Physalis peruviana
Peruvian groundcherry, physalis, Cape gooseberry, Peruvian love-in-a-cage, uchuva: this is the physalis grown for its fruit, whose small, golden, sweet and slightly tangy berry can be enjoyed just as it is. Do not confuse it with the Chinese lantern, its strictly ornamental cousin: here, the papery calyx is simply natural packaging that protects the fruit and ensures its long shelf life.
Characteristics:
-
Sweet fruit: golden berries the size of a cherry, with a unique flavor somewhere between pineapple and redcurrant, protected by their lantern-like husk.
-
Generous production: a single well-managed plant can produce dozens of fruits from August until the first frosts.
-
Long shelf life: in their intact calyx, the fruits keep for several weeks at room temperature.
Precautions:
- Only eat perfectly ripe fruits, when the calyx has turned beige and papery and the berry is deep golden. Green fruits and foliage should not be eaten.
- Frost-tender plant: native to the tropical Andes, it is killed by frost and is grown as an annual in our climates, or in a pot that can be overwintered frost-free.
Sowing advice:
-
Position: full sun and warmth, essential for the fruit to ripen.
-
Soil: rich, loose, moist and well drained. It is a hungry plant, like the tomato to which it is related: adding compost will genuinely benefit it. However, avoid overfertilizing with nitrogen, or you risk producing lots of foliage and few fruits.
-
Method: no cold stratification — this tropical species requires warmth instead. Sow in pots under cover from February to March at 20-25 °C, covering lightly, then transplant after the last frosts. See how to sow seeds.
Planting advice:
- Transplant after the frosts, spacing plants 80 cm to 1 m apart: the plant becomes very large and spreading. Provide a stake or support.
Care advice:
- Water regularly at the base in summer. Mulch to retain moisture in the soil.
- Pinch out the main stems to encourage branching and therefore fruit production.
Harvesting advice:
- The sure sign: ripe fruits fall to the ground by themselves, inside their calyx, which has turned beige and dry. Simply gather them at the base of the plant.
Beneficial companions:
Benefits for biodiversity:
- Its yellow flowers speckled with brown, discreet but numerous, are visited by bees and bumblebees all summer.
- Its long fruiting period, lasting until the frosts, extends the garden's food resources into late season.
Uses:
- Delicious fruits eaten raw, in jam, in pies or dipped in chocolate. Their calyx, opening into a corolla, also makes a spectacular garnish for desserts.
Harvesting your own seeds:
Crush a few very ripe fruits in a little water, leave them to ferment for two to three days, then rinse them: the healthy seeds sink to the bottom while the debris floats. Dry them on paper before storing. See storing your seeds.
