Cardamine bulbifera, known as coralroot, is a species of flowering plant in the family Brassicaceae. It is a perennial with upright, mostly unbranched, stems to 70 cm tall, and leaves made up of between three and 13 leaflets.
This can be given perhaps every 3 or 4 weeks or so when watering during the growing season. The aim is just to keep the plants healthy and active in their limited volume of soil, not to encourage lush, rapid growth - hence the use of fertilisers at low rate only.
Suitable pH: acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It prefers dry or moist soil.
