<i>Dracaena </i>plant named ‘DRA201901’

Abstract

A new and distinct Dracaena plant named ‘DRA201901’ which is characterized by an abundance of foliage born on an unbranched stem, glossy green foliage with broad yellow-green margins, foliage that is slightly to moderately spiraled and distally curled downward, coarsely undulate foliar margins, and the stability of these characteristics from generation to generation.

Claims

1. A new and distinct cultivar of Dracaena plant named ‘DRA201901’, substantially as described and illustrated herein.

Description

BRIEF DESCRIPTION OF THE FIGURES

(1) FIG. 1 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, an exemplary plant of ‘DRA201901’ grown in Honselersdijk, the Netherlands. This plant, grown in a 11 cm nursery container, is approximately 16 weeks old from a rooted young plant; and

(2) FIG. 2 illustrates, as nearly true as it is reasonably possible to make the same in color photographs of this type, the typical foliage of ‘DRA201901’.

BOTANICAL DESCRIPTION OF THE PLANT

(3) The following observations and measurements, made in May of 2020, describe averages from a sample set of six specimens of 12 week-old ‘DRA201901’ plants grown in 15 cm nursery pots in Honselersdijk, the Netherlands. Plants were produced using conventional greenhouse production protocols for Dracaena sp. which consisted of growing under shade, regular overhead irrigation and regular fertigation, and chemical control of thrips insects. No photoperiodic treatments or artificial light was given to the plants.

(4) Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘DRA201901’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 (sixth edition).

Root system: General.—Fibrous; freely branched and moderately dense rooting. Distribution in the soil profile.—Shallow to moderately deep. Texture.—Smooth; glabrous. Color.—Greyed-orange, RHS N170A. Stems: Branching characteristics.—Not freely branched in nature; develops lateral branches only when manipulated by man by way of pruning. Naturally produces one main stem arising from the plant's base. Attitude.—Near vertical. Strength.—Very strong. Length.—36.0 cm. Diameter.—Average 1.5 cm. Internode length.—Average 1.3 cm.

Color, mature stems.—Yellow green, nearest to a mixture of RHS 145B and in between RHS 146A and 147A. Color at the internodes.—Yellow green, nearest to in between RHS 146A and 147A. Foliage: Arrangement.—Spiraled. Attachment.—Sheathed. Division.—Simple. Attitude.—Foliage near the apex is held upright to outward and becomes progressively more relaxed towards the base. Number of leaves per lateral branch.—42. Lamina.—Dimensions — 21.6 cm long and 6.4 cm wide, on average. Shape — Lorate. Aspect — Slightly to moderately axially twisted (i.e. spiraled); distal portion on the lamina pointing downward at an average angle of minus-60 degrees to the rest of the lamina. Apex — Acute with a short, soft but pointed tip. Base — Sheathed. Sheath Length — 2.4 cm. Width — 4.5 cm. Color, adaxial surface — Green-white, nearest to RHS 157A. Color, abaxial surface — Yellow-green, nearest to RHS 147A, and suffused with green, nearest to RHS 139A. Margin — Entire; coarsely undulate. Texture and luster of adaxial surface — Smooth, glabrous and moderately glossy. Texture and luster of abaxial surface — Smooth, glabrous and moderately glossy. Color — Juvenile foliage, adaxial surface — In between yellow-green and green, nearest to RHS 143A and 146A, but darker; broadly margined yellow-green, nearest to in between RHS N144A and 150A. Juvenile foliage, abaxial surface — Green, nearest to RHS 143A, and margined yellow-green, nearest to RHS N144A. Mature foliage, adaxial surface — Green, nearest to in between RHS NN137A and 139A, but slightly darker; irregularly margined yellow-green, nearest to RHS 144B. Mature foliage, abaxial surface — Green, nearest to RHS 143A, but darker; irregularly margined yellow-green, nearest to RHS 144B. Venation — Pattern — Parallel. Color, adaxial surface — The main vein nearest green, nearest to RHS 137A. All other veins are indistinguishable from the surrounding foliage: green, nearest to in between RHS NN137A and 139A, and irregularly margined yellow-green, nearest to RHS 144B. Color, abaxial surface — The main vein is green, nearest to RHS 143B. All other veins are indistinguishable from the surrounding foliage: green, nearest to RHS 143A, and irregularly margined yellow-green, nearest to RHS 144B.
