With its clouds of sweet-smelling, tiny white blooms, White Knight® is invaluable in containers and hanging baskets. It is a prolific bloomer from planting to frost. A newer cultivar, it holds up well to summer heat, yet is tolerant of the cool temperatures of fall. It is low growing to a height of 4-6 inches with a mounding habit. White Knight® has won awards for its top performance.

While this Lobularia hybrid doesn’t mind cold nor heat, it is not drought tolerant. It easily recovers from a dry spell, however, when hydrated. It is resistant to disease. This pollinator plant attracts bees and butterflies. Use it as a lovely ground cover in the landscape, especially along the front of a border. Grow it in a large planter that won’t dry out quickly. It is stunning with other blooms in an all-white combination container. It will trail up to 2 feet in a hanging basket.

White Knight® Sweet Alyssum Care

For pots of sweet alyssum use a continuous release fertilizer at planting. No deadheading is required, but you can trim plants back if they spread onto walkways. The plant is a heavy drinker, so water frequently – especially hanging baskets.

In the landscape, plant in average, evenly moist soil in a location that receives part sun to sun.

White Knight® Sweet Alyssum Spacing

Space it 12-18 inches. It will spread 18-24 inches, depending on where you plant it (in a container or in the ground).

    Posted by Ernie Cute on May 31st 2021

    The plants arrived dead. Had to toss them in the compost pile. Will not be purchasing these plants again.
