What customers say
Customers highly praise the 'Thomas Edison' dahlia for its stunning aesthetic impact. The primary draw is the impressive dinnerplate size and the deep, velvety purple color, which often appears richer than expected. Successful growers find the blooms luxurious and worth the investment, noting the plant is a vigorous and prolific bloomer late in the season. The overall satisfaction is high due to this spectacular performance. However, a recurring concern involves the initial quality of the tubers. While many receive healthy stock that sprouts quickly, some buyers report tubers arriving dry or failing to grow, causing frustration given the premium cost. This variability in initial tuber viability is the main point of inconsistency in the customer experience.
