Dahlia Manhattan Island Bulb

You won't believe the size of these blooms until you see them for yourself. Truly as big as dinnerplates, these blooms will reach up to 10 inches in diameter, bringing more color than you can possibly imagine.

Gigantic, fully-double flowers emerge in early summer with a blaze of fiery red color. The dense petals are a deep red that fades to a bright, golden yellow in the center. There are so many petals, that the blooms slowly open, sometimes leaving an ornamental ball of pinkish-yellow petals in the center.

Dahlia Manhattan Island reaches about 30 to 40 inches high, you might not think the tall sturdy stems can bear the weight of the huge blooms, but don't worry they will manage. However, if the stems begin to droop, you can always support them with the help of a stake. For the dahlias that reach 32 inches or more, staking might be required, especially in windy conditions.

This perennial is the perfect size for a variety of landscaping needs, including borders and containers. And you won't be able to resist cutting a few of these stunning flowers to bring into your home. Very floriferous, Manhattan Island offers tons of color from early summer to fall. Give it full sun, and keep the soil moist, and you will truly be amazed at this exceptional flower.
