Description

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Anthurium plant, botanically known as Anthurium andreanum, and hereinafter referred to by the cultivar name ‘Red Flare’.

The new Anthurium is a product of a planned breeding program conducted by the Inventor in Schipluiden, The Netherlands. The objective of the program is to create and develop new Anthurium cultivars that have a freely clumping growth habit, strong and vigorous plant growth, attractive spathe color, numerous inflorescences and leaves, and good post-production longevity.

The new Anthurium originated from a cross by the Inventor of the Inventor's proprietary Anthurium andreanum selection code number 90-6 as the female, or seed, parent with the Inventor's proprietary Anthurium andreanum selection code number 90-3 as the male, or pollen, parent. The cultivar ‘Red Flare’ was discovered and selected by the Inventor as a plant within the progeny of the stated cross in a controlled environment in Schipluiden, The Netherlands, on Nov. 5, 1991.

Asexual propagation of the new cultivar by tissue culture has shown that the unique features of this new Anthurium plant are stable and reproduced true to type in successive generations of asexual propagation.

BRIEF 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 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 the cultivar ‘Red Flare’. These characteristics in combination distinguish ‘Red Flare’ as a new and distinct cultivar:

1. Upright and outwardly spreading plant habit.

2. Freely clumping growth habit.

3. Strong roots.

4. Large and durable dark green leaves that are elongated cordate in shape. Dark green color is maintained under conditions of high light.

5. Spathes that are positioned upright and beyond the foliage on strong and erect scapes.

6. Large, durable, glossy bright red spathes.

7. Year-round continuous flowering.

8. Good flowering performance under low light conditions.

9. Resistant to Xanthomonas and Colletotrichum.

10. Tolerant to low and high temperatures.

11. Good post-production longevity.

The new Anthurium can be compared to the female parent, the Inventor's proprietary selection code number 90-6, described as having pink-colored spathes. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of selection code number 90-6 in the following characteristics:

1. Plants of the new Anthurium are more compact than plants of the selection code number 90-6.

2. Plants of the new Anthurium have darker green, narrower and more durable leaves than plants of the selection code number 90-6.

3. Plants of the new Anthurium have smaller spathes than plants of the selection code number 90-6.

The new Anthurium can be compared to the male parent, the Inventor's proprietary selection code number 90-3. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of selection code number 90-3 in the following characteristics:

1. Plants of the new Anthurium are not as compact as plants of the selection code number 90-3.

2. Plants of the new Anthurium have larger, darker green and more durable leaves than plants of the selection code number 90-3.

3. Plants of the new Anthurium have larger spathes than plants of the selection code number 90-3.

The new Anthurium can be compared to the Anthurium cultivar ‘Lady Jane’, not patented. In side-by-side comparisons conducted by the Inventor in Schipluiden, The Netherlands, plants of the new Anthurium differ from plants of the cultivar ‘Lady Jane’ in the following characteristics:

1. Plants of the new Anthurium have darker green and more durable leaves than plants of the cultivar ‘Lady Jane’.

2. Plants of the new Anthurium have larger spathes than plants of the cultivar ‘Lady Jane’.

3. Plants of the new Anthurium and the cultivar ‘Lady Jane’ differ in spathe coloration as plants of the cultivar ‘Lady Jane’ have pink-colored spathes.

4. Plants of the new Anthurium are more resistant to pathogens common to Anthuriums than plants of the cultivar ‘Lady Jane’.
