Vigorous, fast-growing, medium-sized, native deciduous tree which occurs on floodplains, swampy bottomlands, and along streams. Can be trained as a single or multi-trunked tree. Salmon-pink to reddish-brown exfoliating bark and yellow fall color. River birch is perhaps the most culturally adaptable and heat tolerant of the birches.
‘Cully’ features salmon-cream to brownish bark which exfoliates to reveal a creamy white inner bark that can be nearly as white as the white-barked birches. It is commonly sold as Heritage river birch. According to Missouri Botanical Gardens, it was found growing in St. Louis, Missouri by Earl Cully and was issued a patent in 1979.
