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).

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die.

The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability).

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
