[Overview]
An annual or perennial.
The stems and leaves are covered with many soft, somewhat sticky glandular hairs.
The leaves are simple and alternate, elliptic to lanceolate, with finely and shallowly serrated margins or entire margins.
A single yellow to deep orange flower head is borne at the tip of the flower stalk.
The fruit is an achene without a pappus, strongly curved like the letter C.
[Cultivation]
Propagate from seed.
It is easy to grow.
It prefers a sunny, well-drained, moisture-retentive site.
Without enough sun, it flowers poorly.
It grows poorly in acidic soil and prefers slightly alkaline soil.
It is cold-hardy, but frost and snow damage the leaves, so frost protection may be provided.
Water thoroughly when the soil surface dries.
If base fertilizer is applied, little further fertilizer is needed.
Seed formation tires the plant, so remove flowers promptly after they bloom.
Pests and diseases include powdery mildew, cutworms and aphids.
