Their 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.
Just because California bay, Umbellularia californica, can be used like Grecian or sweet bay for culinary purposes does not necessarily mean that it should be. California bay has a stronger and much more pungent flavor and aroma. Some might suggest substituting less than half California bay for Grecian bay. However, even if the intensity is adjusted accordingly, the flavor might be off.
Ferns tends to be . . . well, ‘ferny’, with divided or intricately lobed foliage. Staghorn ferns and bird’s-nest ferns are the more familiar of the rare exceptions. Staghorn ferns have two types of simple undivided fronds, and both types lack rachi. Bird’s-nest ferns have weirdly simple fronds that, although equipped with prominent rachi, lack any distinctive division or lobes that make ferns ‘ferny’.
If it has bark like a coastal redwood, and foliage like a coastal redwood, and a slender conical structure like a coastal redwood, it is most likely a coastal redwood. If it turns orangish brown in autumn and defoliates through winter, it is the much less common dawn redwood, Metasequoia glyptostroboides. It is one of only a few distinctive genera of coniferous trees that are deciduous.
Not all annuals last as long as petunias do through summer, or pansies do through winter. Some fill in for the in between seasons, or if longer term annuals do not last quite as long as they should. Cockscomb, Celosia plumosa, blooms best now that it is about halfway through summer, and then finishes as weather gets too cool for it in late autumn, not so much more than two months later.
Plants are usually well suited to the climates that they are native to. Glaucous (slightly reflective grayish) foliage is more common in harsh climates where darker green foliage might get cooked by the sun. Pendulous growth is more common among plants that want to shed heavy snow efficiently. Kashmir cypress, Cupressus cashmeriana, has both, but is from a tropical monsoonal climate.
Those outside California sometimes envy our ideal climates and soils. More of a variety of plants can be grown here than in most other places in America. There are not many plants that can be grown elsewhere that will not grow here. However, phlox, Phlox paniculata, is an example of a plant that can do well here, but for some reason or another, is much more popular everywhere else.
Good 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 common names of ‘Dutchman’s pipe’ and ‘queen of the night’ are not much less awkward the the Latin name of Epiphyllum oxypetalum, which might be why the Latin name is more common than the common names are. Some know it as ‘white ephiphyllum’ or even more simply as ‘white epi’. It is one of the more popular of the epiphyllums; and it is the most popular with white flowers.
