Mountain Laurel grows wild but can be found for sale in nurseries.
I copied and pasted the following:
This shade-tolerant North American shrub has gorgeous flowers that bloom in late spring and early summer. A close relative of rhododendrons and azaleas, it’s an excellent choice for a shady garden. It’s also evergreen, so even after the blooms have faded, its leathery deep green foliage provides a welcome sign of life. Even in the coldest winter weather, when rhododendron leaves have curled in on themselves, mountain laurel remains bravely open to the elements.
Mountain laurel was first recorded growing in the wild in 1624 and can be found on rocky ridges and mountainous forest areas as far south as the Florida Panhandle, as far north as southern Quebec, and as far west as Indiana and Louisiana. In spring it can be seen blooming abundantly along the Blue Ridge Parkway in North Carolina and, closer to New York City, in the forests of upstate New York, notably near Lake Minnewaska, in Ulster County. It is the state flower of both Connecticut and Pennsylvania.
All parts of Kalmia latifolia are poisonous if ingested and can cause severe digestive upset and other alarming, though usually nonfatal, symptoms such as weakness and paralysis. Not all animals are affected—deer, unfortunately, are apparently immune to any ill effects and can be vigorous consumers of mountain laurel foliage.
