R.I. Gen. Laws § 2-18.1-8: What nursery stock may be offered for sale.

Only certified nursery stock, stored or displayed under conditions which will maintain its vigor shall be offered for sale. Offering for sale of dead nursery stock or of stock so seriously weakened by drying, excessive heat or cold or any other condition that makes it unable to grow satisfactorily when given reasonable care is deemed a violation of the provisions of this chapter.
