Abstract

A new double-flowered Impatiens walleriana named ‘TiLipII’, producing light pink flowers; dark green foliage; strong peduncles and pedicels; flowers held above or beyond the foliage; freely branching; medium vigorous mounded growth habit.

Description

Latin name of the genus and species and variety denomination: Impatiens walleriana plant and known by the cultivar name ‘TiLipII’.

BACKGROUND—FIELD OF INVENTION

The present invention relates to a new and distinct cultivar botanically known as ‘Impatiens walleriana’ and by the cultivar name ‘TiLipII’, which is shown in the photograph accompanying this specification.

The cultivar was developed and selected in a controlled breeding program in a controlled environment in Broadbent, Oreg. by the inventors, Harlan Cosner and Sue Cosner, as described herein. The plants may be used in landscaping, window, and hanging baskets and flower gardens. The plants are generally classed as an annual bedding plant.

BACKGROUND—DESCRIPTION OF THE PRIOR ART

The closest known cultivar is ‘TiLip’ U.S. Plant Pat. No. 12,855.

COMPARISON

The impatiens plant of the present invention differs from prior plants, namely ‘TiLip’ in at least the following ways:

1. ‘TiLipiII’ is more vigorous and produces a larger plant than ‘TiLip’.

2. The flower color of ‘TiLipII’ is 69B compared to ‘TiLip’ which is 62B to 62C.

3. See accompanying comparison chart.

These and other distinguishing characteristics will be apparent to persons skilled in the art.

BACKGROUND—DISCOVERY and PARENTAGE

The present cultivar was developed by standard cross-pollination. The pollen producing parent was a double-flowered ‘Impatiens walleriana’ coded BR-A-269, and the seed producing parent was a semi-double-flowered impatiens coded BR-A-53. The seed parent's flower color was light pink, and the pollen parent's flower color was a blush white. Neither parent is patented.

The cross was made in the breeders' controlled breeding program at Broadbent, Oreg. The first asexual reproduction was also made at Broadbent, Oreg. Successive asexual generations produced from cuttings with two or more leaves have shown the cultivar to be stable.

The cultivar is unique either in one or a combination of the characteristics described herein. It is a new, complete double-flowered ‘Impatiens walleriana’ producing bright purple flowers; dark green foliage; compact growth habit; fully double flowers held above or beyond the foliage on strong peduncles and pedicels; and a compact mounded growth habit.

Appearance and form of mature plant:

Plant form and habit.—Mounded and of medium vigor.

Plant size.—Plants mature at about 15 cm in height and about 30 cm in width. Both of these measurements are a function of age, environmental and cultural practices, and can vary accordingly.

Rooting description.—The roots are fibrous and well-branched.

Rooting ability.—Easy; no hormones needed.

Branching habit.—Plants are self-branching. Stems are strong and freely produced. The number of stems depends upon cultural practices, age of stems used as cuttings and the number of growth buds present on the cutting when stuck.

Stems.—Stems are produced freely, no pinching is needed to induce branching. Color is close to 146A with small dark reddish markings of a very hard to determine color but which appear close to 183A to 183B. At maturity stem: diameter measures about 4 mm at the internodes; internode generally about 0.5 cm or longer.

Foliage shape and size.—At least 3.5 cm. wide; about 1.5 cm. deep. The largest petals are generally comprised of two petals fused at the base, and each is generally at least 1.5 cm. wide and 1.5 cm. deep; obovate to exaggerated obovate in shape with cuneate to obtuse base, entire margin, and obtuse to retuse apex. The above measurements refer to the average flowers. The size of the flowers will generally be much larger during spring and summer.

Foliage color.—Adaxial surface is closest to, but does not match any color in the chart but is closest to 137A; Abaxial surface does not match any color in the chart, but is closest to 146B; adaxial surface venation is close to 146A; Abaxial surface venation, main vein does not match, but is closest to 146B, lateral veins are closest to 146A.

Foliage texture.—Smooth and flat.

Petioles.—Petioles are about 2.5 cm long, half round, flat to slightly convex on upper surface which is about 3.5 mm wide, depth of about 2.5 mm. Color on adaxial surface is close to 146D with very tiny reddish markings that appear close to 183B; Abaxial surface color is closest to 146C to 146D.
