What is Alyssum?

Alyssum is a genus of flowering plants in the family Brassicaceae, which also includes mustard, cabbage, and broccoli. The name "alyssum" comes from the Greek word "alysson," which means "curing madness," as the plant was once thought to have medicinal properties. Today, alyssum is prized primarily for its ornamental value, with its delicate blooms and sweet scent making it a popular choice for borders, containers, and hanging baskets.

Varieties of Alyssum

There are several varieties of alyssum available, each with its own unique characteristics and growing requirements. Some of the most popular types include:

• Sweet alyssum (Lobularia maritima): This is the most commonly grown variety of alyssum, known for its profusion of tiny white, pink, or lavender flowers and low-growing habit. It is often used as a filler plant in sunny borders or as a groundcover in between larger perennials.
• Yellow alyssum (Aurinia saxatilis): As the name suggests, this variety produces bright yellow flowers that add a splash of color to any garden. It is a bit taller than sweet alyssum, reaching up to 12 inches in height.
• Purple alyssum (Alyssum montanum): This type of alyssum has lavender-purple flowers and a slightly taller habit than sweet alyssum, growing up to 18 inches tall. It is a good choice for rock gardens or other areas with well-drained soil.

Growing Alyssum

One of the great things about alyssum is how easy it is to grow. Here are some tips to help you get started:

Planting Alyssum

Alyssum can be grown from seed or purchased as transplants. If you're starting from seed, sow them indoors in late winter or early spring, then transplant them outside after the last frost. For best results, choose a sunny location with well-drained soil. If your soil is heavy or clay-like, consider adding some sand or perlite to improve drainage.

Watering Alyssum

Alyssum prefers evenly moist soil but will tolerate some drought once established. Water regularly during dry periods, being careful not to overwater and cause root rot.

Fertilizing Alyssum

Alyssum doesn't require much fertilizer, but you can apply a balanced, slow-release fertilizer once or twice a season if desired.

Maintaining Alyssum

Deadhead spent blooms regularly to encourage new growth and maintain the plant's shape. Alyssum may become leggy or sparse over time; if this happens, trim the plant back by one-third to encourage bushier growth. In colder climates, alyssum may die back in winter but should regrow in spring.

Using Alyssum in Your Garden

Alyssum is a versatile plant that can be used in a variety of ways in your garden. Here are some ideas to inspire you:

Border Plantings

Alyssum makes an excellent border plant, creating a soft, romantic edge around beds and pathways. Try pairing it with other low-growing annuals like pansies or violas for a colorful display.

Containers

Alyssum does well in containers of all kinds, from hanging baskets to window boxes. Mix it with other trailing plants like ivy or petunias for a cascading effect.

Rock Gardens

The low-growing habit of alyssum makes it a natural choice for rock gardens or other areas with well-drained soil. Pair it with other alpine plants like sedums or sempervivums for a beautiful display.

Cut Flowers

Alyssum's fragrant blooms make it a lovely addition to bouquets and floral arrangements. Cut stems early in the morning before the heat of the day to ensure the longest vase life.

Alyssum Pests and Diseases

While alyssum is generally a hardy and disease-resistant plant, it can sometimes fall prey to certain pests and problems. Here are some to watch out for:

Aphids

Aphids are small, sap-sucking insects that can cause stunted growth and yellowing leaves. To control them, spray the plant with a strong stream of water or use insecticidal soap.

Slugs and Snails

Slugs and snails love to munch on the tender leaves and stems of alyssum. Use slug bait or set out beer traps to keep them at bay.

Fungal Diseases

Alyssum can be susceptible to fungal diseases like powdery mildew and downy mildew. To prevent these problems, avoid overcrowding plants and water in the morning to allow the leaves to dry out during the day. If necessary, treat the plant with a fungicide according to package instructions.
