white. Of course, it is no coincidence that white is my favorite color. I requested pruning scraps of single white angel’s trumpet and white orchid cactus. Even if recycling, I may be somewhat selective. It all works out well.

1. Gladiolus papilio, butterfly gladiolus that was budded last week bloomed this week. It makes its landscape feel delightfully homey for me. I should have gotten a better picture.

2. Hydrangea macrophylla, bigleaf hydrangea, like so much of what blooms here, came from another garden, then bloomed too well in recovery to not move out to a landscape.

3. Brugmansia, angel’s trumpet of an unidentified cultivar remains unidentified, but is a bit more obviously pink than any other color. Perhaps its cultivar name is not important.

4. Brugmansia candida, angel’s trumpet with fluffy double white flowers is what started all this fuss about angel’s trumpet. Yellow ‘Charles Grimaldi’ was the second acquisition.

5. Brugmansia, angel’s trumpet with single white flowers is an unidentified cultivar that I got merely because I like its single white flowers, but is not so great for the landscapes.

6. Epiphyllum, orchid cactus with clear white flowers remains as unidentified as most of these Six. Like all of these six, it also has important history that makes its garden homey.

Floral Color Communicates To Pollinators

Flowers attract their pollinators with color.

Bloom is bountiful for spring. It is more abundant now than it will be at any other time of year. Early bloom has more time to produce more seed prior to autumn and winter. Also, it can most efficiently exploit its pollinators who are also most active in spring. The most prominent blooms appeal to such pollinators with floral color. Their effort is remarkable.

Most bloom within most natural ecosystems here relies on wind for pollination. Although very efficient, it lacks prominence. Some grasses seem to produce seed without evident bloom. Because such vegetation does not rely on pollinators, it has no need to advertise. Toyon produces tiny but prominently profuse flowers for both wind and insect pollination.

Most species within home gardens rely on pollinators rather than wind for pollination. At least their ancestors did. They originally developed both floral color and floral fragrance to attract pollinators. Extensive breeding enhanced color and fragrance, but also caused sterility for some. Others are not true to type. Their visual appeal became less practical.

Obviously, such visual appeal and associated practicality are subjective. Although less practical for procreation, enhanced bloom is more practical for home gardens. Most who enjoy flowers appreciate enhanced floral color and enhanced floral fragrance. They are unconcerned with how species that provide such bloom procreate. Looks are everything.

Besides, some pollinators can still enjoy most enhanced floral color. A few flowers are so genetically modified that they confuse some pollinators. A few insects die of exhaustion while trying to gain entry. Generally though, most get what they came for or safely leave without it. Many who enjoy gardening also enjoy pollinating insects and hummingbirds.

Ultimately, floral color is personal. Many garden enthusiasts prefer specific color ranges or specific colors. Many prefer an abundance of color. Some prefer more subdued floral color. Some prefer specific types of flowers to provide floral color. Bloom season may be another concern. Some want more winter bloom while nearby gardens lack floral color. Many prefer major spring bloom. Some like random bloom through the year.

Cool Season Color Returns Seasonally

Pansies and violas like cool weather.

Cool season vegetables are the first clue. Now that they are seasonal, cool season color is also seasonal. Both comply with similar schedules. Their cool season centers around winter, including portions of spring and autumn. Some prefer to start early. Some prefer a later start. They also finish at variable times through spring. Some perform until summer.

Warm season color also complies with distinct schedules. Some might finish a bit earlier than their cool season replacements begin. Conversely, some could continue to perform a bit later than their replacement allows. It is gratifying when color of one season finishes as color of the next season begins. That will become more likely later within the season.

Cool season color has a few designations. Winter commonly replaces cool season. Yet, it includes adjacent portions of autumn and spring. Bedding plants or annuals commonly replaces color. Yet, many are actually perennials, and none are limited to bedding. Large homogenous beds are passe anyway. Some perennials linger after their primary season.

Also, some species behave differently here than within other climates. Wax begonias are warm season color, but may dislike locally arid warmth. They perform better for spring or autumn than for summer here. Actually, they become as popular as summer ends as they are when winter ends. They bloom until frost, or continually and perennially without frost.

Growth is slower during cool weather. Therefore, seed for cool season color should start early. For most, small plants, such as those from cell packs, are more efficient than seed. Cyclamen grow so slowly that they are only available in expensive four inch pots. Some cool season color is better for autumn or spring. This includes marigold and snapdragon.

Pansy and viola are the most popular of cool season color. Pansy are a type of viola with fewer but bigger flowers. Various types of primrose are nearly as popular, and can bloom until summer heat. Iceland poppy can grow a bit later in autumn to bloom through winter. Sweet William is a perennial that blooms now until spring, and can resume next autumn. Ornamental cabbage is bold foliar cool season color.
