The Story
Plant Bio
Caltha palustris is a clump-forming, herbaceous perennial that thrives in wet, boggy soils. It features glossy, heart-shaped green leaves and brilliant, buttercup-like yellow flowers in early spring. As one of the earliest native wetland plants to bloom, it provides a vital nectar source for emerging pollinators and brings cheerful color to water margins before other plants have emerged.

Care Guide
Do
- Provide consistent, ample moisture; this plant loves wet feet.
- Allow it to self-seed for naturalized colonies in appropriate areas.
- Remove yellowing leaves after flowering as the plant may go dormant in summer heat.
Don't
- Do not let the soil dry out, even for a short period.
- Avoid planting in deep shade, which reduces flowering.
- Do not ingest any part of the plant, as it is toxic when raw.
