Six on Saturday: Moss Rose

Moss rose has something in common with fern pine and cabbage palm. ‘It is neither this nor that’. Fern pine is neither a fern nor a pine. Cabbage palm is neither a cabbage nor a palm. Well, moss rose is neither a moss nor a rose. It is Portulaca grandiflora. It is a somewhat uncommon warm season annual that blooms until frost, with potential to toss a few seed for next year.

Ours were planted a bit late, after English daisies that were where they are now succumbed unexpectedly to rust. Because they are in three small planter boxes, where annuals get replaced regularly, they will not be able to naturalize. I suppose I could collect some of the seed to toss about nearby, or in a sunnier place where they would be happier. It really is that time of year.

These six picture show six of the colors of our moss rose. There might have been a seventh color that was very pale pink. It was omitted because it was so similar to the white that I am still not certain that it was not white. Peach #3 is more distinct from orange #4 than it seems to be in these pictures. Red, which is common among moss rose, is strangely lacking from our mix.

Flowers are somewhat variable. Pink #1 seems to be a bit fluffier than the others. Yellow #5 has a bit of red around the center. Rose #2 seems to have a very slight bit of white at the center. I only guessed on the names of the colors ‘rose’ for #2 and ‘peach’ for #3.

Moss Rose

41015The recent unseasonably warm weather was no problem for any remaining moss rose, Portulaca grandiflora. They usually start to look rather tired as the weather gets cooler this time of year, and eventually succumb to the first frost. Where allowed to do so, they can regenerate next year from seed. I like to collect their seed during the summer or autumn so that I can sow them after the last frost of the following winter. Through spring and summer, I find that additional plants are easy to grow from cuttings.

The inch wide flowers are white, pink, red, orange or yellow, with only a few ruffled petals. Modern varieties that have rufflier ‘double’ flowers and richer colors still seem to be less popular than the more delicate traditional types. The cylindrical and succulent leaves are only about an inch long. The small plants can get more than six inches deep where they are happy or crowded. Moss rose likes good exposure and decent soil, but does not need the rich soil that most other annuals demand. Nor does it necessarily need such regular watering.

Angelonia

41008Angelonia is one of those warm season annuals that can actually survive through winter as a pernnial to bloom again next spring. It may even want to continue to bloom untill frost. The flowers can be blue, purple, red, pink or white, and look something like small snapdragon flowers. Most have spots or stripes of an alternate color or two in their throats. Some modern varieties have fragrant flowers. Plants can get a foot or two tall, and almost as wide. In sheltered spots, angelonia can be cut back as soon as it starts to look tired in autumn. Exposed plants might be happier if cut back significantly later, as winter ends. Old growth may be unsightly for a while, but can protect interior stems and roots from frost. Besides, pruning stimulates new growth that will be more susceptible to subsequent frost.

October Brings Cool Season Annuals

41008thumbAs the name implies, ‘annuals’ need to be replaced ‘annually’. What is worse is that they do not even function for an entire year, but only for a specific season. Cool season annuals mostly work from autumn to spring. Warm season annuals mostly work from spring to autumn. Calendula is a popular cool season annual that may not last even that long, since it can mildew half way through winter.

Now that it is time for cool season annuals, it can be unpleasant to remove warm season annuals that are still performing well. In mixed plantings, new annuals can be phased in through autumn as older annuals deteriorate. Busy Lizzie (impatiens), wax begonia and other warm season annuals that are actually perennials can get cut back and overplanted with cool season annuals. The cool season annuals that temporarily overwhelm them can provide shelter from frost. As the cool season annuals finish next spring, the warm season ‘annuals’ can regenerate

However, not all cool season annuals need to finish next spring. Sweet William, cyclamen, chrysanthemum and the various primroses are popular cool season annals that are actually perennials. When the time comes, they can be overplanted with warm season annuals, so that they can regenerate the following autumn. In cool spots, sweet William and some primroses can actually perform all year. (Some people are allergic to primroses like poison oak.)

Alyssum and nasturtium really are annuals, but can function both as warm season and cool season annuals. They sow their own seeds so that new plants can reliably replace old plants without being noticed. The old plants only need to be pulled as they deteriorate. Alyssum is white, or pastel hues of pink or purple. Nasturtium is just the opposite, with bright hues of yellow, orange and red, with only a few pastel options.

Pansies and smaller violas are the two most popular of cool season annuals, since they function like petunias for cool weather. They lack few colors. Most have two or three colors. Ornamental cabbage and kale produce big and bold rosettes of pink, white or pink and white foliage. Kale has weirdly distinctive foliar texture. White, lavender, pink, purple and rose stock is the most fragrant of cool season annuals, and taller varieties are great for cutting. Iceland poppy has delicately nodding flowers on wiry stems. They can be pastel hues of white, pink, yellow, orange or soft red.

Johnny-Jump-Up / Violas

91016This is not an easily defined flower. There are hundreds of species within the genus of Viola. Many are known as pansies. Many are known as violas or Johnny-jump-ups. Many are in between. The main difference between these two major groups is that, although very closely related, pansies bloom with bigger flowers, and violas bloom with smaller, simpler and more abundant flowers.

Blue, purple, white and yellow are the most popular colors for viola. Formerly uncommon orange and rusty red have become more popular in the past many years. Colors may be monochromatic, or arranged in intricate patterns with another color or two. The abundant bisymmetrical flowers are only about an inch wide. Mature plants should stay less than six inches tall, and spread as wide.

Violas are technically short term perennials that are typically grown as cool season annuals here. They are unlikely to survive through the innately warm and arid weather of summer. If planted now, they slow down a bit through the coolest winter weather, and then resume for early spring. If planted later in winter to continue slightly later into spring, they last only until the weather gets too warm.

French Marigold

P90921KActually, French marigold, Tagetes patula, is no more French than African marigold is African. All are from Mexico and Guatemala. They were merely popularized and bred respectively in France and Africa. There are now hundreds of varieties. Yet, their color range is surprisingly limited to hues and shades of yellow, orange and ruddy brown. White marigolds are really just very pale yellow.

While African marigold is only occasionally grown for bigger cutting flowers on taller stems, French marigold is much more popularly grown for late warm season annual color. Because it blooms late in summer and early in autumn, and continues only until frost or sustained rain, it is often planted if earlier warm season annuals deteriorate while it is still too warm for cool season annuals.

French marigold can get more than a foot tall, and almost a foot wide, but typically stays closer to the ground. The delightfully aromatic and intricately textured foliage is rich dark green. Removal of deteriorating flowers (deadheading) promotes continued bloom, although a few spent flowers might be left to produce seed. Mildew can be a problem if watering is excessive or late in the day.

Six on Saturday – II: Six More

 

‘Six on Saturday‘ is a popular popular gardening meme that many of us garden bloggers participate in on Saturdays. The link explains how it works. Simply, we post six pictures of what is happening in our gardens or landscapes at the time, along with brief explanations. Mine just posted at midnight. I know I should be done, but I happened to find a few more pictures to share.

These six pictures of marigolds that were just installed at work are not as interesting as the topic I wrote about earlier, but are just too pretty to be discarded before I show them off. The second and third pictures, as well as the fourth and the fifth pictures, might be redundant to each other if they show the same varieties of marigolds, but I do not care. They are all so pretty.

Marigold will not likely be featured in my weekly gardening column this year, because the bigger but related African marigold was featured last October. These here are the smaller and more traditional French marigold. Their bright yellows, bright oranges and rusty reds suit late summer and autumn like miniature chrysanthemums. Their foliage is so delightfully aromatic.

Although I am none too keen on annual bedding plants, I happen to like marigold. They were more popular when I was a kid. They were not so variable back then; and there were certainly none of those pathetic fake white sorts that are really just pale yellow. They were plain and simple orange, yellow and rusty red, in blends or uniform. We could easily grow them from seed.

Unfortunately, marigolds will not be with us for long. They were planted to replace petunias that did not last long enough. At the end of autumn, they will be replaced by cyclamen for winter.

Six on Saturday: White Trash

 

This is getting close to the in-between time for annuals. Warm season annuals that bloomed through summer will soon be getting replaced with cool season annuals that will perform through winter. Of course, our seasons are neither as distinct nor as severe as they are elsewhere. Many annuals are actually perennial here. Some stay later than they should, just because they can.

Aging annuals and perennials can get somewhat trashy if they are not pruned back or replaced soon enough. Their replacements might not be very impressive until they get established and start to grow. So far, only a few violas have been installed here for autumn, and only because the petunias that were where they are now were getting tired prematurely. There will be more.

There is certainly much more color in the landscapes than what these pictures show. White just happens to be my favorite color.

1. Alyssum is supposed to be a cool season annual for spring or autumn. It does not like cold winter weather or warm summer weather. In our mild climate though, it does well in any season. In sunny spots, it self sows to replace itself before it gets old and deteriorates. This batch will eventually get removed, just so we can put something else here. It is prettier in sunnier spots.P90831

2. Dianthus, like alyssum, is supposed to be a cool season annual. It just does not succumb to the minor summer warmth here. Nor does it succumb to the mildly cool winter weather. It could grow as a short term perennial if we did not need to remove it to plants something else later. It also would perform better with better sun exposure. Here, bloom is not as full as it should be.P90831+

3. Viola is one of the cool season annuals that does not do well through summer here. Some survived from last spring, but they were not happy about it. A few of the many might survive and regenerate if we cut them back, but it is easier to plant something new. These white violas, as well as some comparable yellow ones, got planted early to replace prematurely fading petunias.P90831++

4. Petunia is a warm season annual that did well through most of the summer, but is now fading a bit early. Some have already been replaced with violas. Others probably should be. These are still mostly presentable, so can remain for now. If possible, it is better to not replace them with violas too early. Violas that grow too much before autumn can get floppy through winter.P90831+++

5. Phlox was not planted. A single plant grew in an already crowded bed of flashy annuals and perennials two springs ago. There were a few more last year, and even more this year. They all land in good situations, where they unobtrusively grow through spring, bloom in summer, and die back through autumn. They are warm season annuals, but are expected back next spring.P90831++++

6. Geranium, which are really pelargonium, are perennial here, rather than annual like they are in climates with cooler winters. They can be damaged or even killed by frost where they are more exposed, but this particular geranium is sheltered by an eave and trees. They will probably get cut back at the end of next winter, just to stimulate fresh new growth to replace the old.P90831+++++

Morning Glory

90807A landscape designer would have more fun describing both the modern and the good old fashioned varieties of morning glory. Their vivid colors are so resplendent. Their rich green foliage is so luxuriant. Their delicate vines are so elegant. Hey, perhaps this is not so difficult. Anyway, the popular garden varieties of morning glory are descendents of various species of the genus Ipomea.

Except for a few obscure types, and the perennial blue dawn flower, popular garden varieties of morning glory are surprisingly complaisant annual vines, which grow from seed sown at the end of winter. Without getting too invasive or weedy, they sometimes reseed where they get watered, although they might revert to a more feral state after a few generations, or after the first generation.

Some varieties of morning glory have the potential to reach single story eaves, although most stay a bit lower, and some varieties do not get much higher than a doorknob. They work well on small trellises, or even simple stakes, and are just right for picket fences. The simple two or three inch wide flowers are rich hues of blue, purple, red, pink and white, some with spots, stripes or streaks.

Docile Annual And Perennial Vines

90710Most of the familiar vines really are exploitative bullies. They shade the same trees and shrubs that they climb for support. Some will even strangle and kill those who make it possible to get where they want to be. If they do not find trees or shrubs to victimize, they are likely to climb walls and ruin the paint, stucco or siding. Their aggressive nature can be a problem in landscape situations.

Fortunately, there are several vines that are not so aggressive or destructive, such as mandevilla, lilac vine, star jasmine and Carolina jessamine. Other vines that are even more complaisant are light duty perennials and annuals that might grow like weeds while the weather is warm, but then do not have enough time to grow too big or do much damage before they die back through winter.

If flashy color is not important, vining vegetable plants such as pole beans, cucumbers and peas, can cover fences very nicely. On flat fence surfaces, such vines will climb string strung in a vertical zigzag pattern between a horizontal row of protruding nails at the top, and another similar row at the bottom. Unsightly cyclone fences are even better, but will need be harvested from both sides.

Although it is too late to sow beans and cucumbers, a new phase of peas can be sown in mid summer for production in autumn. Fragrant and subtly colorful sweet peas, which are grown for their flowers rather than as vegetable plants, take considerably more effort here. They get started in autumn for the following spring. Trailing nasturtium can get sown at any time, for summer or winter.

As the name implies, perennial pea is a perennial that can get almost rampant, but dies back by autumn.

Passion fruit vine can either be a perennial that dies back to the ground in winter, only to regenerate the following spring, or a somewhat woody vine with wiry stems that survive for several years. Those that retain their vines through winter can get cumbersomely big, or can alternatively be cut back severely late in winter, to behave almost like more docile types that die back for the winter.
