Pansy

Violas are smaller versions of pansies.

This is one of the more familiar of winter annuals. Yet, pansy, Viola X wittrockiana, is not just one species. It is a diverse group of hybrids of a few species, and includes viola and Johnny-jump-up. Generally, viola and Johnny-jump-up have smaller and simpler flowers. Pansy generates relatively larger and more colorful flowers, with more intricate patterns.

The most recognizable feature of popular pansy is the distinctive floral patterns that look like floral faces. Individual flowers may display a few distinct colors within such patterns. Alternatively, flowers may be a single color. The color range includes white, blue, purple, yellow, orange, rusty red and black. Big flowers can be as wide as two and a half inches. 

Locally, pansy is a winter annual. The best bloom begins about now. If the coolest winter weather inhibits bloom, it is only temporary. Bloom is likely to resume before a lapse gets obvious. Although pansy is a summer annuals in other climates, it does not perform well in the locally arid climate during warm weather. Plants might get six inches tall and wide.

Winter Annuals Are Moving In

Chrysanthemums bloom between summer and winter.

It is inevitable. It begins at about the same time that cool season vegetable plants start to replace warm season vegetable plants. Cool season vegetables are now in season, and will grow during autumn and winter. They replace warm season vegetables of spring and summer. Winter annuals, or cool season annuals, now do the same for summer annuals. 

Some summer annuals, or warm season annuals, are already shabby by the end of their season. Their replacement is not so unpleasant. Those that continue to perform well into the end of summer or autumn are a bit more difficult to evict. No one likes to pull them up while they still bloom colorfully. Besides, new winter annuals may take a while to bloom.

Winter annuals, as well as summer annuals, require replacement because they live only for a single year. Some complete their respective life cycle within only a few months of a year. That is what their designation as ‘annual’ means. Several annuals have potential to survive as perennials, but are too unappealing to salvage through their dormant season.

Marigold and chrysanthemum are popular for autumn, but do not perform as well through winter. Cyclamen, which prefers a late start, is pleased to replace them by then. Although chrysanthemum and cyclamen are both perennials, few get the opportunity to perform as such. It is easier to simply remove and replace them with the next best seasonal annual.

Pansy, viola, Iceland poppy, sweet William, stock and various primrose are all in season now and through winter. Calendula and snapdragon are seasonable for autumn, and will be again for early spring. They survive and can even bloom through the middle of winter locally. Alyssum is technically a summer annual, but might bloom all through winter also. 

Winter annuals are not as easy to grow from seed as summer annuals are. Because they grow during cooler weather, they grow slower. They therefore need to start growing early to be ready for planting now. It is perhaps more practical to plant most types as seedlings from cell packs. Cyclamen and ornamental cabbage commonly grow from four inch pots. These are innately more expensive than other winter annuals.

Cool Season Annuals Are Cool

Warm season annuals are now passé. Cool season annuls, such as these violas, are in.

Now that it is time for cool season annuals, it is difficult to remove warm season annuals if they are still blooming and healthy. that is probably why so many of us prefer mixed plantings, where cool season annuals can be added as needed to replace warm season annuals as they deteriorate. Some warm season annuals that are actually perennials, like wax begonia and busy Lizzie (impatiens), can be cut back and overplanted with cool season annuals, so that some might regenerate next spring as the cool season annuals finish. Petunias may be looking overgrown and tired, but are at least easier to remove without guilt.

Pansies and smaller but closely related violas are probably the two most popular of cool season annuals. They work something like petunias, but for autumn and winter. They are commonly grown in uniform beds, but work just as well in mixed plantings. There are not many colors that can not be found in pansies, although only a few of the more popular varieties can be found at any particular nursery. Some are ‘solid’ colors. The most familiar varieties have those funny ‘faces’ that pansies are known for.

The various primroses require a bit more effort because deteriorating flowers need to be removed. They can also be a problem for the few who are allergic to them (like poison oak). Like the warm season annuals that can survive as perennials through winter, some primroses, particularly English primrose, can survive through summer as perennials. English primrose displays bright cartoon shades of almost any color. Fairy primrose are more commonly pastel shades.

Stock has an intense and distinctively rich fragrance. Taller types are excellent cut flowers, but are not so practical for uniform beds. Even shorter types are probably best in mixed plantings, or in borders with lower flowers in front. The single or double flowers can be white, pink, purple and almost red.

Ornamental cabbage and kale are grown for bold rosettes of colorful pink, white or pink and white foliage. The shades of pink range from soft light pink to rich purplish pink and almost red bright pink. Cabbage provides more color. Kale has more variety of foliar texture. Ironically, both look rather weedy, and should be removed as they begin to bloom in spring.

Chrysanthemum are strikingly colorful cool season flowers, but rarely bloom as uniformly as they do when first planted. Because they bloom so profusely, they need to be groomed frequently. If they get what they want, they can perform for several years, blooming all sorts of shades of yellow, orange, red, pink, purple and white. Chrysanthemum also displays a broad range of flower structures and sizes, from minute to jumbo.

Sweet William, Iceland poppy, calendula and alyssum are also in season. Yellow or orange calendula, with single or double flowers, is best through autumn, but may mildew by winter. Alyssum is white or subdued shades of pink or purple, and is actually good throughout the year, and can self sow indefinitely.

Color Is Not Black And White

Annuls must change with the seasons.

Several months ago, warm season vegetable plants replaced cool season vegetable plants. More recently, new cool season vegetable plants began to grow from seed, to replace warm season vegetable plants. Annual vegetables grow only within specific seasons. As they finish, they relinquish their space to those that grow in the next season. Annual color operates in the same manner.

‘Color’ is another word for ‘annuals’ or bedding plants that provide colorful bloom. Those that grew earlier were warm season annuals or summer annuals. Those that replace them through autumn are cool season annuals or winter annuals. Of course, there is nothing black and white about color. Some color from last summer can linger late. Some for next winter prefers an early or late start.

Furthermore, much of the color that cycles through gardens as annuals actually has potential to perform as perennials. If cut back and obscured by more seasonable color through their dormancy, some types can regenerate when it is again their season to perform. For example, cut back busy Lizzie that bloomed last summer can overwinter underneath primrose, and start over next spring.

Marigold and chrysanthemum can start bloom early, before summer ends, but may not perform for long. Some chrysanthemum bloom only once, before vacating their space for other cool season color that does not mind starting later. Cyclamen and ornamental cabbage happen to prefer late planting, to avoid Indian summer. Warmth causes cabbage to bolt, and promotes rot of cyclamen.

Pansy, viola and various primrose have always been popular. Sweet William, Iceland poppy and stock are not as common. Stock should be, since it is so delightfully fragrant. Both nasturtium and alyssum bloom nicely through either summer or winter, depending on when they started to grow from directly sown seed. Some fibrous begonia can perform through winter if sheltered from frost.

Most color does well from cell packs. Nasturtium should only grow from seed. Chrysanthemum and cabbage might be better from four inch pots. Cyclamen may only be available in four inch pots.

Not So Annual

These primrose look as good as they did last year.

Among cattle, a cow is a female who has calved. Prior to that, she was a heifer. A bull is an adult male. A bullock is a juvenile male or castrated bull. Most cattle are males who were castrated while young, and are known as steers. Yet, cattle are commonly known collectively as ‘cows’.

Similarly, bedding plants are commonly known collectively as ‘annuals’. Many really are annuals. However, some are biennials; an even more are, to some degree, perennials.

Replacing annuals annually make sense. They grow, bloom and die within one year. Some sow seed to regenerate if and when they get the chance. In the prominent spots of our gardens, not many are likely to get such a chance before they are replaced by other annuals for more immediate gratification within the next season.

The same applies to bedding plants that have potential to perform as perennials. They too get replaced during their off season. Since most are inexpensive, their untimely collective demise is not considered to be too terribly wasteful.

There are a few that are not so easy to part with. Cyclamen will be a topic for next week because it is a cool season perennial that is too expensive to be deprived of its potential to regenerate and bloom next autumn and winter.

These English primrose from last winter were afforded an opportunity to stay in their landscape while they were somewhat dormant through the warmth of last summer, so that they could regenerate last autumn and bloom through this winter. A few from around the edges were moved inward to replace a few that did not survive. Impatiens were planted in front for summer.

The results are not exemplary only because of the shade, but are worth the effort of not putting effort into replacement.

Two seasons for the price of one.

Fairy Primrose

41224The simple pink and white of ‘good & plenty’ candy is what fairy primrose, Primula malacoides, is known for. Pastel purple is also popular. Rosy reddish pink and deeper pinkish purple are somewhat rare. The small flowers are arranged in circular trusses that stand as tall as one foot, just above the softly mounding light green foliage. The rounded leaves are slightly fuzzy. All parts of fairy primrose are toxic, and to those who happen to be allergic to it, can be as severely irritating to the skin as poison oak!

Because they take quite a while to mature and bloom if grown from seed, fairy primrose are typically purchased as cool season bedding plants that are already blooming. Bloom continues through winter and into early spring. If not replaced by warm season annuals, some of the healthier plants can survive through summer to bloom again the following winter as short term perennials. When they do not get enough water from rain, they want to be watered regularly. Fairy primrose can tolerate significant shade.

Why Cyclamen Are So Popular

41224thumbCyclamen are everywhere! Some nurseries have more cyclamen than all other cool season annuals combined. Not all cyclamen are represented though. Almost all are white or simple red. Pink, salmon and other shades of red are noticeable scarce because they are not traditional colors of Christmas. The plants are mostly of impeccable quality, and outfitted with abundant flowers. While there is not much else blooming, the popularity of cyclamen is impossible to ignore.

The problem with cyclamen is the expense. Relative to other cool season annuals, they are large plants that are only available in four inch and larger pots, so naturally cost more. They can not be purchased in less expensive cell packs. Even though they are perennials that can last for many years, they are almost always used as disposable cool season annuals that get replaced when warm season annuals come into season. It can be difficult to justify such an expense for something that lasts only a few months.

The advantage to cyclamen is that they look good instantly, even if they do not perform as reliably during the next few months. This is something that the other cool season annuals have difficulty with. Only larger and more expensive annuals in four inch pots are so immediately colorful, and even they need some time to fluff out and get established in the garden. They just do not grow as fast now as they did earlier in autumn. The weather is now cooler. The days are now shorter.

This is why it was important to replace warm season annuals with cool season annuals earlier instead of later, even if some of the warm season annuals had still been blooming somewhat well. It gave the cool season annuals some time to mature before winter really slowed everything down. Even though they do not grow as actively now, they are already big enough to bloom impressively.

Pansy, viola, stock, Iceland poppy, nemesia, various primroses and ornamental cabbage and kale can certainly get planted now, but will grow a bit slower than they would have if they had been planted earlier in autumn. If necessary, it might be worth planting them a bit more densely than typical, or planting larger plants from four inch pots.

Florists’ Cyclamen

91218It is unfortunate that most florists’ cyclamen, Cyclamen persicum, are enjoyed as cool season annuals only through winter, and then discarded as they are replaced by spring annuals. They can actually survive as perennials for several years, with white, red, pink or magenta flowers hovering above their marbled rubbery foliage each winter. Foliage typically stay less than six inches deep.

Florists’ cyclamen are probably typically discarded seasonally because, after blooming through winter, they take some time to redirect their resources to adapt to their landscape situations as the weather warms through spring. During that time, they can look rather tired. Shortly after they recover, they defoliate for dormancy through the warmth of summer. Some do not survive the process.

When they regenerate through the following autumn, they are not as uniform as they were when first installed. This is probably not a problem where a few florists’ cyclamen are planted with mixed annuals or perennials that compensate for their irregularities as well as their dormancy through summer. However, it does not work well for the uniform flower beds that they are often installed into.

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.

Annual flowers For Cooler Weather

91016thumbAll that unpleasant annual business of removing warm season vegetable plants to relinquish space for cool season vegetables applies to annual bedding plants too. Those of us who do not grow vegetables were spared the agony of pulling up tomato plants that might have still been producing a few tomatoes, just to make room for broccoli. Now, it is time to replace petunias with pansies.

There is a reason why annuals get removed this time of year. It is the same reason why those that get planted now to replace them will be removed later. Annuals are annual. They are expected to perform for only part of one year. True annuals naturally complete their entire life cycles in about a year. Those that have potential to be perennial are too unappealing to salvage through dormancy.

Removal of aging warm season annual bedding plants should be less distressing if they are already deteriorating. By now, most of them are. They tend to wear out faster than some of the warm season vegetable plants. Impatiens can be potted for next year, or, for mixed beds, cut down and overplanted. Most cool season annual bedding plants are already blooming when newly planted.

Because the weather gradually gets cooler through autumn, cool season annual bedding plants appreciate an early start. It is easier to disperse roots before the soil gets cool. Only those that are sensitive to warmth, such as cyclamen, get planted later. Ornamental cabbage and kale might bolt and bloom early at the end of their season if they get too warm at the beginning of their season.

Marigold and chrysanthemum are short term autumn annuals that work very nicely until it is time to plant cyclamen or ornamental cabbage and kale.

Pansy, viola (including Johnny-jump-up), stock, sweet William, Iceland poppy and various primroses are now in season. Some could have been started from seed earlier. Otherwise, it is most practical to plant these cool season annual bedding plants from cell packs. Cyclamen and ornamental cabbage and kale that get planted later are best as more expensive four inch potted plants.
