Most of us are familiar with Aloe vera, the fleshy, succulent plant commonly grown as a houseplant in Britain and used to treat minor skin ailments such as scalds and sunburn. But did you know the Aloe genus contains more than 500 species? These shrubby, succulent plants are native to Africa, Madagascar and Arabia – several of them can be grown here as houseplants while some hardier species can even be grown outside in summer.
Most aloes have a rosette of sharp, pointed fleshy leaves, often with spots or spines, along with occasional yellow or red flowers. They look beautiful grown as part of a cacti and succulent display – both in the house and outside in gravel gardens and summer succulent displays.
How to grow aloes
Like all succulents, plants in the Aloe genus thrive in a nutrient-poor, free-draining soil. Grow them in pots of peat-free cactus compost or a similar mix made from peat-free multi-purpose compost with added horticultural grit, sand or perlite to aid drainage and reduce nutrients. Porous pots, such as terracotta pots, work well as the compost dries out more quickly than in plastic pots. Water sparingly in summer and avoid watering at all between autumn and spring – if you’re lucky your aloe may flower.

Aloe striatula is native to the mountains of South Africa, where summers are hot and dry, and winters are very cold. It’s therefore an incredibly hardy aloe, which can be grown outside all year in most parts of Britain. It has a sprawling, scrambling habit and may even climb if given support. Its fleshy leaves are striped different shades of green. In summer it bears tall, dramatic flower spikes similar to kniphofia, and it eventually forms a branching, woody trunk. It’s perfect for growing in a dry, gravel garden, where you don’t have to worry about getting it through winter.

Lace aloe, Aloe aristata, forms rosettes of fleshy, lance-shaped, softly spined green leaves with white spots. In autumn tubular, orange-red flowers appear on long stems. Although hardier than many aloes, lace aloe is best grown as a houseplant or in a greenhouse.

The most commonly grown aloe, Aloe vera bears sword-shaped, succulent leaves. Markings on the foliage can vary in the species – some have glaucous, pale foliage while others have rich green leaves flecked with pale spots. Spikes of tubular yellow to orange flowers appear in summer, but rarely in the UK. It’s a handy plant to grow in the kitchen as you can break off leaves and spread the aloe juice on burns and scalds, to reduce likelihood of your skin blistering.
