A small, cherry-tomato fruit ripening to an orange-yellow, enclosed in a calyx. Flavor is sweet, tasty and much like some of its better known Physalis relatives.
Seeds are not available for the Cotztomatl. Please visit our seed store to view current selections. Seeds were last available in August 2011.
A low-growing annual to 1-2ft. Little seems to be known or written about this plant, but growth habit is similar to other Physalis species though plant morphology is a bit different.
Unknown, probably not frost hardy but can be grown anywhere as an annual.
Provide regular water. Does not need but thrives in high humidity environments. Excellent candidate for container growth.
By seeds, which usually germinate within a few weeks. Fruits can develop and ripen from seed in just a few months.
Physalis seeds are usually fairly easy to germinate, though germination time can be a bit longer than other vegetable seeds.
1) Prepare for planting. Physalis seeds should be sprouted in small containers, preferably 4" or smaller. In-ground germination is not recommended because conditions are not as easily controlled. Use a standard potting mix that is well drained. Make sure potting mix is damp prior to planting the seeds. With very small seeds such as Physalis, watering overly dry soil can cause the seeds to dislodge from their position and sink deep into cracks in the soil. Seeds that sink deeply into soil will not be able to reach the soil surface once germinated.
2) Plant seeds. Plant seeds 1/4" deep in the soil. Cover with soil and water carefully. Over watering can cause fungal growth which leads to seed rot. Excess water can also bury seeds deep in the soil where they will not be able break the surface. Water when the soil surface just begins to dry. Multiple seeds can be planted in a single starter container, but should be thinned once seedlings appear so only a single plant remains.
3) Germination. Soil should be kept consistently warm, from 70-85F. Cool soils, below about 60-65F, even just at night, will significantly delay or inhibit germination. Hot soils above 95F will also inhibit germination.
4) Care of seedlings. Once a few true leaves have developed, seedlings should be slowly moved outside (if sprouted indoors) to ambient light. Care should be taken not to expose seedlings to direct, scorching sun so plants may need to be hardened off via slow sun exposure. Hardening off can be done using a shaded or filtered light location, as well as protection from strong winds, rain or low humidity. Hardening off time varies, but can take 5-10 days.
5) Planting out. Plant in the ground once danger of frost has past and daytime temperatures consistently reach 65F.
Germination time: 2-6 weeks under ideal conditions.
Fruits can be eaten fresh. This species is little known and extremely rare in cultivation.
Native to South America.
