Absolutely beautiful pink blooms. I didn't plant (have) enough seeds to produce a huge vine. of 7 or 8 seeds, maybe 4 or 5 took off, so the vine looks anorexic but still produces 4-6 large pink blooms a day, I started seeds indoors late March/early April. Planted in June and blooms came early Aug.
will add photo soon.
