Physalis edulis.
A genuine specialty of the Québec garden, and one of our little botanical treasures unknown outside the province. The ground cherry originally comes from the highlands of Central America, where it has been cultivated by Indigenous peoples since long before the arrival of Europeans. Adopted by the French settlers as early as the 17th century, it adapted so well to the North American continental climate that, over generations, it became almost a local point of pride — it's the ground-cherry pie of grandmothers, the golden jams on the fall stalls of public markets, the small sweet fruits absent-mindedly nibbled standing in the garden.
A low, spreading plant 60 to 90 cm tall, forming a dome of downy grey-green foliage from which hang hundreds of small parchment lanterns of pale beige, each containing a round fruit 1 to 2 cm, golden yellow at maturity, with a unique flavour hard to describe — a meeting between pineapple, mango and tomato, with a lightly caramelized note. The fruits fall to the ground when perfectly ripe (hence the name), and that's exactly when to pick them — a fruit picked off the ground, still in its lantern, is at its sweet optimum. Delicious plain as a natural candy, sublime in a maple-syrup pie, in jam alone or with other small fruits, dipped in melted chocolate as a small holiday treat, laid fresh on a soft cheese, or simply served as dessert as-is alongside a tea.
Grower's tip: Indoor start 6 to 8 weeks before planting out, at 22-25 °C — the ground cherry is a cousin of the tomato (same Solanaceae family) and shares its heat needs. Transplant once all risk of frost is past. Choose the spot with a slight afterthought — the plant self-seeds generously, and it's not uncommon to find dozens of spontaneous seedlings the following year in the same place. Easy harvest: don't pick from the plant — wait for the fruits to fall in their lanterns (they keep ripening on the ground for 1 to 2 weeks, without risk of rot thanks to their parchment envelope). Remarkable storage in their envelope at room temperature — 2 to 3 weeks easily.
- Open-pollinated. Annual. Largely self-fertile, so few crossings to fear.
- Height: 60 to 90 cm, spreading habit.
- Maturity: 65 to 75 days after transplant.
- Exposure: full sun.
- Rich, well-drained, moderately moist soil. Space plants 60 to 90 cm apart — they take up room as they spread.
- Indoor start 6 to 8 weeks before last frost. Transplant once all risk of frost is past and the soil is at 15 °C minimum. Self-seeds generously year after year.
