  • Rock/Alpine Gardens
  • General Garden Use
  • Container Planting

Planting & Growing

Soap Aloe will grow to be about 14 inches tall at maturity extending to 3 feet tall with the flowers, with a spread of 14 inches. It grows at a slow rate, and under ideal conditions can be expected to live for 40 years or more. As an evegreen perennial, this plant will typically keep its form and foliage year-round.

This plant 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 a low-water garden or xeriscape application. 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.

Soap Aloe is a fine choice for the garden, but it is also a good selection for planting in outdoor pots and containers. With its upright habit of growth, it is best suited for use as a 'thriller' in the 'spiller-thriller-filler' container combination; plant it near the center of the pot, surrounded by smaller plants and those that spill over the edges. Note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.
