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.
