plant named ‘Mai Tai’

Abstract

A new, distinct Geum plant as shown and described, characterized by single and semi double flowers that open vermilion then fade to peach and then finally fade to pink.

Description

Latin name: Geum hybrid.

Cultivar name: ‘Mai Tai’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct hybrid of Geum plant named ‘Mai Tai’ characterized by single to semi double flowers that open vermilion then fade to peach and then finally fade to pink. The new Geum was raised as a seedling from a controlled cross of Geum Mango Lassi, not patented, and Geum ‘Flames of Passion’ U.S. Pat. No. 13,730, patented, in Hebron, Ill. in 2005. The selection of the new plant was due to its' unique and multi colored single and semi double flowers that open vermilion then fade to peach and then finally fade to pink. Asexual division have been the means of reproduction. The intial division propagation has taken place at a nursery Hebron, Ill. since 2006. The new Geum has shown to be stable and identical in reproduction to the parent after dividing over 70 two year old plants resulting in over 700 divisions from 2006 to 2009.

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 ‘Mai Tai’ characterized by single and semi double flowers of RHS 53B fading to 48C and finally to 36B and 36C compared to the parents have been observed to be unique and stable.

Plants of the new Geum can be compared to plants of female or seed parent Geum ‘Flames of Passion’ U.S. Pat. No. 13,730, patented. 1. The new plant flower colors are 53B which fades to 36B and 36C and finally to 48C while Geum ‘Flames of Passion’ has a red flower color 179 A.

Plants of the new Geum can also be compared to the female or seed parent plant Geum ‘Mango Lassi’, not patented. 1. The new plant flower colors are 53B which fades to 36B and 36C and finally to 48C while Geum ‘Mango Lassi’ has a golden yellow 14 B and orange red 44 A flower color.
