Great tall phlox with brilliant colour, although I planted it in a semi-shady area and it leans toward the light. I would plant it in full sun next time.

I have two shades of this lovely perennial in my front lawn and have grown to love it. It divides easily and has bloomed faithfully for about 8 years. Mine gets about 4 ft high in full sun and the butterflys and hummingbirds love it. All places I have planted it, it has spread into pads of about 3 ft in diameter and shows no sign of slowing down. Sometimes I have cut a edge off with a shovel and given it away and no one has failed to estabish it that I have given it to. Highly recommended!

One of the best and brightest phlox cultivars. It's tuff as nails and has been a staple in my perennial garden.

'Starfire' reblooms well if it is deadheaded after the initial flush is finished.
