- 28 in
- Container
- 10+ gal · 22+ in deep
01 · Light & site
Give it the light its growth depends on.
Full sun, with roughly 6 to 8 hours of useful light. Perennial timing, dormancy, and winter survival are climate- and cultivar-specific.
02 · Water & soil
Keep roots supplied without trapping water.
Water deeply when the active root zone begins to dry.
- Soil
- Loose, organic, species-appropriate garden soil
- Drainage
- Well drained
- pH
- Species-specific; verify the grower label and linked guidance
03 · Spacing & roots
Make room for the mature plant.
Space plants about 28 inches apart. Expect a mature plant around 89 inches tall by 28 inches wide.
deep, clumping, fibrous, taprooted, or rhizomatous species-specific root system. Container figures are a planning floor, not a claim that long-term container culture is ideal.
04 · Start
Begin with the method that protects establishment.
Use the species-appropriate method—seed, cutting, division, bulb, tuber, or a healthy transplant—and follow the plant label for timing.
05 · Care
Support healthy growth through the season.
Usually self-supporting in a compatible plant community. Add a discreet stake only if wind, bloom weight, or an exposed site makes it necessary.

06 · Flower or harvest
Flowering and wildlife value
180–730 days to the first expected harvest, bloom, or established display; perennials may need additional seasons to settle. Bloom timing and establishment vary with climate, plant provenance, and the exact species or cultivar; locally appropriate stock is the best reference.
07 · Safety
Know the cautions before you place or use it.
- Use legally nursery-propagated stock and do not collect from wild populations.
