ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium hybrid, and hereinafter referred to by the cultivar name Aeighteen.
The new Anthurium is a product of a planned breeding program conducted by the Inventor in Altha, Fla. The objective of the breeding program was to develop early-flowering dwarf pot Anthuriums with attractive spathe colors.
The new Anthurium originated from a cross made by the Inventor in 1993, of a proprietary seedling selection of Anthurium hybrid code number 91-94-2 as the male, or pollen, parent with the Anthurium hybrid cutlivar A2, disclosed in U.S. Plant Pat. No. 10,210, as the female, or seed, parent. The cultivar Aeighteen was discovered and selected by the Inventor in 1994 as a seedling within the progeny of the stated cross in a controlled environment in Altha, Fla.
Asexual propagation of the new cultivar by tissue culture in Altha, Fla. has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations.
SUMMARY OF THE INVENTION
The new Anthurium has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, light intensity, fertilizer rate, irrigation amount and frequency, and/or propagation procedures without, however, any variance in genotype.
The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Aeighteen’. These characteristics in combination distinguish ‘Aeighteen’ as a new and distinct cultivar:
1. Plants of the new Anthurium have a dwarf growth habit making them suitable for 7.5 to 15-cm containers.
2. Plants of the new Anthurium are vigorous.
3. Plants of the new Anthurium are freely flowering, flower year-round and flower exceptionally early; flowers typically develop on plants about 7 months after planting of tissue culture-produced microcuttings.
4. Plants of the new Anthurium have purple-colored glossy spathes and fairly light-colored spadices.
5. Spathes are held above or at the foliage level on moderately strong peduncles.
6. Spathes of plants of the new Anthurium have very good longevity maintaining lavender color for about five weeks. With subsequent development spathes gradually become green, and retain ornamental value for several months past maturity.
Plants of the new Anthurium are distinguished from plants of the parent cultivar A2 primarily in spathe color as plants of the cultivar A2 have pink-colored spathes. In addition, plants of the new Anthurium differ from plants of the cultivar A2 in the following characteristics:
1. Plants of the new Anthurium are less freely branching and have a more open plant habit than plants of the cultivar A2.
2. Mature leaves of plants of the new Anthurium are darker green and slightly glossier than mature leaves of plants of the cultivar A2.
3. Mature leaves of plants of the new Anthurium are more lanceolate, narrower, longer and more upright than mature leaves of plants of the cultivar A2.
4. Plants of the new Anthurium flower earlier than plants of the cultivar A2.
5. Spathes of plants of the new Anthurium are more ovate, flatter, less puckered, glossier and narrower than spathes of plants of the cultivar A2.
6. Under high light and high temperature conditions, spathe color of plants of the new Anthurium tends to fade earlier than spathe color of plants of the cultivar A2.
7. Peduncles of plants of the new Anthurium are thinner, weaker and usually longer than peduncles of plants of the cultivar A2.
Plants of the new Anthurium are distinguished from plants of its sibling cultivar Atwelve, disclosed in U.S. Plant patent application Ser. No. 09/292,198, primarily in spathe color as plants of the cultivar Atwelve have red-colored spathes. In addition, plants of the new Anthurium differ from plants of the cultivar Atwelve in the following characteristics:
1. Young leaves of plants of the new Anthurium are green in color whereas young leaves of plants of the cultivar Atwelve are between brown and green in color.
2. Mature leaves of plants of the new Anthurium are more lanceolate, narrower, longer and more upright than mature leaves of plants of the cultivar Atwelve.
3. Plants of the new Anthurium flower slightly earlier than plants of the cultivar Atwelve.
4. Spathes of plants of the new Anthurium are more ovate, flatter, less puckered, glossier and narrower than spathes of plants of the cultivar Atwelve.
5. Under high light and high temperature conditions, spathe color of plants of the new Anthurium tends to fade earlier than spathe color of plants of the cultivar Atwelve.
6. Peduncles of plants of the new Anthurium are thinner, weaker and usually longer than peduncles of plants of the cultivar Atwelve.
