Vampire Slayer is a super strong plant. It was planted May 2021 here, I'm pretty sure only one or two fans. It bloomed in 2021 from June 4- July 10 with 27 flowers. That was super early as it was from Northern Lights and grown in a greenhouse. By October it was up to five fans.
In April of 2022, Vampire Slayer was at 6 fans. Then, last summer, Vampire Slayer bloomed from July 15-August 17 with at least 53 blooms photographed. There were probably more as I was gone some in August. Even after all that activity, and drought, it was up to 11 fans by April 2023.
It's a really beautiful plant, once it unbends and gets used to it's spot.
