Bay leaves come from a small tree known as Laurus nobilis. I don't have a bay tree yet, but its on the list of perennial herbs that I would like to grow. I use a lot of bay leaves and lately I've been lucky to pick up fresh leaves from our local community share. I dry the leaves and keep them in a jar in my spice cupboard. How to grow bay While bay trees are usually described as "small", they can grow to 15m, so they need to be managed to keep size under control. The tree can be propagated from cuttings or seeds. It does not tolerate cold temperatures below -15degC. They can be kept in pots, but I'm planning on planting one in the garden as I don't like having to remember to water plants in pots. How to use bay leaves I put bay leaves in everything! Well not everything, but if I'm making a stock, soup, casserole or curry I will pop in 2-3 bay leaves. They add flavour to any slow cooked dish....
