Hakonechloa
Hakonechloa macra
Hakonechloa macra is a graceful, arching ornamental grass prized for its cascading, bamboo-like foliage. It is a perennial grass that typically grows in clumps, forming a soft, flowing mound. Native to moist woodland areas, it prefers shade and well-drained soil. It's primarily an outdoor plant, adding texture and movement to gardens. While it can be grown in containers, it will not thrive indoors long-term. People grow it for its elegant form, unique texture, and ability to brighten shady areas.
Sweet Alyssum
Lobularia maritima
Sweet Alyssum is a low-growing, flowering annual (or short-lived perennial in warmer climates) known for its profuse clusters of tiny, fragrant flowers. It typically grows 4-12 inches tall and spreads 6-18 inches wide. The flowers are commonly white, but cultivars offer shades of pink, purple, and lavender. It's primarily an outdoor plant, valued for its ability to attract pollinators and its use in borders, rock gardens, and containers. While it can be brought indoors, it requires very bright light and cool temperatures to thrive.

Sweet Alyssum thrives in full sun, requiring at least six hours of direct sunlight daily. However, it can also tolerate partial shade, especially in hotter climates where intense afternoon sun can scorch the foliage. When planting Sweet Alyssum, choose a location that receives ample sunlight throughout the day. In indoor settings, place the plant near a sunny window or supplement with grow lights if natural light is insufficient. Insufficient light can lead to leggy growth and reduced blooming. Rotate the plant regularly to ensure even light exposure on all sides. Monitor the plant for signs of light stress, such as pale leaves or stretching stems, and adjust its position accordingly.
How do I care for Sweet Alyssum?
Sweet Alyssum thrives in full sun to partial shade, requiring at least six hours of sunlight daily for optimal blooming. It prefers well-drained soil with a slightly acidic to neutral pH. Water regularly, especially during dry periods, but avoid overwatering, which can lead to root rot. Fertilize every 2-3 weeks with a balanced fertilizer to promote continuous blooming. Deadhead spent flowers to encourage new growth and maintain a tidy appearance. Prune back leggy growth to maintain a compact shape. Sweet Alyssum is relatively low-maintenance, but regular care will ensure vibrant blooms and healthy growth. Protect from frost in colder climates, as it is an annual in most regions. Mulching helps retain moisture and suppress weeds.
How do I propagate Sweet Alyssum?
Sweet Alyssum can be propagated by seed, stem cuttings, or division. To propagate by seed, sow seeds indoors 6-8 weeks before the last frost or direct sow after the danger of frost has passed. For stem cuttings, take 4-6 inch cuttings from healthy stems and root them in water or moist potting mix. To propagate by division, carefully divide established plants in the spring or fall, ensuring each division has healthy roots and foliage. Plant the divisions in well-drained soil and water thoroughly. Keep the soil consistently moist until new growth appears. Provide adequate sunlight and fertilize regularly to promote healthy growth. These methods are relatively simple and can produce new plants quickly.
