<i>Origanum </i>plant named ‘Gilt Trip’

Abstract

The new and distinct hardy perennial plant, Origanum ‘Gilt Trip’, has dense, rounded, habit with heavily-branched spreading stems. The foliage is ovate, and chartreuse to light-yellow and resists burning when planted in full sun. Flowering begins in early summer and continues to early fall or frost with light lavender petal colors with persistent mauve calyces. The new plant is attractive and useful in the landscape en masse, as an accent, or in containers.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The photographs of the new plant Origanum ‘Gilt Trip’ are in a full sun trial garden in Zeeland, Michigan and demonstrate the unique aspects of the new plant. The colors are as accurate as reasonably possible with color reproductions. Ambient light spectrum, temperature, source, and direction may cause the appearance of minor variations in color.

(2) FIG. 1 shows the overall habit of a two-year-old plant in mid-season flowering.

(3) FIG. 2 shows a close-up of the foliage on a one-year-old plant prior to flowering.

DETAILED PLANT DESCRIPTION

(4) The following descriptions are based on a two-year-old plant of Origanum ‘Gilt Trip’ grown in a full-sun display garden in sandy loam with supplemental water and fertilizer as needed.

The new plant has not been observed under all possible environments. The phenotype may vary slightly with different environmental conditions, such as temperature, light, fertility, moisture, and maturity levels, but without any change in the genotype.
