Companion Planting
For Dyschoriste humistrata (Swamp Twinflower / Spreading Snakeherb), companions work best when they share similar light needs, tolerate Florida heat, and extend nectar and color through the season. Use taller plants behind it and keep aggressive spreaders trimmed so the Twinflower can maintain coverage.
Blanket Flower (Gaillardia pulchella)
Benefits: Bright orange and red blooms add strong contrast and attract pollinators.
Use:
- Plant along sunny edges where you want steady butterfly activity.
- Use in drifts to create a wildflower-meadow look.
Lanceleaf Coreopsis (Coreopsis lanceolata)
Benefits: Golden blooms complement violet flowers and support butterflies and bees.
Use:
- Mix through the bed to brighten the planting and extend bloom interest.
- Use as a border plant behind or beside the Twinflower patches.
Pink Muhly Grass (Muhlenbergia capillaris)
Benefits: Fine texture and fall color create a soft backdrop and seasonal movement.
Use:
- Plant behind Twinflower for a layered effect with varied textures.
- Use in small clumps to frame pollinator pockets.
Black-eyed Susan (Rudbeckia hirta)
Benefits: Cheerful yellow blooms attract butterflies and can draw birds later with seed heads.
Use:
- Place toward the back of the bed for height and visibility.
- Use in wildlife-friendly areas to build seasonal habitat.
Tropical Sage (Salvia coccinea)
Benefits: Red blooms attract hummingbirds and butterflies, adding strong color contrast.
Use:
- Interplant in pockets to keep nectar sources steady.
- Use behind Twinflower for a layered, pollinator-forward border.
Lantana (Lantana camara)
Benefits: Drought-tough, long-blooming, and a strong pollinator attractor.
Use:
- Use as an edge or corner anchor near Twinflower patches.
- Keep pruned so it does not shade the groundcover.
Blue Porterweed (Stachytarpheta jamaicensis)
Benefits: Reliable butterfly plant that complements the Twinflower’s pollinator value.
Use:
- Plant along paths or bed fronts to pull pollinator traffic through the area.
- Use as a consistent “nectar station” near the groundcover.
Tall Verbena (Verbena bonariensis)
Benefits: Airy, vertical blooms add height and attract butterflies without dense shade.
Use:
- Place behind Twinflower for vertical interest and bloom layering.
- Use to soften the transition between low groundcovers and taller plants.
