- Addison y.Verified BuyerRated 5 out of 5 stars3/12/26Pretty easy to start
I am stoked about these. I did some cold stratification then reread the suggestions and realized they didnt need it. Brought them back in and they popped right up. Getting their real leaves. Would Def recommend.

What a great learning experience with our Purple Coneflower Echinacea Seeds! We love that even after the cold stratification detour, they bounced right back and popped up beautifully once you brought them back inside. It's so exciting to hear they're already getting their real leaves! These gorgeous purple blooms are going to be absolutely stunning in your garden, and the pollinators are going to love them too! Keep on growing 🌻️
- DianaVerified ReviewerRated 5 out of 5 stars3/6/26Excellent germination
I purchased coneflower seeds from Botanical Interest and a competitor brand. The seeds from Botanical Interest outperformed and had a higher germination rate. I started my seeds indoors using a heat mat and a growing light. I also cold stratified the seeds in my fridge for 7 days. The seeds started germinating after 5 days. I have 42 coneflower seedlings growing now. I highly recommend this company. I will purchase another packet and experiment growing the seeds without stratifying them.

You're seedlings look great! We're thrilled to hear our Purple Coneflower Echinacea Seeds outperformed the competition with such excellent germination rates! Your setup sounds perfect - the heat mat, growing light, and cold stratification clearly paid off with those amazing results. 42 seedlings is incredible! We love that you're planning to experiment with another packet without stratification - it's always fun to compare different growing methods. Thank you for choosing us and for sharing this wonderful comparison and your growing expertise with us. Keep on growing 🌻️
