Abstract

A new and distinct cultivar of Crocosmia plant named ‘Hot Spot’, characterized by its upright plant habit; strong, and sturdy and resistance to lodging; moderately vigorous to vigorous growth habit; freely flowering habit; numerous and relatively large and upward-facing yellow orange and red-colored flowers; and good garden performance and winter hardiness.

Description

Botanical designation: Crocosmia X hybrida.

Cultivar denomination: ‘HOT SPOT’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Crocosmia plant, also referred to as Montbretia, botanically known as Crocosmia X hybrida and hereinafter referred to by the name ‘Hot Spot’.

The new Crocosmia plant is a product of a planned breeding program conducted by the Inventor in Carisbrook, Newport, The Isle of Wight, United Kingdom. The objective of the breeding program is to create new upright and strong Crocosmia plants with large attractive upward-facing flowers, a long flowering period and winter hardiness.

The new Crocosmia plant originated from a cross-pollination made by the Inventor in Carisbrook, Newport, The Isle of Wight, United Kingdom on Jul. 10, 2007 of two unnamed seedling selections of Crocosmia X hybrida, not patented. The new Crocosmia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Carisbrook, Newport, The Isle of Wight, United Kingdom on Aug. 14, 2009.

Asexual reproduction of the new Crocosmia plant by divisions in a controlled greenhouse environment in Carisbrook, Newport, The Isle of Wight, United Kingdom since the spring of 2010 has shown that the unique features of this new Crocosmia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Crocosmia have not been observed under all possible combinations of environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Hot Spot’. These characteristics in combination distinguish ‘Hot Spot’ as a new and distinct Crocosmia plant:

    • 1. Upright plant habit; strong, sturdy and resistance to lodging.
    • 2. Moderately vigorous to vigorous growth habit.
    • 3. Freely flowering habit.
    • 4. Numerous and relatively large and upward-facing yellow orange and red-colored flowers.
    • 5. Good garden performance and winter hardiness.

Plants of the new Crocosmia differ primarily from plants of the parent selections in the following characteristics:

    • 1. Plants of the new Crocosmia are more freely flowering than plants of the parent selections.
    • 2. Plants of the new Crocosmia have larger flowers than plants of the parent selections.
    • 3. Plants of the new Crocosmia are more winter hardy than plants of the parent selections.

Plants of the new Crocosmia can be compared to plants of Crocosmia X hybrida ‘Paul's Best Yellow’, not patented. In side-by-side comparisons, plants of the new Crocosmia differ primarily from plants of ‘Paul's Best Yellow’ in flower color as plants of the new Crocosmia have yellow orange and red-colored flowers whereas plants of ‘Paul's Best Yellow’ have yellow-colored flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Crocosmia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Crocosmia plant.

The photograph on the first sheet comprises a side perspective view of typical flowering plants of ‘Hot Spot’ grown in an outdoor nursery.

The photograph on the second sheet is a close-up view of typical inflorescences of ‘Hot Spot’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations and measurements describe plants of the new Crocosmia grown during the summer in an outdoor nursery in Hillegom, The Netherlands. During the production of the plants, day temperatures ranged from 16° C. to 30° C. and night temperatures ranged from 8° C. to 20° C. Plants were one year old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
