The Story

Plant Bio

Staphylea trifolia is an upright, suckering, deciduous shrub or small tree native to eastern North America, known for its drooping clusters of bell-shaped white flowers. It produces unique, inflated, bladder-like seed capsules in late summer. The most distinctive feature is its papery, three-lobed, bladder-like seed pods which persist into fall and contain hard, shiny seeds that rattle when shaken.

Bloom Period:

EarlyLate

Uses & Benefits:

Charming, pendulous, bell-shaped white flowers in spring are followed by unique, inflated, papery seed capsules that are interesting in late summer and fall. The compound leaves add a fine texture to the shade garden.

Its tendency to sucker makes it useful for stabilizing soil on moist banks and slopes. It can form a dense thicket, providing a natural screen in woodland settings.

The spring flowers provide an early nectar source for native bees and other pollinators. The thicket-forming habit offers cover for birds and small wildlife.

Planting

How to Grow

Choose a location with partial to full shade and moist soil.
Dig a hole twice the width of the root ball.
Place the plant so the top of the root ball is level with the soil.
Backfill with amended soil, gently firming it around the roots.
Water thoroughly after planting to settle the soil.
Apply a layer of mulch to retain moisture and suppress weeds.

Pro Tip

Control its suckering habit by pruning unwanted shoots at the base to maintain a tidy form in smaller gardens.
