These are often misnamed as Geraniums but they are actually Pelargoniums. They are our bread and butter at the nursery. We grow over 20,000 a year of these, with 3 stock houses put aside for these alone. They are great plants looking fantastic in borders and pots a like. They will simply flower all summer long and right up until the first frosts if you leave them outside. They are not frost hardy (no Pelargoniums are) so will need winter protection in a frost free environment.
