Estimated Pound Return
Projected annual yield ramp from establishment to full production, using the current sourced range for Ichiban eggplant.

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 the same depth as the nursery pot.
- Container minimum: 5+ gal (good). Use one plant per 5+ gal container.
- 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.
- Use the pairing map below to choose nearby companions or compatible varieties.
Risk Factors
- Match the site first: full light, loam soil, and medium water.
- Use 2 ft in-row x 3 ft rows as the first spacing model; adjust for hedges, trellises, containers, or local guidance.
- Plan around mature size: 2-4 ft H x 2-3 ft W.
- For harvest planning, treat "slender fruits in summer" and 4-7 lb/plant/season as planning ranges, not guarantees.
- Avoid planting this close to black walnut roots unless local guidance says the cultivar is tolerant.

Companion Plants & Pairings
Plant Nearby
Peppers and eggplants share tomato-like growing conditions and pair cleanly with nearby flowering or aromatic companions in mixed beds.
Use it: Keep companions low and off the pepper crown; use them as edge plants or alternating pockets rather than a dense understory.
Warm-season vegetables benefit from nearby flower strips that keep bloom and insect activity close to the crop bed.
Use it: Use a narrow flower strip along the vegetable bed edge so beneficial insects are nearby without reducing crop spacing.
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.
