They are the same color. However, Mystic Spires has a different form than Indigo Spires. Indigo is a far laxer, more sprawling plant which always needs staking. Mystic's form is like its other parent, farinacea, except bigger. Mine get about two to two and a half feet high and about eighteen inches wide. Also, the blooms of Mystic are like farinacea's in form. Indigo Spires blooms never seem to end. Mystic's do end, but retain their blue color even as they dry. I deadhead to keep them coming. I have had Mystic Spires for three years now and they are, hands down, my favorite salvia. They bloom early (already blooming here) and don't quit till frost. They never need staking, and bounce back very fast after cutting back. Although I always have a few that overwinter, I take cuttings in the late fall, just in case. They root easily. I overwinter them in my unheated basement under lights. Rarely lose even one.

My favorite salvia the last couple years is "Black and Blue" Salvia. The hummingbirds love it and I just bought a couple today at $4.99 each at Fred Meyer. I have seen them at specialty nurseries for 8.99 and up.

Ugh! I hate it when this happens! Always happens to my S. Leucantha, usually after a downpour of rain while its at over 3 feet. What I do is I stake around it and tie just like Westelle mentioned. It works for a bit but once it gets at 5 feet or so, the it grows out and over and doesnt look to well. Im going to prune that sucker to the ground completely this year. The small short dead canes from previous prunings I have noticed are sort of creating the plant to be 'pushed away' from the middle area, making the outside branches more prone to laying flat.

Hello, I'd like this if you still have it. Please check my have list.
