Types of rosemary: trailing, creeping, upright & hardy rosemary varieties
Rosemary is generally thought of as the simple culinary herb. What most people don’t realise is that there are many surprisingly diverse cultivated varieties of this Mediterranean native.
Rosemary (Salvia rosmarinus) is a wonderfully aromatic herb in the plant family Lamiaceae. This is the same family that the other typical Mediterranean herbs, lavender (Lavandula angustifolia) and sage (Salvia officinalis), belong to. There are many types of rosemary that are available in the market now, from upright to trailing growth forms, floral displays in blues, pinks, whites, or purples, as well as some that are more aromatic than others. This article will introduce you to the most popular varieties so that you can choose the right one for your garden.
