Six on Saturday: Gazania

 

Gazanias were not planned. The English daisies that were planted last spring as warm season annuals that might hopefully continue as perennials succumbed to rust. Seriously! This rust was nasty! I had no idea that English daisy was so susceptible to rust! They were so ugly that they needed to be removed. They were replaced with the gazanias a bit more than half way through.

Gazanias are not the flashiest of choices for the prominent planters that they went into, but they work. If they continue to bloom through winter, they can stay as long as they like. If they stay long enough to get bald spots, we can trim around the edges and plug the scraps back into the bald spots. I would rather put a bit of effort into maintaining them than replace them as the seasons change.

These pictures were taken about two weeks ago, along with the picture of the gazania that was posted last week. For some unknown reason, the gazanias are presently taking a break from blooming.

1. White is actually not my favorite color for gazanias. Yes, white is my favorite color. I just think that gazanias are at their best in brighter colors like yellow and orange. This white is not the best anyway. It looks like very pale yellow to me.P80922

2. Yellow, in conjunction with orange, is one of the two classic colors for gazanias, and is one of my two favorites . . . in conjunction with orange.P80922+

3. Orange is the other half of the caption to the picture above. (Just read the same caption, and switch ‘yellow’ for ‘orange’, and ‘orange’ for ‘yellow’.)P80922++

4. Pink might really be light burgundy. It was a bit darker when it first bloomed. This might be one of those colors that only girls can identify.P80922+++

5. Yellow with red stripes looks like something that blooms in the garden of Ronald McDonald.P80922++++

6. Cream with burgundy stripes looks like something that blooms in the garden of a clown with slightly more discriminating taste.P80922+++++

Cosmos

80905Their pastel hues and blends of pink, lavender, near red and white are so perfect for the middle of spring when cosmos, Cosmos bipinnatus, begin to bloom. They are just as perfect as bloom continues right through summer and almost to autumn, when the tall and airy plants finally begin to wear themselves out. If they continue through autumn, they eventually succumb to frost in winter.

Individual flowers are as delicate as they look, but are prolific. New flowers replace older flowers a quickly as they fade. Deadheading promotes even better bloom. A few of the last flowers to bloom can be left as the season ends to sow seed for next year. However, fancy cultivars are not true to type, so subsequent generations will be more like the basic specie, with simpler flowers.

Cosmos likes full sun exposure, rich soil and regular watering. Mature plants are about two or three, or even four feet tall, although the most popular varieties stay shorter and more compact. The species name of ‘bipinnatus‘ refers to the pinnate leaves that are divided into very narrow lobes that are also divided into even narrower lobes. The collective foliage is very delicate, lacy and airy.

New Guinea Impatiens

70802Good old fashioned busy Lizzie is hard to find nowadays, if it can be found at all. The nasty mildew that kills it so quickly might not be prevalent everywhere, but happens to be a serious problem where most of the bedding plant farms are located. Now, the formerly uncommon New Guinea impatiens, Impatiens X hawkeri, which is somehow resistant to the mildew, is becoming popular.

The two specie have distinct personalities though. Busy Lizzie dazzles with cheery cartoonish colors, and bloom profuse enough to almost obscure the light green foliage. New Guinea impatiens has bigger and bolder flowers of white, pink, red, magenta, lavender, purple, apricot and reddish orange, but does not try to hide its rich green, bronze, purplish bronze or gold variegated foliage.

New Guinea impatiens are more expensive, and are not available in cell packs like most other bedding plants are. They are most popular in four inch pots. They do well in pots and tolerate partial shade, but want rich soil and regular watering. Mature plants can get more than a foot wide, and might get as tall if crowded. Although grown as annuals, they can survive as short term perennials.

Busy Lizzie

80801In only a few years, busy Lizzie, Impatiens walleriana, went from being one of the most popular warm season annuals to being unavailable in nurseries. It is now making a slight comeback. Most of those planted during their planting season last spring are now so profuse with bloom that their rich foliage is mostly obscured. Although they can be perennial, almost all get replaced in autumn.

The problem associated with their unavailability was that a type of downy mildew that is resistant to common fungicides had become a temporary epidemic among the growers who supply the plants. The disease is still out and about, so can still infect busy Lizzie, but is not such an epidemic after a few years of scarcity of host material for it to infest. Nonetheless, busy Lizzie is still risky.

Bloom is clear and cheery hues of pink, red, magenta, peachy orange, pale lavender and white. The five petaled flowers are about an inch or two in diameter. Leaves are a bit bigger than the flowers. Foliage and stems are succulent and very fragile, so will not tolerate traffic, and will die in winter if exposed to frost. The biggest plants can get almost two feet tall and three feet broad.

Annual Gazania

80620Why would anyone want to grow annual gazania when perennial gazania that is popularly grown as ground cover lasts for several years? Well, as long as the weather stays warm, annual gazania blooms with an impressive abundance of bigger and more brightly colored flowers. Perennial gazania blooms less profusely and only in midsummer, with simpler and somewhat smaller flowers.

Flowers are warm shades of orange, red, yellow, pink, beige and white, typically with intricate patterns of stripes and spots of other colors of the same range, as well as chocolatey brown. Each upward facing daisy flower is as wide as three inches or maybe four. They close up at night and during cloudy weather, and stay closed briefly in the morning until they warm up a bit in the sunlight.

Mature plants typically do not get much more than six inched deep, but can get twice as deep if crowded. They have no problem getting nearly a foot wide though. Foliage is only slightly bronzed; not quite bronze, but not rich green either. The pretty gray undersides of the leaves are obscured from view by the density of the foliage. Gazania needs full exposure, and is quite tolerant of heat.

Six on Saturday: Petunias

 

These were only recently planted, within the past few weeks, so are not completely filled in. That of course is unimportant for pictures of only the flowers close up. I have not grown petunias for many years, but I am getting to like these because they are so colorful in the sunnier spots. There are busy Lizzy in the shadier spots. (I can explain that later.) It is not easy to select a favorite. Although the white petunia should be my favorite, I really like how brightly colorful the first one ‘Dreams Sky Blue’ is on the side of the road. ‘Blue Madness’ and ‘Red Madness’, the second and third pictures, are so reminiscent of petunias that we grew many years ago, and might even be the same. The unknown petunia in the fifth picture is the only one here that I do not like much, and it did not work out as well as hoped anyway. It is planted in hanging pots, but does not cascade. That is why a few ‘Wave Lavender’ in the fourth picture were added in with them. The white petunia happens to be only one of a mix of various colors.

The first three were planted in beds at ground level. The fourth was planted both in an elevated planting bed, and added to hanging baskets with the fifth. The fifth was the first to be planted in the hanging baskets, but is not cascading as expected. The sixth, along with a variety of other colors, is in a few large planter boxes, so will hopefully cascade somewhat, but does not need to.

Verbena

80613This is one of those warm season annuals that we do not hear much about. Verbena looks something like lantana, but rather than maturing into a nice shallow ground cover or low mounding shrub with a bit of staying power, verbena lasts only until frost next autumn. The blooms are a bit larger. The leaves are a bit greener. They stay lower than a foot, and get only a few inches wider than tall.

Floral color was already impressive decades ago when it was limited to white and rich hues of blue, red, purple and pink. Even more hues and shades are available now, as well as peach, rose, lavender and many bicolored varieties. The tiny flowers are arranged in small and dense trusses, with the outer flowers opening and fading to lighter hues before the inner flowers opening darker.

Bloom is best in full sun exposure. A bit of partial shade should not be a problem for those that cascade from planter boxes up against a wall, or pots that hang from eaves. Verbena is popularly grown as a cascading component of mixed plantings in large pots, urns and elevated planters, often in conjunction with more upright plants. Verbena works nicely for small scale bedding as well.

Snapdragon

80523They are short term annuals in spring or autumn. Where winters are cold, they may last from spring through autumn. Where summers are hot, they may last from autumn through spring. So what are snapdragon, Antirrhinum majus, here? They can be either or both, depending on where and when they get planted. For most of us, they are a cool season annuals that finish before summer.

Although they prefer to be in full sun, the warmth of such exposure is what limits their practicality through summer. They bloom a bit less in partial shade, but are more likely to last through summer if kept cool, particularly in an innately cool microclimate. Like many annuals, they want rich soil, and regular watering. Because they are susceptible to rust and mildew, foliage should be kept dry.

Snapdragon blooms in white and many cheery hues of yellow, orange, red and pink. Some of the older varieties, particularly those developed for the cut flower industry, can get very tall, and might almost reach low eaves! Modern garden varieties are shorter and fluffier. The biggest are less than four feet tall, and less than a foot and a half wide. Deteriorating flowers should be pruned away.

Pot Marigold

70405Just before the weather gets warm enough for real marigolds, and after the weather starts to get too cool and rainy for them, pot marigold, Calendula officinalis, is at its best. It can bloom at any time of year, depending on when it gets planted, but prefers cool and humid spring and autumn weather. It is not so keen on frost in winter, or the arid warmth of summer that real marigolds enjoy.

They are just as versatile as real marigolds are, and work nicely in pots, but they are known as pot marigold because of their history as culinary herbs. They also have medicinal applications, and can bu used for dye. Mature plants do not often get bigger than a foot tall and wide, with somewhat coarse light green foliage. The two or three inch wide flowers are bright yellow or orange, and can sometimes be double.

Candytuft

80321It looks like sweet alyssum, but is not even close. The tiny white flowers and finely textured foliage work almost as well for similar uses in the landscape. In fact, the plants are most often grown as short term warm season annuals. However, candytuft, Iberis sempervirens, is really a perennial that can be cut back in autumn, regenerate through winter, and bloom for spring and early summer.

One must really examine candytuft closely to see that it is related to cole crop vegetables like broccoli, cauliflower, cabbage and Brussels sprouts. That is why is has an odd aroma when cut back. Mature plants have the potential to get nearly a foot deep, but typically stay lower. They can spread a bit wider than a foot. Candytuft can tolerate a slight bit of shade, but prefers sunny exposure.

If planted closely together, candytuft can form a nice small scale ground cover. It mixes nicely with stones, and cascades slightly over the edges of low stone retaining walls. It is more substantial than sweet alyssum, and works better for permanent planting in borders and along walkways. The barely perceptible floral fragrance of individual plants can be quite appealing in larger volumes.
