About Dahlia Tubers (Collarette) - Rhubarb & Custard

Dahlia

Seed Type Tuber
Plant Type Collarette

We fell in love with this striking collarette dahlia! Rhubarb & Custard Dahlia features a cheery golden center surrounded by creamy custard-yellow petals boldly brushed with deep rhubarb raspberry-red. Good enough to eat, the contrast of warm and cool tones gives each bloom a delicious, dessert-like appeal that brightens the garden bed. It produces a profusion of three inch blooms from midsummer through frost.
