Aloes are succulent plants. meaning the leaves have thick, juicy leaves which helps the plants survive in hot dry climates. The rosettes of leaves have a waxy surface and are quite attractive, and vary in colour from blue- green to other shades of green, and often with interesting patterns. The flowers are quite special,, and the hybrid varieties can be spectacular. Flowering in late winter, the flowers form in spikes of many colours, depending on the variety. Plant varieties can vary from short under 1 metre high to tree-like specimens, so there is one to use for most garden situations. Plant them in a full sun position with well-drained soil, and water them sparingly. Thye grow best in Warm and temperate climates, but will not tolerate frosts.

I photographed these Aloes in a local Sydney Nursery. The flowers have not yet opened, but the plants are very handsome.
