My beautiful nasturtium! I have always had neighbors comment on all of my nasturtium and I always refer them to Botanical Interests! Every seed germinates! Amazingly beautiful!

Maybe I was sent the wrong seeds but the package said Black Velvet. Otherwise the seeds germinated well.

Which best describes you as a gardener? ProfessionalBIBotanical Interests4/12/26Hey Aileen,
Thanks so much for sharing your experience with the Black Velvet Nasturtium Seeds! We really appreciate you taking the time to leave this feedback.
It sounds like your nasturtiums were absolutely thriving—3 feet is some seriously impressive growth! While our size estimates are based on typical growing conditions, nasturtiums can definitely exceed expectations when they're really happy with their environment. Factors like soil richness, sunlight, water, and even temperature can all contribute to more vigorous growth than anticipated.
We know it can be surprising when plants grow much larger than expected, especially if space is a consideration in your garden. Your experience is really valuable feedback for us and helps other gardeners know what to potentially expect.
We hope you were still able to enjoy those beautiful blooms and maybe even some of the edible flowers and leaves that nasturtiums are known for!
Thanks again for sharing your growing experience with us 🌻
