Plant description
The species has gray-green, deeply incised leaves that are hairy like the stems.
The gray-green color suggests that this species likes to be sunny, dry and well-drained.
In very warm places, he will thank you for some afternoon shade. Mainly used because of the attractive fluffy seeds.
The soil must never dry out! Please note: in winter the soil should not be too wet, as this causes root rot.
