Here is a link that might be useful: all about angelica

A beautiful herb. Cyrus is correct, it does love sun and water. Since angelica is a biennial, there is no real "spread" to speak of. The plant does get very sizable in its second year when it is ready to bloom. The actual height varies - the happier it is, the larger it can get. But don't worry, it doesn't stay that big. It dies after blooming.

This is one of the plants I go out of my way to plant each year. I love the way it looks. I've never used it herb-wise - I don't have the heart to chop on it. It's too pretty. Anyways, there are recipes on-line for candied angelica and more.
