Dahlia Dinnerplate Thomas Edison
Best choice for gardeners wanting dramatic, long-lasting floral arrangements.
This heirloom dahlia is the ultimate showstopper for late-season color, delivering massive, plum-purple blooms that demand attention. While these heavy, dinnerplate-sized flowers require a bit of staking to keep them upright, the trade-off is a dramatic, pollinator-friendly display that remains unmatched for fresh-cut arrangements.
