Fast-growing tropical herbaceous plant (not a true tree) that fruits within 10-12 months from seed. In Australia, 'papaya' refers to red/orange-fleshed varieties and 'pawpaw' to yellow-fleshed types - both are Carica papaya. Strictly tropical/warm subtropical. Frost kills them outright. Extremely productive when conditions are right - a single plant can produce 30-50 fruit per year. Short-lived (3-5 years productive life) but easily replaced from seed.
