Pursuant to the provisions and requirements of the Colorado Nursery Act to regulate the sale and distribution of nursery stock, and by authority of Title 35, Article 26, Section 111, CRS 1973, the following rules and regulations are hereby promulgated:
26-1.0 DEFINITIONS 26-1.1 “Balled and burlapped stock” means that nursery stock which has been removed from the growing site with a ball of soil, containing the root system, left intact and encased in burlap or other similar material to hold the soil in place, and shall also include that nursery stock which has been removed from the growing site by a mechanical spade or other machine with a ball of soil, containing the root system, left intact but not necessarily encased in burlap or other similar material.
26-1.2 “Balled and potted stock” means that nursery stock which has been removed from the growing site with a ball of soil, containing the root system, left intact and placed in a container. 26-1.3 “Bare root stock” means that nursery stock which has been removed from the growing site with the root system substantially free of soil.
26-1.4 “Container grown stock” means that nursery stock which has been planted in a container with the root system in soil, or other potting mixture capable of sustaining normal plant growth, and which has become established in the container and exhibits a well-rooted condition as evidenced by the soil ball remaining intact when removed from said container. 26-1.5 “Etiolated growth” means bleached and unnatural growth resulting from the exclusion of sunlight. 26-1.6 “Packaged stock” means that bare root nursery stock packed with the roots in peat, shingletow, or other moisture-retaining material encased in plastic film or other material designed to hold the moisture-retaining material in place.
26-1.7 “Plantable container” means a container which, when planted in the soil, will allow root penetration within one growing season.
26-1.8 “Potted stock” means that nursery stock which has been planted in a container with the roots in soil or other potting mixture capable of sustaining normal plant growth, which has not become established as described in 26-1.4 of these definitions. 26-1.9 “Primary bud” means the most vigorous bud at a node. 26-1.10 “Prohibited weeds in turfgrass sod” means the following plant species except when any of these species is labeled for sale purposes in accordance with Section 35-26-104 (3), CRS 1973, as amended, and 26-4.2 of these rules and regulations:
26-1.11 “Weeds” means any plant species other than the species labeled in accordance with Section 35- 26-104 (1), CRS 1973, and 26-4.2 of these rules and regulations. 26-1.12 “Bench packed stock” means that nursery stock with the roots packed in a growing medium mixture to form a ball, and encased in burlap or other similar material to hold the growing medium in place.

This sales name shall identify the grower and may or may not disclose the varieties or kinds or percentages of each in the blend or mixture. 26-1.16 “Sell or offer for sale” and “sale” mean, for the purposes of the Colorado Nursery Act and these rules and regulations, all times in which the person engaged in the business of selling nursery stock has custody or control of the nursery stock, including those acts leading to the transfer, or the transfer of the nursery stock for consideration either in money or its equivalent. For the purposes of the Colorado Nursery Act and these rules and regulations, the transfer shall not be deemed to have occurred until such time that the person engaged in the business of selling nursery stock ceases to have custody or control of the nursery stock. 26-1.17 “In-ground fabric bag-grown stock” means that nursery stock which has been planted in a fabric bag with the root system in soil, or other potting mixture capable of sustaining normal plant growth; which, in turn, has been field planted while in the bag; and which has become established in the bag and exhibits a well-rooted condition, as evidenced by the soil ball remaining intact when removed from the bag.

Collected. (Coll.) Natural seedling plants dug from native stands or forest plantings must be so designated.
EVERGREENS - CONIFERS Type 1 - Spreading Measurement designates spread (height not considered). Use 3 inch intervals up to 18 inches. Use 6 inch intervals from 18 inches up to 4 feet. Use 1 foot intervals from 4 feet up. Measurement shall be average of plant and not the greatest diameter. Plants properly trimmed and transplanted should measure the same in any direction. If a plant is uneven, for example, 15 inches the widest way and 9 the narrowest, it should be classified as 12 inch stock. Examples:

GENERAL Measurement of height shall begin where the branches start rather than at the ground, if the plant is leggy. It shall stop where the main part of the plant ends and not at the tip of a thin shoot. 26-2.4 ROSE GRADES GENERAL The standards specified apply only to field-grown two year roses when sold either bare root, or individually wrapped and packaged, or in cartons.
All grades of roses must have a well-developed root system and have proportionate weight and caliper according to grade and variety. Roses shall be graded by number and caliper of canes by size, number and length of canes, and proper consideration should be given to weight and caliper of canes, depending upon grade and variety.
As used in the grade sizes below, “strong cane” means a cane that is healthy, vigorous, and fully developed so that it is hardened-off throughout. The caliper of the cane is measured not higher than 4 inches (10 cm) from the bud union. Finished shipping length shall be not less than 6 inches (15.0 cm).

Grade No. 1 ½ - 2 or more strong canes to be 15 inches and up, with the exception of a few of the light growing sorts which are to have 2 strong canes 13 inches and up, branched not higher than 3 inches above the bud union.
Grade No. 2 - 2 or more strong canes 12 inches and up, with the exception of a few of the light growing sorts which are to have 2 or more canes 10 inches and up, branched not higher than 3 inches above the bud union.
Although Floribunda roses are included in the above grade standard, it should be noted that Floribunda roses in this group will normally result in the marketing of rose bushes which are, on the average, lighter for this class. Polyantha, Shrub, Landscape, and low growing Floribunda roses may be graded per Subpart B, immediately below.
