Cultivation methods
Androcymbium scabromarginatum Schltr. & K.Krause, also known as Rough Margin Androcymbium, is a plant that belongs to the family Colchicaceae. This plant prefers to grow in well-drained soil that contains organic matter. The ideal location for planting the Rough Margin Androcymbium is an area that receives partial to full sunlight, but it can tolerate some shade as well. It is best to plant the Rough Margin Androcymbium in the spring.
Watering needs
The Rough Margin Androcymbium prefers to grow in soil that is consistently moist but not waterlogged.
