I've only seen this plant upon visiting Jenkins Arboretum close to Berwyn, Pennsylvania, west of Philadelphia. I took photos of it from there. It is native to the Appalachian Mts of WV, VA, TN, & NC. Mountain Pieris differs from the extremely common Japanese species planted so much in southeast PA in that the flower clusters are erect. The foliage tends to be a little less glossy too. I don't think this species gets over six feet high, while the Japanese can. 'Brouwer's Beauty' is a hybrid with this and the Japanese species that has flower clusters that are in between erect and drooping. The American species is hard to propagate. There is an article in Hort Science 36(2) 353-356 in 2001 about micropropagated in vitro culture with ercoid micorrhizae from NC University. Weston Nursery at 93... read more

Shrub has endured despite a less than stellar site placement (west-facing side of house exposed to sweeping winter winds).

Pieris floribunda is indeed a North American native. According the the University of Connecticut website: "native to primarily North and South Carolina, but also found in Virginia and Georgia."

Also from UConn: "upright clusters of small, white urn-shaped flowers, about 2" to 4" long."

I live in Southern PA and would like to try growing it here but have not been able to find any local sources for it. Everyone has the Japanese species.

for what its worth, the pictures of the pieris attached to this plant file (Pieris floribunda) are actually Pieris japonica. Floribunda's flowers are upright. Japonica's flowers are drooping.

Japonica is the more commonly found plant. I believe floribunda is native.

i have a pieris mountain fire and i just planted it this year, but what i need to know is how can you propagate it.
i have it in partial shade in zone 8. of course it is still to early to tell whether or not the plant will make it through next year, right now it is fine. can someone please tell me how to propagate it?

Elegant in foliage and form all year, these plants make good companions to rhododendrom and azalias. Whorls of leathery, narrowly oval leaves: clusters of small, typically white, urn-shaped flowers. Compact, and rounded- typically 3-6 feet tall. New growth is pale green; mature leaves are dull dark green. Blossoms in upright clusters. Very cold hardy. Tolerates sun and low humidity. Most will form flower buds by autumn, so potential flower clusters are possible over winter. Need well-drained but moisture-retentive acidic soil.
