WINTER-BLOOMING SUCCULENTS2>
Aloe Aloe arborescens
The Aloes are primarily South African natives that range in size from 6 inch to tree-like, but all form rosettes of fleshy, pointed leaves. To me, this is the most striking and imposing Aloe as it forms a large, rounded shrub-colony that over the years can reach 10 ft high and wide. Branching stems carry big clumps of grey-green, spiny-edged leaves. Is is easy to grow in well-drained soil, can take full sun or shade and salt spray, needs little water but can take more. This makes them nice companions to perennials that have similar water- and drainage needs. Its foliage can be damaged at 27 F but will in most cases rebound. In winter, this plant produces spiky torch-like clusters of bright brick-red flowers. A variegated form is also available.
Cotyledon Cotyledon orbiculata
This south African native can quickly reach 2 ft tall, about 2 ft wide. It has fleshy paddle leaves that may be green edged with red or whitish-gray, depending on variety, and carries drooping orange-red bell-shaped flowers from late fall into spring. It is quite drought tolerant and needs excellent drainage and reduced irrigation in summer to prevent roots from rotting. Although my garden is in Zone 20, it has survived many light frosts, and another factor makes this one a great plant in the garden: It is easy to propagate from cuttings, and it also makes a great container plant.
WINTER-BLOOMING TREES
Pearl Acacia (also called Queensland Silver Wattle) Acacia podalyriifolia. Native to Australia, Mexico or the southwestern US, many attractive, winter-blooming and fragrant Acacias are available to us. The evergreen Pearl Acacia grows to 10-20 ft tall and 12-15’ wide with roundish, 1 1/2 inch long silvery gray satiny leaves. It is a shrubby plant that can be trained into a small tree. Brilliant bright yellow puffy and sweetly fragrant flowers are produced in late winter/early spring. It is tolerant of our soils and needs full sun little or no water. The Sunset Western Garden Book recommends to prune the Acacias that are grown as tree form to open up their interiors which will reduce dieback of shaded branches.
Sky Flower Duranta erecta (D. repens, D. plumieri)
This is a fast growing evergreen shrub that can be easily be trained into a small tree. It grows 10-25 ft tall and 6-10 ft wide. Especially as a multi-trunked plant it can make a beautiful specimen for the landscape. Its glossy green leaves are about 2 inch long on broadly arching branches that may or may not have spines. Pretty ½ inch sized violet-blue flowers in fragrant clusters are produced nearly all year and attract people, butterflies and hummingbirds. They are followed by pretty yellow berries (toxic if ingested). It grows easily in most soils in full sun or partial shade, needs only average watering and tolerates temperatures down to around 20 F.
There are also light-blue and dark-blue flowered selections of this shrub available, as well as a white one called ‘Alba’. ‘Sweet Memory’ is thornless, with flower petals edged in white. ‘Gold Mound’ is a small one, only 1 ½ ft wide and high, has brilliant gold leaves and flowers rarely, but it is excellent for adding color to container plantings.
