As long as you add plenty of compost or peat moss as well as Bio-tone starter food to the planting holes…everything will grow fine in the sand. There are too many options for sun to list here…lilac, spirea, weigela, junipers etc., etc. The best idea is to come to the garden center with a drawing of the area so we can have an idea of the space and then we can make some suggestions and you can decide what you like.
