Purple toothwort
Lathraea clandestina
Purple toothwort is a fascinating holoparasitic plant that produces stunning violet flowers in early spring but has no green leaves and cannot photosynthesize — it must be planted near a compatible host tree such as willow, alder, or hazel to survive. Establishing it requires patience and the right host root contact, making it a rewarding challenge for specialist gardeners. Keep the planting area consistently moist and shaded, and avoid disturbing the root zone once planted.
