Lobularia ‘Violet Knight®’

The Knight lobularia are wonderful multi-season plants. If hardened off, they can be planted in early spring when temperatures still fluxuate wildly, but these improved varieties also have much bettter heat performance. They aren't bulletproof plants yet, but they do bloom prolifically through the summer in most areas. Then as things cool off again in fall the plants adapt once again to wide variations in temperatures. They will bloom prolifically in fall until a good hard frost finally causes them to call it done for the year.
