Planting Strategy
- Planting depth: Set the crown at the same level it grew in the nursery pot.
- Container minimum: 2+ gal (good). Use 2+ gal per plant, or wider mixed containers with similar water needs.
- Start with one plant when testing fit in a new bed or container.
Risk Factors
- Match the site first: partial light, loam, clay soil, and high water.
- Use 1-3 ft apart as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 1-4 ft H x 1-3 ft W.
- Local drainage, pests, chill hours, wildlife pressure, and microclimates can change the result.

Sources & Methodology
This guide combines hardiness range, light, soil, water, harvest timing, traits, supplier links, plant relationships, and quantitative planning metrics. Pairings are screened for practical garden fit.
Quantitative values use extension and botanical-reference ranges where available. For less-studied cultivars, similar crops fill gaps conservatively. Ranges are intentionally broad so the profile stays useful without pretending to be exact.
