About
Cardinal flower is the hummingbird magnet of wet ditches—scarlet spikes, lance leaves, and a love language written in milliliters of nectar per minute. Short-lived as individual plants in some settings but seeds in like it owes you rent. Native in northern counties; central/south populations exist in appropriate wetlands. Give it moisture and some midday shade inland. ☀️💧 Sun and Water Requirements: Sun to part shade. Consistent soil moisture—pond edge, rain garden, or soaker zone. Mulch keeps roots cool. ✂️ Propagation: Seeds (tiny, surface sow); division of basal rosettes in cool seasons. 🌾 Harvest / Best Use Timing: Leave spikes for hummingbirds unless ethics and local rules cover cut-flower harvest; seeds ripen for collection if you are expanding plantings.
Permaculture Functions
- Pollinator: Scarlet tubes pump nectar for hummingbirds and draw smaller pollinators during bloom.
- Wildlife Attractor: Hummingbird and butterfly support along wet edges and rain gardens.
- Ornamental: Riparian beauty and rain-garden architecture where standing water is not mandatory but wet feet are.
Practitioner Notes
- Basal rosette in year one, tall bloom in year two is common—do not toss “non-blooming babies” the first season.
- Hummingbirds treat red tubes like fuel stations—cluster a few plants so territorial birds do not defend a singleton to death.
- Mulch crowns lightly in zone 3-6 winters—freeze-thaw heaving kills more than cold depth alone.
- Self-sows only where soil stays damp—dry shade gives you zero volunteers no matter how much seed you shake.
Companion Planting
- Pickerelweed
- Swamp milkweed
- Joe Pye weed
- Dry berms
- Deep shade that prevents bloom
