Physalis pubescens: complete guide

Overview

Physalis pubescens, also known as ground-cherry, berry, or golden berry, is a tropical plant from tropical and subtropical Americas. This member of the Solanaceae family (tomato family) is known for its easy cultivation and delicious, sweet fruits. The plant is much more suitable for cooler climates than its relative, Physalis angulata.

The fruits are widely used in households for jam, compote, and fresh consumption. The decorative lantern-shaped fruits also make it an interesting ornamental plant.

Appearance and growth

Physalis pubescens is a low plant that grows only 30 to 75 centimeters tall. The plant has hairy stems (pubescens means hairy) and leaves about 5 to 10 centimeters long. The growth is compact and orderly.

The flowers are small, yellow, and grow in the leaf axils. After flowering, the characteristic lantern-shaped fruits form. These are larger than those of Physalis angulata and first green, later yellow-orange.

The berries inside are also larger - about 1 centimeter in diameter - and sweeter than those of the related species. They ripen further after picking if you leave them in the lantern.

The plant flowers and fruits abundantly from summer to fall.

Ideal location

Physalis pubescens grows well in a sunny spot but can tolerate partial shade. This makes it more suitable for cooler climates than other tropical plants. At least 5 to 6 hours of sunlight per day is ideal.

The plant stands well in a sheltered spot against walls facing south or west. It also grows well in containers on the terrace.

The plant appreciates warmth but is more robust against cooler weather than Physalis angulata.

Soil and potting

Physalis pubescens grows in normal, well-draining potting soil or garden soil. The plant is not very picky. In pots use universal potting soil mixed with 20% sand or perlite. In garden soil add compost.

The plant appreciates nutrient-rich soil and does well at pH around 6 to 7. In very poor soils add compost when planting.

Repot the next year if the plant grows in containers, or only once if the plant has become large.

Watering

Ensure the soil stays evenly moist during the growing season. The plant is drought-sensitive, so water regularly. In very dry periods water daily.

Avoid waterlogging in winter as this causes root rot. Let the soil dry out somewhat between waterings as it gets cooler.

Regular spraying with water helps on hot weather.

Feeding

Feeding promotes richer fruiting. Give balanced fertilizer (10-10-10 or similar) every 2 to 3 weeks when the plant is actively growing (May to September). No feeding in winter.

Feeding with more phosphorus (e.g. 5-10-5) in July-August helps fruit set.

The plant grows without extra feeding too, but fruiting is better with moderate feeding.

Pruning

Pruning is not essential. Pinch back excess growth if the plant becomes too full. Remove dead branches and leaves.

Early in the season (May) you can pinch off the tops to encourage more branching and thus more fruit.

Don"t remove many leaves as they provide shade to the fruits and help them ripen.

Maintenance calendar

March-April: Grow seed indoors or buy young plants. Plant outside after last frost. May-June: Plant in garden or container. Water regularly. Optional feeding. July-August: Peak flowering and fruiting. Regular water and feeding. September-October: Harvest period. Reduce water gradually. November-December: Move to warm location or let die off. Save seed. January-February: Treat as annual or save seed.

Winter hardiness

Physalis pubescens is frost-sensitive although not as much as Physalis angulata. At temperatures below 0 degrees Celsius the plant dies off. In cooler climates it is thus an annual plant.

In very mild regions you can sometimes overwinter the plant with protection. Place it in shelter and give minimal water.

You can save seed for next season.

Pests and diseases

The plant can be affected by whitefly and spider mites, especially in warm weather. Regular spraying helps preventively. With infestation use ecological control.

Diseases are usually caused by too much moisture or poor air circulation. Ensure good ventilation and water at the base of the plant, not on the leaves.

Rust can occur in moist periods - ensure good drainage.

Companion plants

Physalis pubescens combines well with other vegetables and herbs such as tomatoes, peppers, and basil. It can also look nice among ornamental flowers in mixed gardens.

In containers it combines nicely with hanging plants such as Solanum jasminoides or climbing tomatoes.

Food and use

The fruits of Physalis pubescens are very edible and have a fine, sweet taste. They can be eaten fresh, in salads, with yogurt, or processed into jam, compote, liqueur, or tropical desserts.

The fruits contain much vitamin C, phosphorus, and potassium. They can be stored up to 1 month in the refrigerator.
