This low-growing shrubby plant makes a good shelter for tortoises and won't harm if nibbled. Please note that if you buy a heather plant that has been artificially coloured you should not feed it.
The main differences between Heather and Heath are that Heath is not quite as good at tolerating cold temperatures as Heather, and Heather has flat scale-like leaves with very tiny hairs that can give them a greyish tinge, whereas Heath has needle-like leaves. The flowers of Heather are generally Bell-Shaped. See also Heath.
