This plant loves it in San Diego. It grows magnificently and needs NO water once established. Watering it can kill it fast.

I rooted tip cuttings in little prepared peat packages and it took no time at all. It will cover 8X8 feet or more, I'm still watching to see how far it will go. It is beautiful, flowers profusely, and is a great boon to arid areas due to its low water needs.

I could pass some around if I knew how to ship.

Rating neutral as new in my garden. It is often confused with jacobea maritima, which has similar silver, velvety foliage but yellow flowers. Centaurea cineraria has a blue, thistle-like flower. In my area some people commonly call it giant dusty miller but that can only lead to confusion.

UPDATE 02/13: has grown to 2' x 2' in less than 1 yr. No blooms yet. Changing rating to positive as it has been a very easy plant to grow. It looks a little out of place in its present location but I've been warned that it doesn't like transplanting. For now, I will trim as needed.
