(Lobularia) Looking for a new alternative to SNOW PRINCESS® Lobularia? Here we introduce to you WHITE KNIGHT®! WHITE KNIGHT® has great flower power but is not as aggressive as it sister. Lobularia are sterile therefore they put all their energy into flower production, which means nonstop color! The small white, fragrant flowers form tons of clusters that cover each plant. WHITE KNIGHT® Lobularia mixes nicely with petunias and other trailing annuals. Lobularia attracts butterflies and hummingbirds for your enjoyment! To keep your annuals looking their best, we recommend fertilizing every 2 weeks for containers and hanging baskets during the summer months.
