The illustrated growing guide
Foamflower
Tiarella cordifolia
Family Saxifragaceae
Est. zones 3-8

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.

What foamflower is grown for

Edibility, identification, and traditional-use notes here are general reference — not medical or veterinary advice, and not a claim that any plant treats or prevents anything.

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.
