Many gardeners turn to Sweet Alyssum for early spring color, and Dark Knight™ Sweet Alyssum can certainly fit the bill for brightening the dull days before most flowers begin their bloom. However, this variety will bloom all summer, which sets it far apart from the pack. The sweetly fragrant flowers are a deep shade of purple that pops against the medium-green foliage. Bees and butterflies flock to the masses of ever-blooming flowers, as well. and Dark Knight™ Sweet Alyssum is a hardy annual that blooms until the first hard frost, so they provide the fall interest that is much-needed in most gardens and containers.

You can expect your Sweet Alyssum to be a dependable trailing “spiller” in your container plantings. They can trail up to 24” in a container. Plus, they offer a constant show of color when planted in the garden as an annual border plant or groundcover. Both cold- and heat-tolerant, you’ll notice that your Dark Knight™ Sweet Alyssum is a dependable bloomer from early spring until fall. If you have a sunny space in need of color, give this beauty a try.

Dark Knight Sweet Alyssum Care

Dark Knight™ Sweet Alyssum doesn’t require deadheading and can withstand a variety of spring, summer and fall temperatures. However, it does require regular watering. Because of its water needs, try planting in a larger planter that will not dry out as quickly as a smaller one. Maximize container performance with regular applications of a balanced, water-soluble fertilizer starting in mid-summer. An annual application of compost or fertilizer will do for Sweet Alyssum planted in garden beds.

Dark Knight Sweet Alyssum Spacing

Opt for larger containers for your Sweet Alyssum to ensure maximum water retention. Container plant spacing should be 6 to 8”. When using as an annual groundcover or border plant, allow for 12-18” of space between plants.

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. Hungry animals, drought, poor soil conditions, over watering, diseases & pests are all good examples of what can cause plants to die. The Plant Addicts Warranty is a 1 year warranty protecting you from all of the unknowns and will replace your plant if something were to happen to it.

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). We may ask for photos for documentation purposes, but we try to make the process as easy as possible.

Guarantee and Warranty

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.
