Burpee Alyssum Seeds

While you can start them indoors, Alyssum is best sown directly into the garden or container where you want them to grow. They establish quickly and often resent being transplanted, so direct sowing is the most reliable method.

Since these have a mature spread of 5 to 8 inches, you should space your seeds or seedlings about 6 inches apart. This allows them to fill in nicely for a continuous, carpet-like look without overcrowding.

Alyssum is a reliable bloomer, but it can sometimes slow down during the peak heat of mid-summer. If you notice flowering tapering off, give the plants a light trim to encourage a fresh flush of blooms as the weather cools.

Yes, their prostrate, low-growing habit makes them an excellent choice for hanging baskets and window boxes. They will spill gracefully over the edges, creating a soft, fragrant, and white-flowered border.

Deadheading isn't strictly necessary for Alyssum, but it can help keep the plants looking tidy. If they start to look a bit leggy or sparse, shearing them back by an inch or two will stimulate new growth and more flowers.
