    Features

    Good looks AND personality.

    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.

    Maintenance Notes: 

    No deadheading necessary for continuous bloom.

    It is cold tolerant and heat tolerant. He is also a "heavy drinker" and will prefer evenly moist soil. It will be quick to show drought stress, but should bounce back quickly once re-hydrated. In a hanging basket you should be prepared to water often, maybe more than once a day during warm weather. Plants are easier to keep moist when planted in large planters. Due to water needs it is ideal for use in larger planters. In containers an application of continuous release fertilizer at planting is best. To help maximize performance use applications of a well-balanced water-soluble fertilizer (according to package directions) starting in mid-summer.

    It will also perform well in the landscape where it will function as an annual, full sun, groundcover.

    While plants shouldn't need to be trimmed back, if the plant is taking over your walkway or is looking less than the best a trim can be administered at anytime. Use a sharp pair of scissors or pruning shears as needed.

    A yearly application of fertilizer or compost on garden beds and regular fertilization of plants in pots will help ensure the best possible performance.
