I lover the tall blue ageratum seeds I purchased from Botanical Interests. The foliage on the plants is lush with lots of branching and the seeds germinated well.

Looking forward to planting and seeing these beauties grow. Easy to grow. The flowers in the picture are from my garden today. I live in Zone 9 and look how healthy they are. 100° today.

I was so excited to try growing these flowers for the first time - they look beautiful from my research and the photos. The packet came with 25 seeds and I started them in Epic trays, pressing them onto the surface of the soil. Nothing has popped up and it's been 3 weeks, SoCal. Bummerrrrr

- Douglas D.Verified BuyerRated 5 out of 5 starsApr 18, 2026All seeds germinated
All the seeds germinated and they are currently growing under my plant light. Up here in central New York State they can't be planted outside until end of May.

Thank you so much for the 5-star review! That's fantastic news that all your Blue Planet Ageratum seeds germinated - what a great success rate! It sounds like you're giving them the perfect start under your plant light while you wait for the weather to warm up. End of May is definitely the smart move for central New York - those last frost dates can be tricky! Your patience will pay off when you get those beautiful blue blooms in your garden. Keep on growing 🌻

I was running low on these seeds and decided to go with Botanical Interests. I had great germination and the seedlings are growing like crazy. Looking forward to planting them out in a few weeks.
