Thought for sure that this had died last year as, after I received it from a co-op, it died to the ground. Didn't pull the tags, didn't plant anything else in that spot. Around June 2013, saw some kind of agastache coming up in that spot. Waited until it bloomed before I could identify it. It's Summer Sky. Survived zone 5 w/no mulch or other winter protection. In a semi-shade spot. This plant grew to be about 16" this year and about 8" across. Not as "blue" as I was hoping, more of a muted purpley blue

That's wonderful, Toni! Good to know!

Must be hardier than zone 7, even though Terra Nova lists it that way. I've never grown it before, but might be tempted next year. With all the new varieties Agastache varieties available every year, I been passing it up.
