Product Details
You can grow breathtaking dahlias from seed and enjoy them year after year. This very tall blend of eye-popping colors is especially suited for the back of the garden, and the long, sturdy stems make them great for cut flowers. Blooms appear about 90 days from sowing, so you can enjoy beautiful blooms come summer. Perennial in USDA zones 7–10; in colder climates, at season's end, tubers can be lifted and stored indoors over winter. Attracts butterflies and other pollinators. Use the edible, mild-flavored petals to garnish salads, desserts, and drinks. (The flower's central disk, while edible, can be bitter.) Dahlia pinnata tubers are edible, with a flavor somewhat similar to raw jicama. The flavor of the crisp, juicy tubers is bland to mildly sweet.

Successfully germinated from both sowing directly in a raised bed and starting indoors two months before transplant. Beautiful blooms and prolific too, bees and butterflies visit all day. Will plant again next year!

That really shows the versatility and reliability of these dahlia seeds. It's so smart that you tried both methods too - now you know you have options for timing and can choose whatever works best for your garden schedule each season.

These were very easy to grow and came in so many beautiful colors. I saved the tubers over the winter for the colors I liked most and will plant more from seed this year to see what I get.

I had a great experience with Botanical Interests Cactus Blend Dahlia seeds last year. I am trying the Double Blend Dahlia mix this year and starting early indoors. The germination rate for my packet was 90%. Thank you so much for the great seeds! Hope to update what the flowers are like in a few months.
