cold high-desert crop
Haskap
Lonicera caerulea
An extremely cold-hardy, early-ripening berry suited to cold plateaus and short-season high-desert environments.
Data: preliminaryBiome fit
Hot high desert
Extreme heat and long hot seasons conflict with productive cultivation.
Confidence: high
Hot/cold high desert
Only cooler microclimates or heat-adapted selections are plausible.
Confidence: medium
Cold plateau
Exceptional winter and flower hardiness align with short cold seasons.
Confidence: high
Alpine / short season
Very early ripening and frost-tolerant flowers address the main alpine constraints.
Confidence: high
Planning profile
| Lifecycle | Perennial |
|---|---|
| Harvested part | fruit |
| Productive winter minimum | -50°F |
| Routine summer maximum | 90°F |
| Annual irrigation | 1.0–1.5 acre-feet/acre |
| Mature yield | 8000–10000 lb/acre |
| Representative density | 1360 plants/acre |
Planning values describe productive plantings, not absolute survival limits. Local evapotranspiration, soil, cultivar, plant age, rainfall, and management can materially change them.
Seasonal mature-plant water
| Season | Daily-equivalent gallons per plant |
|---|---|
| Spring | 2–3 |
| Summer | 3–4.5 |
| Fall | 1–2 |
Daily-equivalent demand is useful for system sizing; actual irrigation may be accumulated into less-frequent, deeper applications.
Potential products
- fresh berries
- preserves
- juice
- dried fruit
Drought and fire resilience
| Drought tolerance | Low Haskap is not drought tolerant and needs consistently moist soil during active growth. |
|---|---|
| Fire resistance | Unknown No fire-resistance finding is recorded in the current research set. |
Why it belongs
Haskap combines extreme winter hardiness, frost-tolerant flowers, and very early fruit. Those traits directly address the short-season constraints of Mammoth- and Alturas-type environments. It needs dependable moisture, so its value lies in fitting a cold, short irrigation season rather than being xeric.
Trial priorities
- Confirm irrigation demand under cold high-desert evapotranspiration conditions.
- Compare flowering, frost survival, harvest date, and fruit quality by cultivar.
- Select for tolerance of stronger summer heat and lower humidity.
