Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
					 General Provisions. Nursery stock, when offered for sale, need not be graded
					 and tagged at the discretion of the person offering the stock for sale; but if
					 it is graded and tagged, it must meet the requirements of this article. Nursery
					 stock when graded by size shall have a well-developed root system and the canes
					 or top-growth shall have proportionate weight and caliper according to
					 grade-size and variety. The number and length of the canes or top-growth
					 specified for each grade-size shall refer to the number and length before such
					 canes or top-growth are cut back or pruned in preparation for sale. Nursery
					 stock which has been cut back or pruned may be compared with other stock of the
					 same class which has not been cut back or pruned, to determine compliance with
					 the grade-size established herein.
(b) Roses. Field-grown bare root rose bushes
					 harvested after the second season of root growth shall be labeled with the
					 grade-size on each bundle when sold at wholesale. Rose bushes which do not meet
					 the lowest grade-sizes shall be labeled as "substandard" whenever sold at
					 wholesale.
The grade-sizes hereby established for each
						classification of rose bushes are minimum sizes and not more than 10 percent of
						the roses in any lot shall be below the size specified.
(1) Tea, Hybrid Tea, Grandiflora, Rugosa
					 Hybrids, Hybrid Perpetuals, and Moss Roses. No. 1 rose bushes shall have three
					 or more strong canes, 16 inches and up, branched not higher than three inches
					 above the bud union.
No. 1 1/2 rose bushes shall have two or more strong
						canes, 15 inches and up, branched not higher than three inches above the bud
						union.
No. 2 rose bushes shall have two or more strong canes, 12
						inches and up, branched not higher than three inches above the bud
						union.
No. 3 rose bushes shall be of good salable and plantable
						quality.

					 Roses. No. 1 rose bushes shall have three or more strong canes, 15 inches and
					 up, branched not higher than three inches above the bud union.
No. 1 1/2 rose bushes shall have two or more strong
						canes, 14 inches and up, branched not higher than three inches above the bud

						11/2 rose
						bushes shall have three or more canes, eight inches and up, branched not higher

						quality.
(4) Climbing Roses.
					 No. 1 rose bushes shall have three or more strong canes, 24 inches and up,
					 branched not higher than three inches above the bud union or crown.
No. 1 1/2 rose bushes shall have two strong canes 18
						inches and up, branched not higher than three inches above the bud union or
						crown.
No. 2 rose bushes shall be of good salable and plantable
						quality.
Effective September 1, 1985, the grade-sizes for roses
						shall be as hereafter specified. At the same time, the foregoing grade-sizes
						for roses shall be void. The grade-sizes for each group of bush rose
						classifications are minimum sizes and not more than ten percent of the roses in
						any bundle shall be below the size specified. As used in the grade-sizes below,
						"strong cane" means a cane that is at least 
						3/16 of an
						inch in caliper regardless of its length, and is healthy, vigorous, and fully
						developed so that it is hardened off throughout the specified length for the
						grade.
(1) Tea, Hybrid Tea,
					 Grandiflora, Rugosa Hybrids, Hybrid Perpetuals, Moss, and Climbing Roses.
No. 1 rose bushes shall have at least three strong canes,
						16 inches (40.6 cm) and up, branched not higher than three inches (7.6 cm) from
						the bud union.
No. 1 1/2 rose bushes shall have at least two strong
						canes, 15 inches (38.1 cm) and up, branched not higher than three inches (7.6
						cm) from the bud union.
No. 2 rose bushes shall have at least two canes one of
						which shall be a strong cane, 12 inches (30.5 cm) and up, branched not higher
						than three inches (7.6 cm) from the bud union.

						which shall be a strong cane, 12 inches (30.5 cm) and up, branched not higher
						than three inches (7.6 cm) from the bud union.
NOTE: Although the grades for floribunda roses are not
						significantly different from those for the hybrid teas, grandifloras, and
						others of that group, as applied they normally should be expected to result in
						the marketing of rose bushes which are, on the average, lighter for this
						class.
