plant named ‘Gimlet’

Abstract

A new, distinct Geum plant as shown and described, characterized by semi-double to single flowers that open yellow and fade to light yellow with creamy white tips.

Description

Latin name: Geum hybrid.

Cultivar name: ‘Gimlet’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid of Geum plant named ‘Gimlet’ characterized by semi-double to single flowers that open yellow and fade to light yellow with creamy white tips. The new Geum was developed as a seedling as part of an on going breeding and selecting program, in Hebron, Ill. in 2008. The parents of the new plant are unknown. The selection of the new plant was due to its' semi-double to single flowers that open yellow and fade to light yellow with creamy white tips. The initial asexual propagation of the new plant was by division and took place at a nursery in Hebron, Ill. in 2009. Continued asexual propagation by division since that time has shown that the unique features of this new Geum plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart (2001). The new Geum plant named ‘Gimlet’ is characterized by semi-double to single flowers that open yellow RHS 4 A and fade to light yellow RHS 4 C with white tips colored close to RHS 155 C.

The new Geum plant can be compared to ‘Banana Daiquiri’ U.S. Plant Pat. No. 25,351 in that, flower colors are deeper yellow RHS 3 B while the new plant flower color is yellow RHS 4 A and fade to light yellow RHS 4 C with white tips colored close to RHS 155 C.

The new plant can also be compared to Geum ‘Limoncello’ not patented, which has bright yellow single flowers of 9 A while the new plant flower color is yellow RHS 4 A and fade to light yellow RHS 4 C with white tips colored close to RHS 155 C. Plants of Geum ‘Limoncello’ grow shorter to 30 cm tall while the new plant grows 40 cm tall at maturity. Plants of Geum‘Limoncello’ have hairier darker green foliage RHS 147 A while the new plant has foliage color of RHS 137 A.
