Brachyscome

70125Most of the brachyscome found in nurseries nowadays are the annual Brachyscome iberidifolia. Perennial species are rare. The name is still often spelled as ‘brachycome’, without the ‘s’, as it had been spelled for decades. Although it is a warm season annual, brachyscome is also popular now because it can bloom better through the locally mild winters than the warmth of mid summer.

The blue, lavender, pink, yellow or pale white flowers are like tiny aster flowers. The finely textured foliage forms soft mounds about a foot deep, or mixes nicely with sturdier plants. Brachyscome might work better as a component to urns of mixed annuals rather than as a uniform bedding plant. It likes full sun exposure, but tolerates a bit of shade. Deadheading promotes continued bloom.

Kumquat

80131Tet, on February 16, will be the Vietnamese New Year’s Day for the Year of the Dog! Any year associated with the dog must be pretty excellent. Anyway, potted and fruited kumquat trees are very traditional decorations for Tet. Although less popular than orange and lemon trees, they are the most compact of the citrus trees, so are therefore the most adaptable to compact home gardens.

They grow slowly and may never reach first floor eaves. The evergreen leaves are a bit thicker, smaller and darker green than those of Mandarin orange. Stems are mostly thornless. The compact growth is quite symmetrical, so might only occasionally need to be trimmed for a stray stem here and there. Clusters of small white flowers bloom about the time the last of the fruit gets harvested.

Kumquat has the distinction of being the ‘other’ citrus. Although the genus is alternatively known as Citrus, experts know it as Fortunella. Those with round fruit are Fortunella japonica. Those with oval fruit are Fortunella marginata. The abundant fruits are not much bigger than big grapes, and are eaten whole, with the seeds spit out. The tart pulp with the sweet skin is a tangy combination.

Blue Hibiscus

70118Like euryops daisy, sweet pea shrub and New Zealand tea tree, the blue hibiscus, Alyogyne huegelii, blooms whenever it wants to, even if it wants to bloom sporadically through winter. It should bloom more abundantly in phases though spring and summer, but even that is difficult to predict. The three inch wide flowers are lavender blue, but can be rich purple or white. Pink is very rare.

Young plants can grow quickly but sparsely. Lanky stems can be tip pruned after a spring bloom phase to promote branching and improve density. Growth slows with maturity. Plants can get five feet high and wide in their second year, but might never reach the eaves. They like full sun and shelter from wind, but should not mind a bit of shade. Established plants do not need much water.

‘Silver Falls’ Dichondra

80124No one seems to know what ever happened to old fashioned dichondra lawns. Everyone seemed to like them, especially those of us who dislike turf grasses. Somehow, they became passe and very rare. The formerly common dichondra that such lawns were made of is now merely a resilient weed in turf lawns. But wait! We have not heard the last of this resilient and appealing perennial.

Silver Falls dichondra, Dichondra argentea ‘Silver Falls’, has the same tiny rounded leaves, dense growth and fine texture as old fashioned dichondra lawns, but instead of rich deep green, it is strikingly silvery gray. It does not tolerate traffic well enough to work as lawn, but is a distinctive small scale groundcover, and cascades exquisitely from urns of mixed perennials or hanging pots.

The trailing growth spreads indefinitely over the surface of the soil, but is not very fast about it. As ground cover, individual plants should therefore be planted only two or three feet apart. They get two to four inches deep. Hanging growth (that can not root into the soil) can cascade more than three feet downward. Silver Falls dichondra prefers regular watering and full sun or a bit of shade.

Sweet Pea Shrub

70111It may not always bloom profusely, but sweet pea shrub, Polygala fruticosa, blooms sporadically through most of the year. Even when not much color is evident from a distance, a few flowers can likely be found on closer inspection. For some reason, bloom seems to be quite colorful now. Bloom phases should be more profuse in spring and summer. The pea flowers are soft purplish pink.

Mature plants might only get to two or three feet tall and wide, but have the potential to get larger. They are usually a bit wider than tall, with a nice rounded compact form. The evergreen foliage is slightly grayish light green. Sweet pea shrub prefers full sun exposure, but can get roasted in hot spots. A bit of shade should not be a problem. Once established, it does not need too much water.

Geraldton Waxflower

70104What 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.

Geraldton waxflower is pretty serious about drought tolerance. It can rot and fall over it stays too damp for too long. It likes a warm exposure and well drained soil. It is normal for the tiny evergreen leaves to be somewhat sparse. Unfortunately, it is also normal for healthy specimens in ideal situations to die out within ten years or so. Mature plants can get a bit more than six feet tall and wide.

Austrian Pine

80110Relative to other pines and evergreens that are commonly grown as living Christmas trees, the uncommon and even rare Austrian pine, Pinus nigra, would be a better option. If it gets planted too close to the home, as Christmas trees often do, it does not get big enough to cause major problems. Although much bigger in the wild, local trees may take decades to reach second story eaves.

The species is divided into two subspecie, which are each divided into three regional varieties, which is a fancy way of saying that individual trees may have distinct personalities. Generally, they resemble Japanese black pine, with similar irregular branch structure, but are more dense, and may get a few pendulous stems with age. The dark green needles are slightly shorter and stouter.

The Austrian pine was likely named as such when much of its natural range was still within the Austro-Hungarian Empire, which has since been subdivided into the countries east of the Adriatic Sea. Other larger parts of the range are in Turkey and Spain. Only a small colony lives within Austria, west of Vienna. Austrian pine likes full sun and warmth like it would get naturally back home.

Australian Fuchsia

61228Pictures are probably prettier than the real thing. Australian fuchsia, Correa pulchella, really does bloom with pendulous soft pink flowers through winter when not much else is blooming. However, the flowers are quite small, and the color is rather hazy. The real appeal of Australian fuchsia is that it is so undemanding, and once established, only needs watering a few times through summer.

Mature plants get a bit higher than two feet, and maybe twice as wide, with a low mounding form. The small evergreen leaves have a nice density without any pruning. Obtrusive plants do not mind getting pruned back or even shorn for confinement, but are deprived or their naturally appealing form and texture if pruned too frequently. Good exposure for both sunlight and warmth is important.

Douglas Fir

80103Even those of us who live nowhere near its natural range live closer to Douglas fir, Pseudotsuga menziesii, than we realize. Most of our homes are constructed from Douglas fir lumber. Although very uncommon in landscaped gardens, Douglas fir is the most popular Christmas tree here. Trees introduced for timber have naturalized in parts of Europe, Argentina, Chile and New Zealand.

It is such a grand evergreen conifer that Oregon designated it as the state tree. The tallest trees in the wild are more than three hundred feet tall! Trees that do not compete within a forest do not get even a quarter as tall. The flattened needles are less than an inch and a half long, and arranged on opposite sides of the stems. Light brown female cones with jagged bracts hang downward.

Douglas fir is a native of the West Coast between about the middle of British Columbia to the North, and the Santa Lucia Mountains and the Northern Sierra Nevada to the South, with a few small colonies beyond. Rocky Mountain Douglas fir is another variety from farther inland. Because it is so big and structurally deficient, Douglas fir is almost never planted into landscapes intentionally.

New Zealand Tea Tree

61221With 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.
