Thomas Edison is a dahlia that will forever remain on my Top 10 Must Grow List. It blooms reliably all summer and can produce purple blooms up to 8” in diameter. She is a show stopper and I will forever grow it. Thomas Edison is usually about 3.5 feet in height but is very robust and bushy. My favorite thing about this dahlia: I am a sucker for purple dahlias. Thomas Edison seems to be a disease resistant dahlia that has been around for decades. It produces plenty of blooms all season long. Bloom size: large - 5” to 8” Height: Medium — 3.5’ to 4’ feet tall Tuber rating: produced an abundance of tubers that store well over winter (it seems to be a hard dahlia to kill) Year I started growing this dahlia: 2020 This listing is for one tuber or one small tuber clump, which will produce one dahlia plant.
