Yellow Clover

Yellow Sweet Clover (Melilotus officinalis) – Biennial

A tall, fragrant pollinator plant with clusters of small yellow flowers that produce abundant nectar. Highly attractive to bees and valued for strong, consistent bloom in its second year.

Sowing tips:

• Depth: 5–10 mm (¼–½ inch)
• Germination: 7–14 days
• Spacing: can be sown dense, but thin if overcrowded

Coverage (dense sowing): ~20–30 sq ft per 20 g

Growing notes:

• Height: typically 3–5 ft (can grow taller in rich soil)
• Sun: full sun preferred
• Water: low to moderate; drought tolerant once established
• Soil: thrives in poor to average soils; very adaptable

Helpful info:

• Year 1: vegetative growth (low profile)
• Year 2: tall plants with heavy flowering and strong pollinator activity
• Deep roots improve soil structure and fix nitrogen
• Can self-seed if allowed to mature
• Best placed toward the back of beds due to height

General Sowing (Urban / Flowerbeds)

• Timing: Spring or early fall
• Prep: Loosen topsoil (2–5 cm), remove weeds
• Seed: Broadcast evenly and lightly cover
• Water: Keep moist until established

Tip: Expect limited blooms the first year—this plant is a long-term pollinator investment.
