Ulluco is part of the Ullucus genus and its scientific name is Ullucus tuberosus. The tuberosus part of this plant's botanical name means 'tuberous'.

Ulluco is another tuber forming plant that is perennial, but grown as an annual. Even in a frost free climate, the top growth will senesce and the plant will grow again from tubers the following year. In cultivation, it is necessary to dig up the tubers and replant at a wider spacing in order to maintain good yields.

Mature bloom diameter is on average approximately 0.3 cm (0.12 inches). The blooms display an average of 5 petals.

Ulluco grows as an annual and is a flowering edible vegetable. Being an annual plant, it tends to grow best over the course of a single year.

Normally reaches to a mature height of 1.30 feet (or 40.0 cm). This plant tends to bloom in mid summer, followed by first harvests in early winter.

Peru is believed to be where Ulluco originates from.

Be aware that Ulluco typically needs a fair amount of maintenance and care in order to grow successfully. Ensure that you are aware of the soil, sun, ph and water requirements for this plant and keep an eye out for pests.

Growing Ulluco from seed

Ulluco does not commonly set seed. Germination and transplanting conditions are not well known.

Ulluco is almost always grown from tubers.

Transplanting Ulluco

Tubers benefit from starting early (March in the northern hemisphere) and transplanting out once risk of frost has passed. They can also be planted directly, at a depth of about 5cm, but can take a long time to sprout in cool soil.

Ensure that temperatures are mild (minimum night temperatures should be around 10°C / 50°F) and all chance of frost has passed before planting out, as Ulluco is a tender plant.

Harvesting Ulluco

Doesn’t begin to form tubers until after the fall equinox and may require as much as five months for tubers to reach maximum size (February in the northern hemisphere). In most of North America and Europe, plants will be killed by frost before maximum yield is achieved. Extending the season by planting in containers or using frost shields can help to produce a better harvest. Two months of growth following the fall equinox should be considered the minimum to produce a reasonable food crop.

Seed Saving Ulluco

Conditions for seed production are not well known. It appears that a mild, moist climate may be a requirement. Seeds were produced in 2013 during a period where the daytime high temperature did not exceed 21 degrees C and humidity averaged 85%. The varieties Pica de Pulga and BK10425.2 have been observed to produce seed.
