Botanical illustration of Foamflower
Perennial · Tiarella cordifolia

A lovely, well-mannered native groundcover for moist shade — patterned maple-like leaves (many with burgundy markings) and delicate spring spikes of foamy white flowers alive with small bees. It knits into a gentle weed-proof carpet, semi-evergreen in mild winters, and layers beautifully with ferns, bluebells, and coral bells. Deer-resistant and one of the easiest shade natives.

PruningRemove tired leaves in spring — A charming native groundcover for moist shade — mounds of maple-shaped, often burgundy-veined leaves (semi-evergreen) topped in spring by airy spikes of foamy white flowers that feed small bees. It spreads politely by runners into a weed-smothering carpet and pairs beautifully with ferns, heuchera, and bluebells. One of the best-behaved native shade groundcovers. Deer-resistant.

Questions

Foamflower questions, answered straight.

Do deer eat foamflower?

Rarely — foamflower is considered deer-resistant, which makes it one of the safer unfenced choices in deer country. Hungry deer in a hard winter test every rule, but it's a low-risk pick.

Is foamflower safe for kids and pets?

Foamflower is commonly eaten and isn't considered toxic, but "commonly eaten" isn't a guarantee for any particular person or animal — allergies, quantity, and which part you eat all matter. Never eat a plant you haven't positively identified, and check with a vet before letting pets or livestock graze anything new.

How do you propagate foamflower?

Division or seed.
