- Shane H.Verified ReviewerRated 5 out of 5 stars8/3/26Pollinator Paradise and Fun For Kids
The anise hyssop has been a hit with the kids since it brings pollinators around every day! It also helps the other plants we have in our small garden. I will definitely grow these again. The seeds had 100% germination rate for us.

They grew too well! I didn't separate them well enough and am having to pull small ones out as the larger plants root. I will have some sterdy plants by end of summer and put them in the ground and hope they survive the winter and grow next year to maturity.

I used germination sponges followed by cow pots. I also used a heating mat and grow lights. Really good success rate

- Rebecca H.Verified BuyerRated 5 out of 5 stars4/23/26Good germination
Did both a winter sow and traditional indoor sow after cold stratification and had good germination with both. Seedlings are looking happy. Picture of winter sown jug in April zone 7b.

We're so happy to hear you had great germination with both your winter sowing and indoor cold stratification methods! It's awesome that you experimented with different techniques and got fantastic results with both! Your seedlings look so healthy and happy in that photo. You're going to absolutely love these plants when they mature - anise hyssop produces such beautiful purple flower spikes that pollinators go crazy for, plus those leaves have the most amazing licorice-mint fragrance! Thanks for sharing your growing experience and that great photo from your zone 7b garden! Keep on growing 🌻️
- Tiffany T.Verified BuyerRated 1 out of 5 stars4/22/26Poor germination
Sprinkled out the whole packet and got one seedling. I've grown this every year and while it can be hard to get it to germinate in my climate, I've never had such poor results.
