About Aloe × spinosissima – Spider Aloe

Aloe × spinosissima, commonly known as Spider Aloe, is a vigorous evergreen succulent valued for its dense clumping habit, narrow arching foliage, and prolific flowering display. The blue-green leaves are edged with soft white teeth and form attractive rosettes that gradually develop into substantial clumps, providing year-round structure and texture.

It performs best in full sun to light shade and free-draining soils, adapting well to coastal conditions, dry climates, and a wide range of landscape settings. Spider Aloe is one of the most reliable flowering aloes, producing abundant flower spikes while maintaining excellent drought tolerance once established. Its robust growth habit makes it suitable for both residential and commercial landscapes.

They look excellent when used for mass planting, borders, coastal gardens, wildlife-friendly landscapes, rockeries, and waterwise gardens where dependable flowering and evergreen coverage are desired. The nectar-rich flowers attract birds and pollinators, adding valuable habitat benefits to the garden.
