Origin: The pepino dulce is native to the temperate Andean regions of Colombia, Peru and Chile. The plant is not known in the wild, and the details of it origin are not known. The fruit is grown commercially in New Zealand, Chile and Western Australia. The pepino dulce was being grown in San Diego before 1889 and was listed by Francisco Franceschi of Santa Barbara in 1897. Improved cultivars were imported into California from New Zealand and elsewhere in more recent times.

Adaptation: The pepino dulce is a fairly hardy plant that grows at altitudes ranging from near sea level to 10,000 ft. in its native regions. However it does best in a warm, relatively frost-free climate. The plant will survive a low temperature of 27 to 28 degrees F if the freeze is not prolonged, but may loose many of its leaves. It can be grown in many parts of central and southern California, although it does best in locations away from the coast and is not well suited for hot, interior gardens. Pepino dulce has been grown and has fruited in the milder areas of northern California (Sunset Climate Zones 16 and 17). The plant is small enough to be grown satisfactorily in a container.

DESCRIPTION

Growth Habit: Pepino dulce is a small, unarmed, herbaceous plant or bush with a woody base and fibrous roots. Growth is erect or ascending to about 3 feet high and several feet across. It is similar in these respects to a small tomato vine, and like the tomato may need staking or other support.

Foliage: The bright green leaves are sparsely covered with very small hairs. In appearance the pepino dulce is much like a potato plant, but the leaves may take many forms--simple and entire, lobed, or divided into leaflets.

Flowers: The small flowers are blue, violet-purple or white marked with purple, and are similar in form to unopened potato flowers. The pepino dulce is deemed to be parthenocarpic but a much heavier crop results from self-pollination or cross-pollination. The plants will not set fruit until the night temperatures are above 65 degrees F.

Fruit: The fruit also show considerable diversity in size and shape. In the areas of its origin there are small oblong types with many seeds, while others are pear or heart-shaped with few or many seeds. Still others are round, slightly larger than a baseball and completely seedless. The colors also vary--completely purple, solid green or green with purple stripes, or cream colored with or without purple stripes. The fruit of cultivars grown in this country are usually round to egg-shaped, about 2 to 4 inches long, with some growing up to 6 inches. The skin is typically yellow or purplish green, often with numerous darker streaks or stripes. The flesh is greenish to white and yellowish-orange. Better quality fruit is moderately sweet, refreshing and juicy with a taste and aroma similar to a combination of cantaloupe and honeydew melon. In poor varieties there can be an unpleasant "soapy" aftertaste. The fruit matures 30 to 80 days after pollination.
