Re: List of 7b palms?

North Delaware has the double whammy of wet winters and heavy clay.
Due east, just across the river, is southern New Jersey, a coastal plain region of fast draining sandy soils. Marginals like Yucca Rostrata & Yucca Aloifolia seem to do much better there than here, despite temperatures & precipitation being the same.
