Botanical classification: Kniphofia uvaria.
Varietal denomination: ‘Echo Mango’.
The present invention relates to a new and distinct cultivar of Kniphophia uvaria and will be referred to hereafter by its cultivar name, ‘Echo Mango’. ‘Echo Mango’ is a new cultivar of red hot poker or torch lily, a perennial grown for landscape use.
The new cultivar was derived from a controlled breeding program conducted by the Inventor at his nursery in Dahlonega, Ga. The overall purpose of the breeding program is to make selections of Kniphofia with unique flower colors combined with a reblooming habit. ‘Echo Mango’ was selected in the Inventor's trial bed in June 2007 as a single unique plant from amongst the seedlings derived from a cross made in April 2006 between ‘Apricot Surprise’ (not patented) as the female parent and ‘Candle Light’ (U.S. Pat. No. 12,343) as the male parent.
Asexual reproduction of the new cultivar was first accomplished by division by the Inventor in Dahlonega, Ga. in June of 2007. The characteristics of this cultivar have been determined both by division and in vitro propagation to be stable and to reproduce true to type in successive generations.
The following traits have been repeatedly observed and represent the characteristics of the new cultivar of Kniphofia. These attributes in combination distinguish ‘Echo Mango’ from all other selections of Kniphofia known to the Inventor.
-
- 1. ‘Echo Mango’ exhibits an early blooming habit with the first blooms appearing at the end of April to the first part of May in Georgia.
- 2. ‘Echo Mango’ exhibits a reblooming habit with repeat bloom throughout the summer with up to 12 blooms per clump per season.
- 3. ‘Echo Mango’ exhibits semi-evergreen foliage that remains cleaner than is typical of the species.
- 4. ‘Echo Mango’ exhibits a clump-forming habit with upright stems that do not lodge.
- 5. ‘Echo Mango’ reaches a height of 100 cm (40 inches).
- 6. ‘Echo Mango’ exhibits inflorescences that are apricot in color.
‘Echo Mango’ can be distinguished from its parent plants. The female parent, ‘Apricot Surprise’, differs from ‘Echo Mango’ in being shorter in height, in having a habit that tends to flop, and in having flowers that are yellow in color. The male parent, ‘Candle Light’, differs from ‘Echo Mango’ in lacking a reblooming habit and typically averages 3 blooms per season. ‘Echo Mango’ can be distinguished from the species, Kniphofia uvaria, in having a reblooming habit and stems that remain upright. ‘Echo Mango’ can also be compared to the cultivar ‘First Surprise’ (U.S. Plant Pat. No. 16,036). ‘First Surprise’ is similar to ‘Echo Mango’ in its early blooming habit but differs from ‘Echo Mango’ in being shorter in height, in lacking a reblooming habit, and in having inflorescences that are bright orange in color.
The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Kniphofia. The photographs were taken of a 2 year-old plant as grown in a garden in Atlanta, Ga.
The photograph in FIG. 1 illustrates the overall habit and appearance of ‘Echo Mango’ in bloom.
The photograph in FIG. 2 provides a close-up view of the inflorescences of ‘Echo Mango’. The colors in the photograph may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Kniphofia.
The general observations describe plants of ‘Echo Mango’ that were observed for 2 years in a trail garden in Dahlonega, Ga., while the detailed botanical data describe one year-old plants as grown in one-gallon containers in Alpharetta, Ga. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determinations are in accordance with The 2007 R.H.S. Colour Chart of the Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
