Six on Saturday: More Unexpected Surprises

Several of these Six were featured here before, and some only recently. They continue to surprise.

1. Musa ingens, oem, or giant highland banana, produced two pups. This is the larger of the two. Although I was told that this is oem, I am not certain. It behaves like the species in some ways, but not others. For example, oem should only occasionally produce pups.

2. Heuchera sanguinea, coral bells does not look coral to me. This looks like simple red. I think of coral as more orangish pink. Is that correct? I can not complain, since I prefer this color. Some of the fancy foliar cultivars here bloom with colors other than coral too.

3. Canna X generalis ‘Cannova Mango’ canna and feral Antirrhinum majus, snapdragon that I posted pictures of two weeks ago are blooming even better together now. Why are some of the best flowers as unplanned as these were? Perhaps I should unplan for more.

4. Helenium autumnale, tickseed was yellow last week. This is literally the same flower. Is this new color orange or red? Was it supposed to be this color, or is this what happens to yellow flowers as they fade? I will need to see how the other two varieties bloom later.

5. Passiflora caerulea ‘Constance Elliott’ passion flower smells like pineapple guava, but only briefly. Its fragrance is gone before I can get someone else to confirm the similarity. The garishness of this bloom does not last very long either. This flower is wilted by now.

6. Rhody rarely cooperates for pictures. He should though, since he is who we all want to see here for Six on Saturday. I would post six pictures of him weekly if he would allow it. Perhaps I should have gotten a picture of Heather too. She cooperates more for pictures.

Angel’s Trumpet

Angel’s trumpet impresses with huge flowers.

Lineage can be difficult to identify. Most popular cultivars of angel’s trumpet, Brugmansia are hybrids. Many are hybrids of hybrids. Almost all are consequently identifiable by only their genus and cultivar names. They usually lack species names. Their original species were likely native from Venezuela to Chile or southern Brazil. No one knows definitively.

Angel’s trumpet is a big bushy perennial. Its trunks may be as substantial and persistent as those of small trees. Most popular cultivars can grow higher than eight feet. A few rare cultivars should grow larger. Leaves are about six inches long and half as wide, or larger on vigorous stems. Some cultivars have slightly tomentous foliage. A few are variegated.

Bloom is sporadic while the weather is warm, and can be profuse in phases. Flowers are commonly longer than six inches and wider than three. Most are very pendulous. Double flowers are quite frilly. The floral color range includes pastel hues of yellow, orange, pink and white. Several cultivars are nicely fragrant. All parts of angel’s trumpet are toxic.

Fragrant Bloom Appeals To Pollinators

Fragrant bloom needs no bright color.

Aroma and fragrance in a garden have two very different natural purposes. Aroma, which is foliar, repels insects or animals who may otherwise eat such foliage. Fragrance, which is floral, attracts insects and animals to pollinate such flowers. Aromatic foliage ironically appeals to people, particularly as herbs. The appeal of fragrant bloom is not so contrary.

With few exceptions, fragrant bloom is an asset to a garden. Although its primary function is to attract pollinators, people enjoy it also. The few exceptions are flowers that produce fragrances that are unappealing to people. For example, several species of Arum attract flies for pollination. Therefore, they exude foul fragrances that appeal specifically to flies.

Fortunately, most pollinators prefer fragrances that people also enjoy. Many of the richest and strongest fragrances appeal to a broad range of pollinators. Some more refined and distinctive fragrances attract specific pollinators. Fragrant bloom is most fragrant when its preferable pollinators are most active. A few bloom at night for their nocturnal pollinators.

Fragrant bloom is generally not as colorful as bloom that is less fragrant. It does not need to be. Color is merely another visual means with which to attract pollinators. Flowers that are both fragrant and colorful are mostly from competitive ecosystems. Angel’s trumpet is both spectacular in bloom and splendidly fragrant. Yet, its floral color is limited to pastels.

Some of the most fragrant bloom is that of bulbs that bloomed early last spring. Hyacinth, narcissus, freesia, lily and some bearded iris are both fragrant and colorful. Wisteria and pink jasmine are vines that were also fragrant and colorful last spring. Star jasmine is not quite as colorful, but is as fragrant, and still continues to bloom. So does angel’s trumpet.

Warming summer weather will now promote more fragrant bloom, even if it is not colorful. Pittosporum undulatum exudes an almost citrusy fragrance. Pittosporum tobira is slightly buttery. Sweet osmanthus and sweet box are proportionately more fragrant while young. Night blooming jasmine might be the sweetest of all, but more so during warm evenings.

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.

Six on Saturday: Not Yet Summer Bloom

Too much is blooming now for pictures of foliage, bark, trees, vines, shrubs or any other horticultural subject matter. I got these pictures before yesterday, so they are technically still spring bloom.

1. Gladiolus X hortulanus, gladiolus looks silly alone. It was the first to bloom. All others are in small colonies that developed from reliably perennial bulbs, which were originally components of a mixed batch. I would not have expected any to be so reliably perennial.

2. Lavandula angustifolia, English lavender has similarly lasted longer than expected. It was already a few years old several years ago, when I predicted its natural demise within two years. A feral specimen of Spanish lavender coincidentally grew from a seed nearby.

3. Antirrhinum majus, snapdragon is also feral. All within its colony bloom white. Those of another feral colony all bloom yellow. However, the parents of both colonies bloomed with mixed colors of the same variety. I can not complain, but I wonder what happened.

4. Celosia argentea, plumed cockscomb blooms with these red, orange or yellow flames. The chartreuse foliage in the background is coleus. They are a good example of why I do not procure annuals at work. I have difficulty with such striking color, texture and form.

5. Abutilon X hybridum, Chinese lantern is an awkwardly lanky shrub that will not stop blooming. I would like to prune it down to perhaps improve its density, but do not want to interfere with its bloom schedule. It has been here for many years, and might be feral.

6. Canna ‘Cannova Mango’ canna is not my favorite cultivar, but has too many attributes to discredit. It begins blooming before any other canna here. It blooms more abundantly than any other canna here. I know of no one else who dislikes this color as much as I do.

Six on Saturday: Making Up For Lost Time

A few late bloomers are making up for lost time. Hydrangea, although late, is somewhat earlier than it typically is. Bluegum is not blooming, but contributes its own sort of color with bark.

1. Eucalyptus globulus, bluegum remains canned because it grows too big too vigorously to go into the ground. Ultimately, it will likely need to be destroyed. For now, it provides both aromatic juvenile foliage and pretty adult foliage. It also has pretty watercolor bark.

2. Yucca recurvifolia, curve leaf yucca is known as Yucca gloriosa var. tristis now. What was wrong with its former botanical name? Its boring common name should be changed instead. Anyway, I am impressed that it is blooming so soon after relocation last winter.

3. Hibbertia scandens, guinea gold vine grew like a weed from a cutting last year, and is now beginning to bloom for the first time. This is the first of many flower buds to unfurl. Its bloom was expected, but its profusion is unexpectedly impressive. It remains canned.

4. Hemerocallis fulva, daylily was similarly expected to bloom and is similarly blooming with unexpected profusion. I have no idea what cultivar this is, but I suspect that it may be the straight species. We grow just one other daylily cultivar, and it is relatively docile.

5. Begonia semperflorens-cultorum, wax begonia had languished for years in its planter box full of aggressive redwood roots. It now grows much more happily in its new planter box within its old planter box, which is elevated on cinder blocks above an empty space.

6. Hydrangea macrophylla, hydrangea typically blooms later on axillary stems because I prune the terminal buds off with winter dormant pruning. My concern was that, if I left the canes intact as I should, they would flop over. They are flopping, but it was worth it.

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!
