Planting Strategy
- Planting depth: Set the crown or top of root ball level with the surrounding soil.
- Container minimum: 10+ gal (workable). Use 10+ gal; larger containers improve moisture buffering at maturity.
- Start with one plant when testing fit in a new bed or container.
- For screening, repeat compatible plants and confirm mature spacing before buying.
Risk Factors
- Match the site first: full, partial light, loam, clay soil, and medium water.
- Use 3-8 ft apart as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 3-12 ft H x 3-10 ft W.
- For screens and hedges, confirm mature size and spacing with the nursery label or local extension guidance.
- 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, source listings, 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.
