Purple Gem' Dahlia is indeed a shining gem of the border. Its violet-pink blooms are packed with layers of slender, tapered petals that glow in the summer sun. A cactus-type dahlia, 'Purple Gem' is among the most-vibrant varieties on the market. It looks extra sassy when combined with yellow zinnias, blue cornflowers, and red salvias. (Dahlia)

Plant Information

44" tall x 24" wide. With a bloom span of 6 inches and knock-out coloration, Dahlia 'Purple Gem' is an excellent choice for admiring from both near and far. The bold color of this dahlia means it's easily seen from one end of the block to the other. Deer resistant and practically bug-proof, the lush foliage of 'Purple Gem' is almost as attractive as the flowers. Requiring little input, apart from a sunny site and regular irrigation, this dahlia is a non-stop summertime bloomer and makes a dapper cut flower. Frequent deadheading improves bloom production and flower size, and as with other dahlias, storing the tubers indoors for the winter is a must if you want to grow this dahlia for many years to come.

Q & A

Plant With These:

USDA Hardiness Planting Zones

To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

  • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
  • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
