Ground Cherries
Physalis pruinosaA small, sweet relative of the tomatillo, grown for its golden, pineapple-scented fruit tucked inside a papery husk. Unlike most garden fruit, ripe berries simply drop to the ground, so a light mulch or ground cloth makes harvest easy. The one rule: wait for husks to turn tan and papery — fruit picked green never sweetens.

When to sow ground cherries
- Sow from about 2 weeks after your last expected frost until about 14 weeks before the first expected autumn frost.
Start indoors — sow 6–8 weeks before the last frost date.Keep compost around 24°C for even, reliable germination.Transplant two to four weeks after the last frost, once nights are mild.
Let plants sprawl — dense, spreading foliage smothers weeds nearby.Mulch underneath to keep fallen fruit clean and easy to spot.Water deeply during dry spells to keep fruit sizing up well.
Wait for husks to turn tan and papery — this signals a ripe, sweet fruit.Gather fruit that has dropped to the ground; ripe berries fall freely.Store unhusked fruit at room temperature for several weeks after picking.
Companion plants
Dense ground cherry foliage suppresses weeds around taller neighbors like kale, though other nightshades nearby compete for the same soil resources and pests.
Watch out for
Flea beetles — Perforate young leaves with small holes in warm, dry weather. Cover transplants with fine mesh until well established.Ground cherry leaf beetle — Skeletonizes foliage through summer. Hand-pick beetles and larvae, or cover plants with insect mesh.
