This perennial will eventually grow to 48 – 60 inches (120 – 150 cm) in height if it will stand your winters. Desiring a well-drained, light, and well-limed soil and full sun. It can be reproduced from cuttings and by layering. Germination of seed and growth of the tiny seedlings is very slow.

There is a beautiful, upright variety called “Miss Jessup”, which is found slightly hardier than the common Rosemary. There are several prostrate Rosemary, none of which is hardy, though R. Officinalis humilis is the least tender of them.

It is very hard to say how much frost Rosemary will stand.
Suggestion – leave one or two mature plants outside, until you know what your winters will do to them. Take all the others, especially the young ones, into the greenhouse during the cold months. In a winter temperature of 7 degrees C, they will thrive. Be very careful to harden them off slowly in the spring, before you plant them in the garden again.

Rosemary is used for flavor in the kitchen, in medicine, in cosmetics – especially in hair preparation – and in the perfume industry.
