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.

Containers / Before plantingUse a lighter container medium instead of dense garden soil in pots and grow bags.
- View
Organic mulch
Soil / After plantingHold soil moisture, suppress weeds, moderate soil temperature, and protect shallow roots.

Yield curve
Estimated Pound Return
Projected annual yield ramp from establishment to full production, using the current sourced range for Stella Supreme daylily.
- Year 1
- 0 lb Establishment year: focus on roots before harvest.
- Year 5
- 17.1-25.7 lb
- Year 10
- 60-90 lb
- 10-year total
- 243.4-365.1 lb/10 yrs
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: Plant 0-1 in deep
- 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: full, partial light, loam, clay soil, and medium water.
- Use 20-25 ft in-row x 25-30 ft rows as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 15-30 ft H x 15-25 ft W.
- Native-plant cues are starting points; confirm regional nativity, straight-species versus cultivar status, and local invasive 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.
