Description

Botanical designation: Campsis radicans.

Variety denomination: ‘Huitan’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of trumpet creeper that is grown for use as an ornamental landscape plant. The new cultivar is known botanically as Campsis radicans and will be referred to hereinafter by the cultivar name ‘Huitan’.

The inventor selected ‘Huitan’ in 1996 as an individual plant found growing amongst a batch of plants at the inventor's nursery in Boskoop, The Netherlands. The inventor has been interested in the genus Campsis and maintains a collection of named cultivars and unnamed selections which have arisen at the inventor's nursery through open pollination.

The batch of plants from which the inventor selected ‘Huitan’ was raised by the inventor from seed which the inventor collected from a plant of Campsis radicans ‘Flamenco’ (unpatented). This plant had been open-pollinated and the pollen parent was an unknown and unnamed selection of Campsis radicans.

The new Campsis plant ‘Huitan’ is a semi-evergreen flowering vine suitable for use in containers, against walls, trellis, or other structures in the landscape. Cultural requirements include all soil types, light shade or full sun, and regular water. The distinguishing characteristics of the new cultivar ‘Huitan’, are shiny dark-green leaves, many coral-red flowers per shoot, and compact upright habit.

The closest named comparison plant known to the inventor is the seed or female parent Campsis radicans ‘Flamenco’. In general, plants of Campsis radicans are robust and vigorous climbers, with variability in flower coloration between yellow-orange and red and typically achieving heights of at least 10 meters. Campsis radicans ‘Flamenco’ achieves this height also but was selected for the clarity of its orange red flowers. The flowers of ‘Huitan’ are clear red in color and the plant habit of ‘Huitan’ is much more compact. After three season's growth, the height of ‘Huitan’ is approximately 3 meters.

‘Huitan’ was first asexually propagated by the inventor in 1996 in a cultivated area of Boskoop, The Netherlands. The method of propagation used was vegetative cuttings. Since that time in successive generations of asexual reproduction, ‘Huitan’ has remained stable, uniform and true to type.

SUMMARY OF THE INVENTION

The following represent the distinguishing characteristics of the new Campsis cultivar ‘Huitan’. In combination these traits set ‘Huitan’ apart from all other existing varieties of Campsis known to the inventor. ‘Huitan’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

    • 1. Campsis ‘Huitan’ is a perennial that blooms midsummer to fall.
    • 2. Campsis ‘Huitan’ exhibits an upright compact habit.
    • 3. Campsis ‘Huitan’ exhibits many flowers per flowering stem.
    • 4. Campsis ‘Huitan’ produces red trumpet-shaped flowers.
    • 5. Campsis ‘Huitan’ exhibits glossy dark-green leaves.
    • 6. Campsis ‘Huitan’ is a semi-evergreen vine.
    • 7. Campsis ‘Huitan’ is 35 cm. in diameter and 65 cm. in height after one growing season and approximately 3 m in height at maturity.
    • 8. Campsis ‘Huitan’ is hardy to USDA Zone 7.
    • 9. Campsis ‘Huitan’ is an ornamental landscape plant suitable for use on trellis, wall, or as a screen in the landscape.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new Campsis variety ‘Huitan’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘Huitan’.

The drawing labeled as FIG. 1 illustrates an entire two-year-old plant in flower which has been grown out-of-doors in a 1-liter container.

The drawing labeled as FIG. 2 illustrates a close-up view of the flowers.

The drawings were made using conventional techniques and although colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography.

 BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the Campsis cultivar named ‘Huitan’. Data was collected by the inventor in Boskoop, The Netherlands from 12-month-old plants, in September, that were grown out-of-doors in 1-liter containers. The average daytime temperatures were 14° C. to 28° C. with normal outdoor light level, and the average nighttime temperatures were 7° C. to 16° C. Color determinations are in accordance with The 2001 Royal Horticultural Society Colour Chart except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to the species and there are no disease problems known to the inventor. No growth retardants or photoperiodic treatments were applied to the plants.
