I bought The Watchman seeds in fall of 2023. I used the Winter Sowing method to germinate them during winter of 2024, plopped my little seedlings in the ground that spring and now - finally! - have GORGEOUS 7 to 8 FOOT SPIRES of dark burgundy-black blooms. Amazing! Zone 5a, Iowa USA.

I’ve used your seeds in the past and they turn out so beautiful. I have not had a chance to plant the new ones I bought. I’m very excited to get them in the ground for this spring.
