It is either a biennial or a short lived perennial, depending on your zone.They self sow quite nicely, so just look around and try to spot some of the seedlings.You will, of course have to wait until next year for the flowers. Trying to get the alternate generations going on something like this can take forever if you are like me and either forget to gather the seeds or forget to plant them.It has taken me 5 years to get the two generations of clary sage going in my garden.

Thanks for info., Newine. I actually thought it was a native plant. I don't think I'll have any seedlings since I collected all the seeds, but I do have some left so maybe I'll sow some in the summer. Hope they'll germinate without cold strat. I really love the flowers and I am a little disappointed - had two plants and now nothing. But I am learning to be very patient as a gardener, and there's always one more thing to do. Thanks.
