An armload of Dahlia Buttercup

Dahlia ‘Buttercup’

Description

Clear, cheerful yellow blooms look like glowing orbs on the tips of the stems. Foliage is a contrasting dark green, and vigorous plants are very productive.

Details

Form: pompon
Bloom size: up to 2 in
Site: full sun
Days to maturity: 80 to 100 days
Plant spacing: 12 to 18 in
Pinch: when 12 in tall

Harvesting/Vase Life

Dahlias don’t unfurl much once they’ve been harvested so it’s important to not pick them too early. Harvest when blooms are three-quarters of the way open, but not overly ripe. Check the back of each flower head, looking for firm and lush petals versus papery or slightly dehydrated ones. Place into water with hydrator, or sear stem ends by placing into 160°F to 180°F (just off boiling) water and allow to cool for one hour. Expect a vase life of 5 days.
