How do we use your location?
Knowing your location helps us recommend plants that will thrive in your climate, based on your Growing Zone.
Dahlias are perennial in zones 8-10, but in cooler zones, tubers can be dug after frost comes, stored over winter, then re-planted the following spring. Grow Dahlias in a sunny spot, in average soil that drains well. Keep moisture consistent once it begins to grow and enjoy a non-stop color parade. Deadhead spent blooms to encourage more flowers and pinch off small side buds to encourage larger flowers if desired.
As soon as your order is placed you will receive a confirmation email. You will receive a second email the day your order ships telling you how it has been sent. Some perennials are shipped as potted plants, some as perennial roots packed in peat. The ‘Plant Information’ section describes how that item will ship. All perennials and fall-planted bulbs are packaged to withstand shipping and are fully-guaranteed. Please open upon receipt and follow the instructions included.
Perennials and fall-planted bulbs are shipped at the proper planting time for your Growing Zone. Perennial and fall-planted bulb orders will arrive separately from seeds. If your order requires more than one shipment and all items are shipping to the same address, there is no additional shipping charge. See our shipping information page for approximate ship dates and more detailed information. If you have any questions, please call Customer Service at (802) 227-7200 or contact us by email or chat.

"Beautiful blooms with nice long stems"
"I have grown these beauties for the past 3 years now among many other Dahlia varieties and it is always the first to show up and start the Dalhia party. I usually have to practice great patience for the arrival of Dahlia blooms each season in my cooler climate. Purple Gem is always a welcomed sight as it starts shooting off bright fireworks of electric color with its exotic cactus-style flair. It has a shorter vase life than most Dahlias but that's to be expected for a cactus dahlia. It still packs a punch in a vase, especially with cactus style zinnias. The bees also seem to be particular to these blooms as the centers open up. It stays prolific until the first frost arrives. The tubers have multiplied nicely each season and that has made it lovely to share with others!"
"This is my first experience with cactus dahlia and I'm hooked. The color is a little darker than the pictures; between a hot pink and purple. I love it! The the way the pedals curl adds a unique texture and is a great Co trast to the standard dinner plate dahlias. A note on planting: the instructions said plant 4" deep. These were large tubers so the HOLE might need to be 4" deep to hold the plant, but the crown should sit at or just below the surface. Plant them 4" deep and they will struggle to get to the surface."
"Great purple with long stems. Lots of blooms and health plants. One of my best performing dahlias. Not super showy as cactus varieties go. Great in big bouquets. Produced healthy tubers at the end of season."
"Love the long stems great in arrangements with other garden flowers"
"The name Purple Gem is a little deceiving, I would say it's more of a pink fuchsia in color than it is purple. But it was very pretty and held up well bouquets."
