Pound return is the stock-style yield metric. These are planning ranges for comparing plants, not guarantees. Cultivar, rootstock, climate, soil, pruning, pest pressure, and wildlife can move actual results.

Shaded band shows the sourced low-to-high pound-yield range. The line tracks the midpoint for quick comparison.
Method: direct pound yield from crop metric source. Annual crops assume one comparable planting per year; perennial crops ramp from first bearing to full production.
Planting Strategy
- Planting depth: Set transplants at nursery depth or follow seed-packet depth for direct sowing.
- Container minimum: 5+ gal (workable). Use 5+ gal for most single vegetable plants; smaller leafy/root crops can use less.
- Start with one plant when testing fit in a new bed or container.
- Plant more than one when harvest volume or pollination is the main goal.
Risk Factors
- Match the site first: full, partial light, loam, clay soil, and medium water.
- Use 0.5-1.5 ft in-row x 1-3 ft rows as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 0.8-3 ft H x 0.8-2 ft W.
- For harvest planning, treat "purple-red mustard leaves" and 0.5-1.5 lb/plant/season as planning ranges, not guarantees.
- 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.
