Shrubs for the Island

[Pricestavern]

We’re looking for recommendations on types of shrubbery to plant on Rattlesnake Island. Have a fairly rocky site, brilliant sun in the morning, deep shade in the afternoon. I'm looking for something to help hold what soil there is.

Prefer something that's grows locally, stays low, is hardy and doesn't need much maintenance. Flowering is a plus, but not necessary.

Any suggestions?

Thanks in advance,
R and M
