Abstract

A new and distinct variety of Ilex plant found as an openly pollinated seeding of Ilex Hybrid `Mary Nell`. The new variety expresses a very high concentration of anthocyanin in new growth which matures to a semi-glossy green color. This plant is superior in development of a dense, upright, pyramidal shaped canopy with attractive spiny leaves and orange-red fruit.

Description

BACKGROUND OF THE INVENTION
This new Ilex was found as an openly pollinated seedling of Ilex `Mary Nell`, an unpatented variety, maintained in the Evergreen Nursery at Poplarville, Miss. The seedling was found in May, 1989. The new and distinct Ilex Hybrid plant of this invention comprises a novel and valuable holly plant of erect pyramidal habit and attractive reddish-purple new growth. The new growth of this plant is interestingly and clearly red due to anthocyanin, which is of distinctly higher concentration than in the parent variety. As with the parent plant the plant of this invention may be advantageously employed as a specimen appointment, in either formal or informal groupings, and is very attractive in mass plantings. This plant is responsive to pruning and training and may be used in forming dense, attractive hedges, and maintained without an excessive amount of care.
Asexual propagation of the new plant by cuttings has been under Mr. Magee's direction at the same location. Several generations of the new plant have been evaluated and the distinctive characteristics of the plant have remained stable.
SUMMERY OF INVENTION
The following are the most outstanding and distinquishing characteristics of this new cultivar when grown under normal horticultural practices in Poplarville, Miss.
1. Dense, upright, and pyramidal, becoming rounded with age.
2. The Reddish/Purple color of the new foliage is unique and offers a novel and strikingly appealing contrast of new foliage to old foliage in plants of this market class.
3. Hardy to Zone 7.
4. Heat and drought tolerant.
5. Fast growth rate under normal fertilization and moisture conditions.
6. Tolerates most soils from moist to dry and from sand to clay.
7. Relatively pest resistant.
8. Makes a very good hedge or screen.
9. Easy to root from cuttings collected any time of year.
10. Very desirable in planters.
11. Produces attractive orange-red fruit in the fall which persist into the winter and may result in bird visitation.
12. Has the ability to be sheared and trimmed to be kept within prescribed limits.
13. Mature leaves are a semi-glossy rich green color with attractive spines.
14. Easily trained into a small tree.

______________________________________
The parent plant of the new variety `Conin` is Ilex `Mary Nell` which originated from a controlled cross made in 1962 by Joe McDaniel at Tom Dodd Nursery in Semmes, Ala. The female parent was Ilex (cornuta `Burfordii`×pernyi) `Red Delight`, a selection of Henry Hohman, Kingsville Nursery, Kingsville, Md. The male parent was Ilex latifolia. Ilex `Mary Nell` was named in 1981 by Thomas H. Dodd, Jr. after Joe McDaniel's wife.
Ilex Hybrid `Nellie R. Stevens`, which is very popular in the industry, is a hybrid between Ilex aquifolium and Ilex cornuta. It was released by G. A. Van-Lennep, Jr., St. Michael, Md. in 1954. It is named for the owner, Nellie R. Stevens, Oxford, Md. This non-patented plant is comparable to the new plant, however, there are many differences. The immatures foliage of the new variety is Grey-Purple Group 187A compared to Yellow-Green Group 144A of Ilex `Nellie R. Stevens`. The new variety also has more spines 5-7 compared to 2-3.
It is from the openly pollinated seedlings of the Ilex `Mary Nell` plant that I found the new plant. This new variety will be sold under the trademark Robin.
Classification:
Botanic.--Ilex Hybrid `Conin`.
Form: Dense, upright, and pyramidal, becoming rounded with age.
Texture: Medium to coarse.
Height: 15-20'.
Width: 12-15'.
Growth habit: Upright, dense, and pyramidal shrub or small tree. Fast growth rate under normal fertilization and moisture conditions.
Foliage: Alternate, simple, evergreen, ovate to lanceolate, and vary in size from 25/8-33/4" long and 11/8-17/8" wide. The margins are slightly convex and serrate with 5-7 pairs of prominent spines.
The spines vary in length and width from 1/16 to 1/2". The apex is acute and triangular with 3 prominent spines. The terminal spine is slightly large than the next pair and points downward at an angle to the main leaf blade. Spines alternate between long and short after this first larger pair. The base of the leaf is acute. The petiole is 1/4-3/8" long. Mid-veins and laterals are impressed on the upper leaf surface and the mid-veins are prominent on the underside. The upper surface of the immature leaves are glossy, glabrous, and are Greyed-Purple Group 187A.
The lower surface of the immature leaves are Greyed-Purple Group 186B and matte. As the leaves mature the upper surface becomes Green Group 139A and the lower leaf surface becomes Yellow-Green Group 146C. This mature leaf color persists through the winter. The degree of glossiness of the mature leaf is less than that of the parent plant.
In 1992, the date of initial spring growth was March 10, in Poplarville, Miss. After the spring flush there was almost continuous growth until fall ending Oct. 22, also in Poplarville, Miss. This growth pattern was identical to the parent plant. When grown in full sun, the internode length of this plant and the parent plant is 5/8-11/4". When grown in light shade the internode length is 11/4-11/2". As would be expected either plant grown in shade results in a taller less dense plant with larger leaves.
The average length of terminal growth of the initial spring flush is about 12" for a plant in full sun and about 14" when grown in shade. After this initial flush we normally trim the plant lightly and the plant then continues to grow about 8" until we trim it a second time in the early fall. The fall growth of about 10" then hides the cut limbs. We finish in the fall with a three gallon plant about 34" tall and 20" wide. I have not noticed a difference in vigor between this plant and the parent. Although there are many variables involved it should take about 8-10 years for this plant to reach a mature height of 15-20 feet and width of 12-15 feet. In the landscape little or no pruning is necessary to produce a dense and pyramidal shrub in full sun. In shade, however, some trimming may be needed to produced the same effect. The lower limbs can be removed to produce a small tree with attractive gray-brown bark.
Stems: The young shoots and petioles have a pronounced purple pigmentation, Greyed-Purple Group 187A, and are matte. As the stems mature they become Yellow-Green Group 144A. The stem tips (1/2-1") and petioles retain the purple pigmentation into the winter. After one or more years the stems are generally Grey-Brown Group 199C, glabrous and rugose. The pith is solid and uniform. Young and older stems are densely branched.
Flowers: Small, creamy yellow, inconspicuous, slightly fragrant, borne on previous season's growth from March to May. Flower structure of this plant is identical to that of the parent plant. Buds are globular, Yellow-Green Group 144A, and without foliaceous appendages. Flowers are clustered in the leaf axils and are 4-merous. Unbranched pedicels are about 1/4" long and Yellow-Green Group 144A. The four ovate petals are arranged regularly, united at the base, and imbricate in bud. The ovary protrudes from the receptacle and is Green Group 143A. There are four stamen with underdeveloped anthers which are White Group 155D. No pollen is produced. Blooms are small to medium in size, Yellow Group 2D, 3/8" diameter, and last on the plant in the garden 2-4 days.
Fruit: Drupaceous, globose, 3/8-7/16" diameter, borne fasciculate with 2-5 fruits on short unbranched pedicels 1/4" long. Each fruit contains 4 pyrenes. Matures to Orange-Red Group 33A in mid-November in Poplarville, Miss. and persists into the winter. Normally fruit set is not heavy.
Culture: Grows well in a wide range of conditions and tolerates sun to part shade. Grows in nearly any soil type, from moist to very dry and sand to clay. Responds well to mulching and medium applications of fertilizer; prefers ph 5 to 6.5. Little pruning is needed. Can be sheared. Propagated with semi-hardwood cuttings any time of year.
Pests: None serious.
