This is a tall and beautiful dinner plate purple dahlia. If you check out the pictures on this site, the one from Swan Dahlias is the actual color. It blooms for a long time and is great for cut flowers as well as being beautiful in the garden.

I am a pretty amateur gardener. I found the tuber for this at a Family Dollar and was so in love with the color and texture of the bloom in the picture that I bought it for $2.50. I followed the directions for planting it in my modest bed containing very average soil in a sunny spot. My expectations were low.

Without any fuss, It grew. And grew and grew and grew with beautiful, dark foliage and has just produced its second bloom. Gorgeous! Everything I hoped for. It actually takes several days for the bloom to blossom fully, but the color is dark and royal, and rich. Big, fat bumble bees like to roll around in the center. I just love this plant and plan to save it for next year.

Found this georgous thing in a dollar store bin, glad to see high ratings can't wait for it to pop out of the ground.

This is a beautiful dahlia in the garden and is also suitable for cutting. The shade of purple is really lovely and it produces lots of blooms. A favorite of mine!

This dahlia out-performs every other dahlia I have ever grown (over the years, about 50). It makes a full, bushy plant loaded with classic formal decorative, dark purple flowers and produces an unusual amount of seed. With all these qualities of vigor, I think it would be worthwhile to sow the seed, which I plant to do this winter.

Usually, I have sown dahlia seed at room temperature and it germinates within about 5 days. Some use the baggy method. However, according to one source , some dahlia seed has actually been germinated by the winter sowing method in zone 7 (See the DG Winter Sowing Forum for further details).

I don't know how useful it is to know this, but some areas find that dahlias are "only" "occasionally severely damaged" by deer - no telling how far a dahlia can get before that first bite :)
