Growing notes
- Flowers April–May then goes fully dormant by midsummer — the classic North American spring ephemeral
- Mark the position with a label — the disappearance is total and it is easy to dig into the dormant crowns in summer
- Naturalises well in rich moist woodland soil
- Pair with later-emerging perennials (hostas, ferns) to cover the gap
