I was transplanting some Allium canadense bulbs today and disturbed this large spring beauty (Claytonia virginica) tuber only just below the surface! I’ve tried growing this species from different sources and in different parts of the garden, but it’s only in this shady place has it grown well, sourced from a woman in Marathon, Wisconsin in 2004! It has been spreading slowly in recent years and is totally hardy! So this tuber could have taken 14 years growing to this size! Must have a taste this autumn!
