Fountain Grass
Pennisetum setaceum
Fountain Grass is a perennial grass known for its graceful, arching foliage and bottlebrush-like flower plumes. Typically grown as an ornamental grass, it adds texture and movement to landscapes. It forms dense clumps of slender, linear leaves that can range in color from green to reddish-purple, depending on the cultivar. The feathery flower plumes emerge in summer and persist into fall, adding visual interest. While primarily an outdoor plant, it is sometimes grown in containers. It is valued for its drought tolerance and low maintenance requirements in suitable climates.
Mourning Bride
Scabiosa atropurpurea
Scabiosa atropurpurea, commonly known as Mourning Bride, is an annual or short-lived perennial flowering plant. It's characterized by its distinctive, dome-shaped flower heads resembling pincushions, available in shades of deep burgundy, purple, pink, and white. Typically grown outdoors in gardens and borders, it reaches heights of 60-90 cm. People cultivate it for its attractive flowers, which are excellent for cutting and attracting pollinators like bees and butterflies.

❓ Frequently Asked Questions — Comparing These Plants
Fountain Grass
What are the light requirements for Fountain Grass?
Fountain Grass requires a minimum of six hours of direct sunlight each day to thrive and produce abundant blooms. Insufficient light can lead to weak growth, fewer flowers, and a generally unhealthy appearance. When planting Fountain Grass, choose a location that receives full sun exposure throughout the day.
How do I care for Fountain Grass?
Fountain Grass thrives in full sun and well-drained soil. Water deeply but infrequently, allowing the soil to dry out slightly between waterings. Fertilize in spring with a balanced fertilizer to promote healthy growth and abundant blooms. Prune back dead foliage in late winter or early spring before new growth emerges.
How do I propagate Fountain Grass?
Fountain Grass is easily propagated by division. In early spring, carefully dig up the clump and divide it into smaller sections, ensuring each section has healthy roots and foliage. Replant the divisions in well-drained soil and water thoroughly. Stem cuttings are not a reliable method. Keikis do not naturally occur on Fountain Grass.
Mourning Bride
What are the light requirements for Mourning Bride?
Mourning Bride thrives in full sun, requiring a minimum of 6 hours of direct sunlight each day. Insufficient light can lead to leggy growth, reduced flowering, and pale foliage. When grown indoors, place your Mourning Bride near a south-facing window where it can receive the most intense sunlight. If natural light is limited, supplement with grow lights to ensure adequate illumination.
How do I care for Mourning Bride?
Mourning Bride requires well-draining soil, ideally a loamy mix amended with compost. Water thoroughly when the top inch of soil feels dry, avoiding overwatering, which can lead to root rot. Provide at least 6 hours of direct sunlight daily for optimal blooming. Fertilize every 2-3 weeks during the growing season with a balanced, water-soluble fertilizer, switching to a fertilizer higher in phosphorus to encourage more blooms.
How do I propagate Mourning Bride?
Mourning Bride can be propagated by seed or stem cuttings. For seeds, sow them indoors 6-8 weeks before the last frost. Keep the soil moist and provide warmth until germination. For stem cuttings, take 4-6 inch cuttings from healthy stems. Remove the lower leaves and dip the cut end in rooting hormone. Plant the cutting in well-draining soil and keep it moist until roots develop, which usually takes a few weeks. Keep cuttings in bright, indirect light during rooting. Transplant established cuttings into individual pots. Division is not typically used for Mourning Bride as it’s a tap-rooted plant. Keiki propagation is not applicable to this plant.
