Ecological Value

Shrubby St Johns Wort is a pollinator powerhouse Its bright yellow flowers with prominent golden stamens bloom mid to late summer providing valuable nectar and pollen when many early species have finished

It supports native bees butterflies and beneficial insects and adds mid season structure to prairie and savanna plantings

This is a compact fine textured native shrub with upright branching and narrow blue green foliage In summer it becomes covered in cheerful star shaped yellow flowers that stand out in dry landscapes and restoration sites

It thrives in well drained soils and tolerates drought once established making it ideal for prairie plantings dry slopes urban restoration sites and climate resilient landscapes

Ecological and Climate Adaptation

Shrubby St Johns Wort is well suited to hotter drier summer conditions increasingly common in southern Ontario Its tolerance for lean soils and drought makes it a strong candidate for long term low input plantings

Deep woody roots help stabilize soils while its compact form makes it useful in layered shrub and meadow systems
