USPP34617P2 - Heuchuera plant named ‘ALCHEFRIL’ - Google Patents

Abstract

A new cultivar of Heuchera plant named ‘ALCHEFRIL’ that is characterized by its foliage with heavily ruffled leaf margins, its very robust, compact plant habit, its leaves that are compounded with deeply lobed leaflets, its globe shaped plant habit, its moderate growth rate, and its flowering stems that are moderate in length.

Description

Botanical classification: Heuchera hybrid.

Cultivar designation: ‘ALCHEFRIL’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Heuchera of hybrid origin, botanically known as Heuchera ‘ALCHEFRIL’ and is hereinafter referred to by its cultivar name ‘ALCHEFRIL’.

The Inventor discovered the new cultivar May of 2016 as a naturally occurring branch mutation of Heuchera ‘Tangerine Wave’ (not patented) in a container block at his nursery in Waunfawr, Gwynedd, United Kingdom.

Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor by basal cuttings in 2017 in Waunfawr, Gwynedd, United Kingdom. Asexual propagation of the new cultivar by basal cuttings and tissue culture using meristematic tissue has determined that the characteristics of the new cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘ALCHEFRIL’ as a new and unique cultivar of Heuchera.

• • 1. ‘ALCHEFRIL’ exhibits foliage with heavily ruffled leaf margins.
  • 2. ‘ALCHEFRIL’ exhibits a very robust, compact plant habit.
  • 3. ‘ALCHEFRIL’ exhibits leaves that are compounded with deeply lobed leaflets.
  • 4. ‘ALCHEFRIL’ exhibits a globe shaped plant habit.
  • 5. ‘ALCHEFRIL’ exhibits a moderate growth rate.
  • 6. ‘ALCHEFRIL’ exhibits flowering stems that are moderate in length.

The seed parent of ‘ALCHEFRIL’ differs from ‘ALCHEFRIL’ in having a larger plant size, flat, non-ruffled foliage, an open, lax and less robust plant habit. ‘ALCHEFRIL’ can be most closely compared to the Heuchera cultivars ‘Caramel’ (U.S. Plant Pat. No. 16,560) and ‘Marmalade’ (U.S. Plant Pat. No. 15,945). Both ‘Caramel’ and ‘Marmalade’ are similar to ‘ALCHEFRIL’ in foliage coloration. ‘Caramel’ differs from ‘ALCHEFRIL’ in having leaves that are larger in size, a more open plant habit, and less leaves per plant. ‘Marmalade’ differs from ‘ALCHEFRIL’ in having smoother foliage, a more open plant habit and less leaf pubescence.
