I got 'Blackthorne' from G. Wild in April here in zone 7A. I had my first scape 6/8 after it had been in the ground 68 days and the first bloom on 6/27. It performed well with beautiful blooms here. I'm looking forward to seeing it grow into maturity. The image below is from 7/9 as 'Blackthorne' shot up single blooms for about 3 weeks as a first year cultivar that started with a very small fan.

I've had Blackthorne for quite a while. It isn't a great increaser for me here in zone 5a. I must admit though, it is in one of the gardens that usually is the last to get attention. Sometimes gets skipped all together. So this spring I gave all the DL's in that garden a dose of alfalfa pellets. It really perked up this year from that and all the rain we had. I feel guilty for mistreating such a beautiful daylily all these years.

Blackthorne did well here for a few years. It slowly went down hill because of increasing shade. I moved it to a different location this Spring where it got full sun. It is slowly making a comeback. I'm glad to see it doing better because it is one of the better dark-eyed cultivars. There is nice contrast between the eye and the rest of the flower. Only negative is the scape. It could be slightly stronger, and about four inches longer.
