Cypella herbertii


Quick Characteristics:

Flower Colors: orange, yellow
Flower Season: mid summer to late summer
 

Cypella herbertii is native to Argentina and Uruguay and is the most widespread and common species of Cypella. Plants grow from 50 cm to 1.2 m tall in grasslands and hills. There are 4 recognized subspecies. This species is one of the most easy to grow and rewarding of South American irids. If well grown, it can flower for several months continuously. Grow the plants in a well-draining mix (about 1:1 organic:inorganic). They do well in a US one gallon pot (~3L). Keep the soil moist during the summer growing season and dryish in winter. Fertilize occasionally during active growth. In the winter, the plant will go dormant if water is withheld. In the San Francisco Bay Area, plants grown outdoors that get winter rain will stop growing but will not go completely dormant. When the weather warms up, new leaves and buds will appear.

This plant is easily grown from seeds. Sow the seeds in the same mix as above in spring, taking care not to overcrowd the pot. Seeds can be sown in a smaller pot and then carefully unpotting the plants without disrupting the soil and placed into a one gallon pot. Conversely, seeds can be sown directly into a one gallon pot. The most vigorous seedlings will flower in the first year. Photo 1 was taken by Alessandro Marinello. Photos 2-3 were taken by Nhu Nguyen.

Cypella herbertii ssp. brevicristata is the more common subspecies with yellow or orange flowers. The stigma lobes are short. The first photo was taken by Germán Roitman and the second by Lee Poulsen who thinks that the plants belong to this subspecies.
