A solitary, unbranched variety producing a beautiful rosette of large, sea green, sword shaped leaves with red margins and orange-red thorns; orange-red flowers emerge from erect terminal spikes, usually from mid-winter, into spring
Cape Aloe features showy spikes of orange flowers with red overtones rising above the foliage from late winter to early spring. It has attractive bluish-green foliage edged in red. The succulent sword-like leaves are highly ornamental and remain bluish-green throughout the winter. The fruit is not ornamentally significant.
Cape Aloe is a multi-stemmed evergreen shrub with an upright spreading habit of growth. Its strikingly bold and coarse texture can be very effective in a balanced landscape composition.
This is a relatively low maintenance shrub, and usually looks its best without pruning, although it will tolerate pruning. It is a good choice for attracting bees and hummingbirds to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. Gardeners should be aware of the following characteristic(s) that may warrant special consideration;
Cape Aloe is recommended for the following landscape applications;
- General Garden Use
- Container Planting
Planting & Growing
Cape Aloe will grow to be about 10 feet tall at maturity extending to 14 feet tall with the flowers, with a spread of 6 feet. It has a low canopy with a typical clearance of 4 feet from the ground, and is suitable for planting under power lines. It grows at a slow rate, and under ideal conditions can be expected to live for 40 years or more.
This shrub should only be grown in full sunlight. It prefers dry to average moisture levels with very well-drained soil, and will often die in standing water. It is considered to be drought-tolerant, and thus makes an ideal choice for xeriscaping or the moisture-conserving landscape. It is not particular as to soil pH, but grows best in sandy soils. It is somewhat tolerant of urban pollution. This species is not originally from North America. It can be propagated by division.
Cape Aloe makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Its large size and upright habit of growth lend it for use as a solitary accent, or in a composition surrounded by smaller plants around the base and those that spill over the edges. Note that when grown in a container, it may not perform exactly as indicated on the tag - this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
