USPP31455P2 - Leucanthemum plant named ‘Lemon Puff’ - Google Patents

Abstract

A new and distinct Leucanthemum plant named ‘Lemon Puff’ characterized by double daisy type inflorescences, yellow inflorescence buds and young ray florets, fully open inflorescences that are medium sized and display numerous white and yellow ray florets around a gold disc, ray florets that are obelliptic to linear with mildly lacerated tips giving a more fluffy appearance to the inflorescence, excellent bloom number, a low, compact habit, and excellent vigor.

Description

Botanical denomination: Leucanthemum x superbum.

Variety designation: ‘Lemon Puff’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Leucanthemum given the cultivar name ‘Lemon Puff’. Leucanthemum is in the family Asteraceae. The exact parents for this cross are unknown; the new cultivar originated from a controlled cross between unnamed, proprietary Leucanthemum x superbum seedlings.

Compared to Leucanthemum ‘Bridal Bouquet’, U.S. Plant Pat. No. 24,260, the new cultivar is more double, and has shorter ray florets and a taller habit.

Compared to Leucanthemum ‘Macaroon’, U.S. Plant Pat. No. 26,905, the new cultivar is taller and has smaller flowers.

Compared to Leucanthemum ‘Victorian Secret’, U.S. Plant Pat. No. 22,654, the new cultivar has smaller flowers.

SUMMARY OF THE INVENTION

This new Leucanthemum cultivar is uniquely distinguished by:

• • 1. double daisy type inflorescences,
  • 2. yellow inflorescence buds and young ray florets,
  • 3. fully open inflorescences that are medium sized and display numerous white and yellow ray florets around a gold disc,
  • 4. ray florets that are obelliptic to linear with mildly lacerated tips giving a more fluffy appearance to the inflorescence,
  • 5. excellent bloom number,
  • 6. a low, compact habit, and
  • 7. excellent vigor.

This new cultivar has been reproduced only by asexual propagation (division and tissue culture). Each of the progeny exhibits identical characteristics to the original plant. Asexual propagation by division and tissue culture using standard micropropagation techniques with terminal and lateral shoots, as done in Canby, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with variations in environment without a change in the genotype of the plant.
