- DVerified ReviewerRated 5 out of 5 starsMar 13, 2026Fun but not quite purple
I love being an able to put some slightly different colors into my nasturtiums! I planted them last spring & summer and they were slow to get going. This spring they’re popping up nicely. Seems like about 4/5 of the blossoms are a faded mauve color, and the remaining 1/5 are almost magenta. Not really purple but still lovely.

Thank you so much for this wonderful 5-star review and for sharing your experience with the Purple Emperor Trailing Nasturtium Seeds! It's fantastic to hear they're popping up nicely this spring after getting established last season.
Nasturtium colors can vary based on soil conditions, temperature, and even the individual genetics of each plant, which creates that beautiful range you're experiencing.
We love that you're enjoying the slightly different colors they bring to your nasturtium collection. Those trailing varieties add such a lovely cascading element to gardens, and the color variations you're describing sound absolutely gorgeous!
Thanks for sticking with them through that slower start last season.
Keep on growing 🌻️

Years ago grew one and have been looking for the elusive pink one. After much searching, I gave this seed mix a try and I got all shades of dusty pink, orange-pink, blush, to pinkish, to red-pink. Was very vigorous and took over the boulevard.

I don’t really like to write negative reviews but, these flowers are not what I was expecting . I got very sparcly petaled flowers, and not the colors on the seed packet.

- Melody P.CA, United StatesVerified ReviewerRated 4 out of 5 starsJun 1, 2025Great trailing variety & pretty colors
Very prolific! Grew well in our mild winter in zone 10b. I really enjoyed it softening the edge of my raised bed. 4/5 since I did wish the color was more vibrant.
