How to Identify
Physalis subglabrata is a perennial plant reaching 1.5 m (5 ft) in height. Hardy to UK zone 5 and not frost tender. Foliage appears from May to October, with flowers blooming August to September. The plant is hermaphroditic and insect-pollinated. It thrives in light sandy, medium loamy, and heavy clay soils with good drainage, tolerating mildly acidic, neutral, and mildly alkaline pH levels. Growth occurs in semi-shade or full sun, with adaptability to both dry and moist conditions.
How to Grow
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors at least in the milder parts of this country. If it proves to be tender, it should be possible to treat it as an annual, sowing the seed in early spring in a warm greenhouse and planting out after the last expected frosts. There is some confusion over the name of this species, it might be best treated as a sub-species of P. virginiana, when it will be P. virginiana subglabrata. (Mac. Kenzie.&Bush.)Waterfall. The plant has a deep rootstock. The following notes are based on the general needs of the genus. Succeeds in any well-drained soil in full sun or light shade.
Propagation: Sow seed in March or April in a greenhouse, barely covering it. Germination is typically quick and prolific. Diurnal temperature fluctuations assist germination. Once large enough to handle, prick seedlings out into individual pots of fairly rich soil and plant out after the last expected frosts, with cloche protection until established. Division in spring is very straightforward — larger divisions can go directly into permanent positions, while smaller ones are better potted up and grown on in light shade in a cold frame until well established before planting out in late spring or early summer. For basal cuttings in early summer, harvest shoots with plenty of underground stem when they reach about 8–10cm above ground, pot into individual pots, and keep in light shade in a cold frame or greenhouse until rooting well before planting out in summer.
