Our Rainbow Open Form Mix is full of an array of colours and petal forms of collarette and anemone dahlias from our cutting garden! Grow your own rainbow for beautiful dahlia bouquets all summer long.
Each seed produces a unique dahlia plant and tubers can be saved from each at the end of the first growing season.
Here at Nested we start our dahlia seeds 4 - 5 weeks prior to planting out. We watch for when the lilacs start to bloom as our signal for when to plant out our dahlia seedlings.
