Check out this web site for the hot scoop on Mystic Spires (see link below). I use google all the time to get information on plants, that is how I got this link. Enjoy it! I recently bought May Night Salvia on an impulse purchase, need to get it in the ground soon.

Have fun!

Here is a link that might be useful: Mystic Spires Salvia Information

I purchased Mystic Spires here in the UK last year, and had thought that after a year, it would attain the size of Indigo Spires. But I was wrong, and here it only grew to 2 ft. It survived the winter outside. For insurance, I took cuttings of both forms for the greenhouse. Both flourished, and now, Indigo is twice the size of Mystic. Also Mystic already has flower buds. The link that Joseph sent describes it very well.

It can only be propagated from cuttings, as it is a sterile hybrid farinacea x longispicata.

It is a seriously good Salvia!

I think it is brilliant. It is neat and tidy and was in full flower for 14 weeks last summer in the UK. I am glad to hear Robin that yours survived outside. I didn't take the chance, I cut it back hard and overwintered it under glass. It outside now and growing away strongly.
