    About Aloe × spinosissima

    Aloe × spinosissima, the Spider Aloe, is a vigorous evergreen succulent hybrid with narrow arching blue-green leaves edged in soft white teeth. Rosettes spread outward and build into wide clumps over time, and the plant flowers heavily, sending up branched spikes of orange tubular blooms in the cooler months.

    It grows in full sun to light shade in any free-draining soil, including poor sand and rocky ground. Annual growth is around 30 to 60 centimetres, quick for a succulent. Light to moderate frost, coastal wind and extended drought are all tolerated once established, and no summer watering is required.

    The spreading habit makes it useful on embankments, batters, wide verges, erosion prone slopes and large scale mass plantings where the brief is coverage rather than a specimen. It is also a strong performer in habitat and wildlife plantings. Where a big area needs filling quickly and permanently, it delivers.

    Frequently Asked Questions

    About Spider Aloe

    What is Spider Aloe?

    Spider Aloe is a naturally occurring hybrid Aloe, thought to have arisen from Aloe arborescens crossed with Aloe humilis. It forms spreading clumps of narrow toothed blue-green leaves and flowers prolifically in orange through winter and spring. It is one of the toughest and most widely planted aloes in Australian landscapes.

    How big does Spider Aloe grow?

    Individual rosettes reach about 60 centimetres to 1 metre high, and a clump spreads to around 1.5 metres wide over several years, continuing outwards as offsets root down. Flower spikes stand roughly 30 centimetres above the foliage. Treat it as a spreading groundcover succulent rather than a fixed specimen.

    How fast does Spider Aloe grow?

    Around 30 to 60 centimetres a year in sun and free-draining soil, which is fast for a succulent and quicker than most of the aloe hybrids. Plants from 30 centimetre pots typically close a mass planting within two seasons. Growth slows markedly in shade, or in heavy soil that holds winter moisture.

    How far apart should I plant Spider Aloe for mass planting?

    About 1 to 1.2 metres apart suits its spreading habit and gives closed cover within roughly two years. On slopes and batters where quick coverage matters, 80 centimetres is reasonable. Planting tighter than that wastes plants, because the clumps merge and the outer rosettes lean as they compete for light.

    Does Spider Aloe attract birds?

    Yes, noticeably. It flowers heavily through winter and spring, and the tubular orange flowers are a strong nectar source for honeyeaters and lorikeets at a time when little else is out. Native bees work the flowers too. It is one reason this aloe turns up so often in habitat and biodiversity plantings.

    Is Spider Aloe safe around pets and children?

    The leaf margins carry firm teeth, so it is worth setting it back from paths where small children play. Like other aloes, the sap contains compounds that can cause stomach upset if the leaves are eaten, so it is not the best choice within reach of dogs that chew plants. It is not otherwise hazardous.

    How do I care for Spider Aloe?

    Cut spent flower stems at the base and pull out any dead rosettes from the centre of an ageing clump, which keeps it looking deliberate. Water through the first summer only. It needs no fertiliser. Every few years, lift and replant rooted offsets from the edge if the middle of a clump has thinned out.
