How to Grow & Care for Sweet Alyssum
How to Grow Sweet Alyssum
Annual species of Sweet Alyssum are usually grown from seed sown on the surface of seed trays in late winter if grown inside, or from early spring onwards if sown outside. Do not cover the Sweet Alyssum seeds, as they need light to germinate. Sweet Alyssum will readily self-seed around the garden and naturalise once you have grown it, so you won't need to do much more.
Perennial types of Sweet alyssum can be easily propagated using semi-ripe cuttings in early summer.
Take firm tip growth around 7–10cm long and place it in a pot with seed and cutting mix, or 50:50 peat and coarse propagating sand.
Remove the bottom two thirds of leaves and dip the bottom in rooting hormone.
Place in a propagator or pot covered with half of a clear 2 litre bottle, and position in partial shade. In around 6–8 weeks the cuttings should have taken root.

Sweet alyssum will thrive if you provide full sun for them. However, if you live in the region with a highly hot and dry climate, it would be better for your Sweet alyssum to get a bit of shadow in the middle of the day.
Sweet alyssum will grow in most garden soils, but prefers a well-drained fertile soil. There should be a balance between good drainage and water retention, although it is important that Sweet alyssum is kept well-watered during the summer and doesn't dry out, as this will terminate the flowering period.
Your Sweet alyssum will need 1 inch (2.5 cm) of water weekly, and even more when summer days are really hot. However, take care to provide well-drained soil for your Sweet alyssum to avoid rot of roots and stalks.
In temperate weather, gardeners may be able to grow sweet alyssum all year long, though the actual plants themselves are short-lived. Sweet alyssum plants repeat bloom, although many varieties tend to stop flowering in heat, only to often pick back up again in the fall. In areas of high humidity, compensate by reducing the amount of water given to Sweet alyssum.
Sweet alyssum grown in a well-prepared bed with rich, loamy soil will not need fertilizer. When growing your Sweet alyssum in containers, provide a light, monthly feeding using a water-soluble fertilizer.
Sweet alyssum plants do not require deadheading but can benefit from cutting them back to about half after the first flowering. This will produce a fuller plant as the season's progress.

Sweet alyssum combines nicely with many other short-statured annuals, such as shorter zinnias and marigolds, bright blue Lobelia, celosia, and snapdragons. Sweet alyssum works well as an edging plant, as an airy filler among young perennials, or as a ground cover when planted in masses. It can be overplanted among bulbs such as tulips and daffodils to fill in the area as the spring bloomers go dormant, or underplanted beneath clematis, daylilies or roses where its dense growth helps smother weeds. Sweet alyssum is especially nice placed where it can spill over the edge of a container or hanging basket, or where its billowy blooms can cascade down a slope in a rock garden. Sweet alyssum is frequently used as a filler in containers or to cascade down the planters edge.
Sweet Alyssum Companion Plants
Nemesia is a charming cool-season annual with pretty little snapdragon-shape flowers—often fragrant—that bloom in a wide range of colors. It does best in spring and fall (winter in mild-winter climates), though some varieties have better heat-tolerance than others. In cool-summer areas, such as the Pacific Northwest, nemesia will continue to bloom right through the summer into fall. Nemesia prefers moist, well-drained soil that's rich in organic matter.
Stock offers a wonderfully spicy, distinctive scent. Plant it in spring several weeks before your region's last frost date; this annual thrives in cool temperatures and stops blooming once hot weather arrives. It's especially wonderful in window boxes and planters at nose level, where its sometimes subtle effect can best be appreciated. Stock is slightly spirelike and comes in a wide range of colors. It makes a great cut flower, perfuming bouquets as well as the border. It grows best in full sun or part shade and moist, well-drained soil.
From tiny, cheerful Johnny jump-ups to the stunning 3-inch blooms of Majestic Giant pansies, the genus Viola has a spectacular array of delightful plants for the spring garden. They're must-haves to celebrate the first days of spring since they don't mind cold weather and can even take a little snow and ice. They're pretty planted in masses in the ground, but also cherished for the early color they bring to pots, window boxes, and other containers. By summer, pansies bloom less and their foliage starts to brown. It's at this time that you'll have to be tough and tear them out and replant with warm-season annuals, such as marigolds or petunias. But that's part of their charm—they are an ephemeral celebration of spring.
