plant named ‘Bococot’

Abstract

A new cultivar of Sorbaria sorbifolia plant named ‘Bococot’ that is characterized by its compact, dense and consistent plant habit, its floriferous blooming habit in summer, its foliage that is deep pink-red in color, and its fruits that are greyed-red in color.

Description

Botanical classification: Sorbaria sorbifolia.

Variety denomination: ‘Bococot’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sorbaria sorbifolia and will be referred to hereafter by its cultivar name, ‘Bococot’. ‘Bococot’ is a new cultivar of false spirea, a shrub grown for use as a landscape plant.

The new Sorbaria arose from a breeding program conducted by the Inventor at a nursery in Boskoop, The Netherlands. The objective of the breeding program was to develop new Sorbaria cultivars with dense and compact plant habits, new foliage colors, and good flowering properties.

The new Sorbaria originated by open pollination in June of 2014 of Sorbaria sorbifolia ‘Sem’ (U.S. Plant Pat. No. 16,336) as the female parent. There were numerous plants of unnamed and unpatented plants of Sorbaria sorbifolia planted in the area. The male parent is therefore unknown. ‘Bococot’ was selected as a single unique plant from the resulting seedlings in 2016 (seedling reference no. 1601-01) with final selection for introduction made in 2019 after a propagation trial.

Asexual propagation of the new cultivar was first accomplished by the Inventor using stem cuttings in summer of 2018 in Boskoop, The Netherlands. Asexual propagation by stem cuttings has determined that the characteristics of ‘Bococot’ are stable and 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 ‘Bococot’ as a unique cultivar of Sorbaria.

• • 1. ‘Bococot’ exhibits a compact, dense and consistent plant habit.
  • 2. ‘Bococot’ exhibits a floriferous blooming habit in summer.
  • 3. ‘Bococot’ exhibits young foliage that is deep pink-red in color.
  • 4. ‘Bococot’ exhibits fruits that are greyed-red in color.

The female parent plant of ‘Bococot’, ‘Sem’ differs from ‘Bococot’ in having a shorter plant height, young foliage that is lighter in color and more grey-orange in color, a less floriferous blooming habit, fruit that is more brown in color, and a more vigorous spreading habit. ‘Bococot’ can be compared to the Sorbaria sorbifolia cultivar ‘Levgreen’ (U.S. Plant Pat. No. 31,202). ‘Levgreen’ differs from ‘Bococot’ in having a smaller plant size, mature foliage that is bright green and tinged with bronze in summer, and a very sparse blooming habit.
