Tet, Vietnamese New Year’s Day, is today! This is the first day of the Year of the Dog! Tet is celebrated for at least three days, and besides all the popularly known traditions that go along with it, a few horticulturally oriented traditions are also observed.
When I grew citrus back in the early 1990s, I can remember than we sold every kumquat and calamondin tree that had fruit on it prior to Tet. When those ran out, we sold every fruited mandarin orange and tangerine tree, and then every fruited orange and lemon tree. Eventually, just about every fruited tree we could supply was gone. Citrus trees with colorful ripe fruit are traditional decoration for Tet, and might even be a gift for someone lacking such a tree. Kumquat trees are the favorite, but others will do if necessary.
Fruit baskets containing primarily citrus fruits are also very popular and traditional. Bananas, pineapple and any colorful fruit are fair game as well. Shaddock fruit is popular if available. Shaddock is the dwarfing understock for other dwarf citrus trees, but is not commonly grown for fruit production.
Blooming stems of apricot, peach and plum, as well as Saint John’s wort flowers, are the favorite traditional cut flowers for Tet. Each type of flower corresponds to the region of Vietnam from which the family displaying it originated. In the Santa Clara Valley years ago, there were plenty of fruit blossoms to go around. The stems were sometimes cut early and forced to bloom on time for Tet. Nowadays, such blooming stems can be purchased from florists, along with the other traditional flowers; chrysanthemums, narcissus, marigolds, pansies and cockscombs. Families who own a bonsai or more display them prominently for Tet.
Happy Tet and Year of the Dog!
What is it about Australian plants that makes them bloom in winter? Perhaps they think they are still in Australia where it is summer. Whatever the deal is, Geraldton waxflower, Chamaelaucium uncinatum, provides a scattering of small white, pale pink or lavender pink flowers from now until spring. It is no mistake that their bloom resembles that of New Zealand tea tree. They are related.
Okay, so this is not really the time of year that they should be blooming. Torch lily, Kniphofia uvaria, should bloom in the middle of summer. However, without watering, naturalized plants bloom when the weather prompts them to. Some wait out the warm and dry summer weather to bloom as soon as they get dampened by the first rains. Others bloom in spring, before things get too dry.
Here on the West Coast of California, most of us know goldenrod only as a color of crayon. In most other parts of America though, it is a common wildflower that is colorful enough to be popular in home gardens. Yet, with more than a hundred specie, it is hard to say exactly which goldenrod, (Solidago spp.) the crayon color corresponds to. All are some shade of gold or yellow, but some are a bit more orange than others.
Is it coincidence that the Latin name of black-eyed Susan is Rudbeckia, or was Becky rude enough to give Susan her black eye? The dark center is something that all varieties have in common, and what distinguishes them from most of the related blanket flower varieties. The daisy flowers of black-eyed Susan are traditionally yellow. Modern varieties can be orange, reddish or bronzed.
Much of the color in the garden through autumn and winter is provided by foliage. Some foliage turns color as the weather gets cooler. Some had been blue, gray, gold, red, bronze or variegated all year, and just happens to get noticed more now that there is not much other color provided by flowers. There are a few flowers that bloom now or even later in winter, but not nearly as many as there were in spring and summer.
Long before my white supremacy garden (
It makes sense for flowers to bloom in spring. Winter is too cool, windy and damp for both flowers and the insects that pollinate many of them. By summer, successfully pollinated flowers have faded, are busy making seed to disperse in autumn. Some plants produce fruit to get birds and other animals to disperse their seed. There are certain advantages to blooming early in the spring.
