If it spreads greater than you need, edge or spade off the outer runners and replant divisions elsewhere.
Propagation
Division: Elevate and cut up clumps in early spring.
Cuttings: Softwood cuttings root simply in heat climate.
Pests and notes
Usually low pest strain.
Aphids are regular on close by milkweed and are largely beauty. They don’t hassle Monarch or Queen caterpillars. Don’t spray. Caterpillar eggs are tiny and simple to dislodge, and efforts to make milkweed aphid-free may cause hurt.
Design concepts and good companions
Plant mistflower between native milkweeds so adults have nectar close to larval hosts.
Pair with long-bloom nectar vegetation for steady shade:
Tithonia (Mexican sunflower) for late-summer gasoline
Zinnias for all-summer touchdown pads
Verbena and blackfoot daisy for low edging
Dalea or Buddleja marrubifolia for a drought-tough shrub backdrop
Add a puddling dish close by for minerals and a shelter shrub upwind to calm the air.
My expertise
