The half hardy perennial Anoda typically flowers from the middle of summer until the first frost of autumn.
Some of the common and latin names for the plant include Spurred anoda, Anoda cristata, and Dioda anoda.
Anoda are upright plants that typically grow to between 30 centimetres and 75 centimetres (12 to 30 inches) in height. They have cup shaped solitary flowers of yellow, blue, purple or white, and lobed leaves. They make great border plants.

It is best to plant Anoda just below the soil surface at a depth of about half a centimetre, with a spacing of approximately 30 centimetres (one foot).
Anoda should be planted out just after the last frost of spring. Anoda prefers to be grown in the sun, but may require light shade in the afternoons in particularly hot areas. The soil type is not important, but should be well drained. When starting Anoda off from seed indoors, the seeds should planted two to three weeks before they are due to be planted outside, ideally after the last frost.
Anoda care is quite simple. They require to be watered during very dry spells. The plant should be deadheaded following flowering to prevent them from taking over the garden. Anoda should be mulched in the autumn in very cold areas.
