With such an odd variety of flowers blooming out of season, it should be no surprise that New Zealand tea tree, Leptospermum scoparium, decided to join the party. It starts blooming in phases in spring, and continues into autumn, so is not too terribly out of season. Besides, some varieties are known for spontaneous bloom phases at any time of year. Bloom can be pink, white or red.
The finely textured and aromatic evergreen foliage is slightly prickly to touch. Individual leaves are tiny and rather narrow, with pointed tips. Flowers are also tiny, but compensate with profusion. A few varieties have darker, almost bronzed foliage. A few varieties have fluffier double flowers (although the flowers are no wider than single flowers). The weight of bloom can cause limbs to sag.
Most garden varieties can reach the eaves. Larger varieties can eventually get to upstairs eaves. With minimal pruning, New Zealand tea tree is a colorful big shrub, with blooming stems from top to bottom. Alternatively, it can be an excellent small tree, with lower stems pruned away to expose the finely furrowed bark of the main trunks. It wants full sun, but not much else once established.
Those who can grow Mexican lime, Citrus aurantifolia, get to brag to their friends who can not, even if they are only a few miles away in slightly cooler spots. It really is marginal here. If it gets too cool in winter, it can defoliate. Frost can damage or kill the stems. Because it stays smaller than other citrus, Mexican lime happens to do well in large pots that can be moved to shelter for winter.
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.
These pale blue . . . whatever they are, were just too cool to pass up without a picture. Technically, they are the ‘cones’ of dwarf golden arborvitae, Platycladus orientalis (formerly Thuja orientalis) ‘Aurea Nana’. They do not look much like cones. They are only about three quarters of an inch long, and are rarely as profuse as they are here. They are less appealing as they dry and turn brown.
It is about time that someone reintroduced this technique! Blue Princess holly is now available together in the same pot as its male pollinator, Blue Prince holly (Ilex x meserveae ‘Blue Princess’ and ‘Blue Prince’). With careful pruning to prevent one from crowding out the other, both can coexist and provide profuse, bright red berries every winter, indefinitely. As the plants grow, their main trunks will eventually graft together.
The Latin name is easy to confuse with the sacred flowers of an aquatic perennial from tropical regions of Asia, or a funny looking British sport coupe. Lotus berthelotii is a diminutive terrestrial perennial known as parrot’s beak. It gets only about a foot high, and spreads to only two or three feet wide. It cascades nicely from hanging pots, and is actually rarely planted out in the garden.
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.
We all know about the bad reputation of eucalypti, especially the notorious blue gum. They are too big, too aggressive, too messy, too structurally deficient, and in groups, they are too combustible. However, there are several eucalypti that are not only appropriate for local home gardens, but because of their resiliency, drought tolerance and adaptability to the local environment, should be more popular than they are.
Known more as a medicinal herb, and by its Latin name, coneflower or Echinacea, is a delightful prairie wildflower that works just as well in refined home gardens. It blooms in summer and again in autumn, although autumn bloom can be inhibited if plants are not groomed of deteriorating stems from the previous bloom. Like related gaillardia and rudbeckia, coneflower is a nice cut flower.
