Aloe Vera

*Aloe barbadensis*

How to know it

A rosette of thick, fleshy, grey green leaves with soft spines along the edges. It stores water, so the leaves feel heavy and firm. It survives neglect better than almost anything else you can grow.

What it does

The clear gel inside the leaf is applied to minor burns and sunburn, a use so widespread it needs no introduction in most households. It also holds a great deal of water, which is why the plant survives dry season.

Safety

The gel is safe on skin. The yellow layer just under the skin of the leaf is a strong laxative and should not be eaten by children. Teach that the clear part is the useful part and the yellow is not.

Two things to do with children

Cut a leaf across and let children touch the gel. The texture is unlike anything else in a garden and holds attention for a long time.

Compare an aloe leaf with a thin leaf from another plant. Ask which one could survive a week without rain and why. Children work out water storage from the feel of it.
