Introducing Coseytown Tallboy. This dapper gent can rock a white tux like no one you’ve ever seen all while keeping his cool when the heat is on! It’s time to tackle the dog days of summer with a tall drink of Coseytown Tallboy!

As his name suggests, Coseytown Tallboy is no short guy. No need to feel intimidated by this 6’ tall gentleman though - we’re confident he’ll become the white dahlia you go steady with. Pinching and continual harvest keep plant height well managed while he continues to work for you, pumping out the blooms. 4” fully double blooms with high petal count are supported by slender yet strong stems above the leaf canopy. These stems have integrity! It is common to harvest 20” stems without a negative effect to plant growth or subsequent bloom flushes.

But the quality that really puts Coseytown Tallboy head and shoulders above his peers is his sensitivity to your needs a cut flower grower - standing up to the heat in the dog days of summer and continuing to produce marketable white blooms that resist burning despite high humidity, full sun, multi-day 100F weather here in the mid-Atlantic. He’s no summer fling either, continuing the romance into the fall and maintaining his closed center until frost. How about long-term commitment? Coseytown Tallboy isn’t afraid – he’ll be happy to produce ample, high yielding eyed tubers for many seasons to come.

LeeAnn's Hybridizer Notes - CT™ Tallboy

Early on in his journey through the Coseytown Cut Flower dahlia hybridization program, CT Tallboy quickly set himself apart from his seedling peers when I was in desperate need of white blooms during an extended summer heat wave. It was then I noticed the quality of the blooms being produced when other dahlias had wilted - and rightfully so. I wilt under intense heat!

But CT Tallboy’s seasonal resilience, notably withstanding a higher heat index than his dahlia peers quickly secured him a spot in the propagation line up. As always, keep your plants well hydrated during prolonged high heat events and avoid getting the buds and blooms wet; good management lets your superstars reach even higher! Pair CT Tallboy up with CT Early Girl in your cut flower program for the ultimate supercouple to get your season started off good and early and keep it going long and strong.

Thank you for your interest in our original Coseytown dahlia creations!

Our cut flower breeding program has been shaped by our own experiences and frustrations as a cut flower farm in search of the best dahlia varieties to bring maximum impact to our operation and bottom line... and our enjoyment as dahlia enthusiasts too!
