- Joyce F.Verified BuyerRated 5 out of 5 stars4/28/26Marvelous seedlings!
My seedlings grew beautifully, and I just put them outside a few days ago. They are doing well even though I started them indoors. Some nasturtiums don't like that.

- Shannon M.Verified BuyerRated 4 out of 5 stars4/28/26Good germination
These germinate well as long as the seeds are nicked and soaked. As for the plants, they are a bit leggy and are tethered to the dirt by a thin root, but maybe that's just how they grow.

We're so happy to hear about your excellent germination success with our Purple Emperor Trailing Nasturtium Seeds! The nicking and soaking technique can really make a difference! It should develop stronger root systems as they mature and start their beautiful trailing habit! Thanks for sharing your growing experience with us! Keep on growing 🌻️
