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.
- Use the pairing map below to choose nearby companions or compatible varieties.
Risk Factors
- Match the site first: full, partial light, loam, clay soil, and high water.
- Use 3-8 ft apart as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 3-10 ft H x 3-10 ft W.
- Plan pollination or companion context before planting; nearby varieties can matter for fruit set.
- Native-plant matches are starting points; confirm regional nativity, straight-species versus cultivar status, and local invasive guidance.

Wet-site plants can anchor rain gardens and low spots together where average garden perennials would struggle.
Use it: Group by moisture tolerance: shrubs in the wetter anchor zone, sedges at edges, and flowering perennials where water drains within a day or two.
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.
