Description
Royal Carpet Alyssum is a well-known blossoming flower for its short height, bright purple hue, and fragrant aroma. It is easy to grow and looks great in the garden border, containers and walkways. This species is an All-America Selections winner for orchid-like beauty and high yield.
Eye-Catching Purple Blooms
Royal Carpet Alyssum produces small clusters of bright violet-purple blooms. In spring and fall, flowers bloom one after the other. The plants are low-growing and wide-spreading, making a bright splash across any garden. Each blossom is tiny and approx. ½” but together they make a bold statement.
Sweet Fragrance That Attracts Pollinators
The flowers themselves emit a mild honey scent, which draws bees, butterflies and other beneficial bugs. This also makes Royal Carpet an excellent selection to be used in pollinator gardens. Its scented foliage also makes it attractive as a plant near walkways and patios that will give off a pleasing fragrance.
Compact and Spreading Growth
This plant grows about 3 to 6 inches tall and spreads 5 to 10 inches wide. It stays low to the ground and fills empty garden spaces quickly. It’s perfect for edging flower beds, filling gaps in rock gardens, and decorating the edges of pots and containers.
Easy to Grow and Maintain
Royal Carpet Alyssum is easy to grow in full sun or light shade. It grows best in well-drained soil and needs regular moisture during the germination stage. Once established, it can handle some dry weather. It may even reseed itself and return next year in warmer climates.
Planting Instructions
Here are a few easy steps to follow for the best effect:
- Direct sow seeds outdoors after the last frost. To get earlier blooms, start seedlings indoors 4–6 weeks before the last frost.
- Scatter seeds over the surface of the soil, then press lightly. Do not cover too deeply as seeds require light for germination.
- Germination takes 8–10 days on average.
- Plant seeds 1 inch apart. Once seedlings have grown, thin them to 6 to 8 inches apart for improved air circulation and healthier plants.
- Water the soil during germination. Water consistently once settled down, but do not overwater.
Light and Soil Needs
Royal Carpet Alyssum grows best in full sun but will tolerate light shade. It likes loose, dryish soil and performs best in average garden loam. Fertilizer is not necessary, but a light feeding in containers might produce extra blooms.
Seasonal Care Tips
Keep it blooming with simple care by following these steps:
- Deadheading: Clip off old flowers to make way for new blooms.
- Shearing: Trim back in mid summer to control spreading and to stimulate new growth.
- Re-seeding: Let a few flowers go to seed if you want them to return next year.
- Storage: If saving the seeds, dry them and, once dried, store them in a cool, dry place. The seeds may be damaged by heat and moisture.
Applications
Royal Carpet Alyssum does well in most locations:
- Garden borders and edges
- Window boxes and patio pots
- Rock gardens and gravel paths
- Hanging baskets and containers
- Between stepping stones or walkways
Its spreading growth is ideal for covering soil and offering color in hard-to-decorate spots.
