Canada Mayflower (Maianthemum canadense)
Difficulty: ⭐⭐⭐⭐☆
(Slow-growing, with tricky timing and a short window for viable seed)
Seed Collection Time:
Late summer to early fall — typically August through September
Signs Seeds are Ready:
Flowers are followed by small green berries that ripen to bright red
Berries feel firm but not hard — slightly soft when gently squeezed
Inside each berry is typically 1–2 small, hard, tan seeds
Berries detach easily when gently pulled
Tip: Watch for ripe berries before wildlife removes them — birds often feed on them quickly.
Seed Collection Steps:
Collect fully red, ripe berries by hand or with snips
Gently mash berries in water to separate pulp from seeds
Rinse seeds well using a fine mesh strainer
Air-dry cleaned seeds briefly (1–2 days) before storage or stratification
Store in moist medium if not sowing immediately
Note: Seeds are tiny but durable — avoid drying them for long periods.
Germination Tips:
Requires double dormancy:
~3 months warm, then ~3 months cold stratification
Sow outdoors in fall for natural dormancy cycling
Germination may take 12–18 months — very slow to establish from seed
Seedlings are tiny and may take several years to reach blooming size
Note: For faster propagation, rhizome division is preferred — but seed is valuable for genetic diversity and restoration.
