BROCADE - VANCOUVER This plant has a patent - Propagation of this plant for resale is illegal.... We buy in starters from and authorized Grower Zonal Geraniums are Stronger than seeded Geraniums... They last longer - can handle the heat better than seeded geraniums... They grow much taller.. Main difference to see if you have seeded geranium VS Zonal geranium... On a Zonal the blossoms will not easily fall off with overhead watering - Seeded ones the petals of the blooms will fall off with the slightest touch of water on the blossom heads... Hence Zonals are much more showy Geraniums are GREAT in planters.
