- Andrea P.Verified BuyerRated 5 out of 5 stars6/4/26Firs
I got these seeds in winter of 2025 and cold sowed them in milk jugs. Only a couple of the Watchmen seeds sprouted and I was a little disappointed. **After two years of doing hollyhocks like that I am thinking it might just be the method and not the seeds.** The ones that did come up were carefully planted and grew slowly. They lasted through this past winter's freezing temps and started off again this spring! I was so surprised to find a bloom (the first one) the other day! I had forgotten which of the plants were Watchman variety vs Chaters Double! I am loving the couple of blooms so far and am looking forward to many more! This plant is about 5 feet tall so far.

Thank you so much for taking the time to share your detailed experience with The Watchman Hollyhock Seeds - what a journey it's been!
I love how you've reflected on the cold sowing method and recognized that germination challenges might be more about technique than the seeds themselves. That kind of thoughtful gardening insight is so valuable! It sounds like you've really learned a lot through your hollyhock adventures over the past couple years.
How exciting that the plants not only survived those freezing winter temps but are now rewarding you with those first beautiful blooms! And at 5 feet tall already - that's fantastic growth! I can only imagine how thrilling it must have been to discover that first Watchman bloom and remember which variety it was.
Thank you for sticking with the seeds and giving them the care they needed to succeed. Your patience and dedication really paid off, and I'm so glad you're loving the results! Here's to many more gorgeous blooms as the season continues.
Keep on growing 🌻️

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.
