This new Ilex variety was found as an openly pollinated seedling of Ilex Hybrid `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 with an upright, dense, pyramidal shape, attractive orange-red fruit, and unusual leaf serrations. As with the parent, the plant of this invention may be advantageously employed as a specimem appointment, in either formal or informal groupings, and is very attractive in mass plantings. The plant serves well in foundation plantings and is adapted for culture as a potted plant. This plant is responsive to pruning and training and may be used in forming dense 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.
SUMMARY OF THE INVENTIONThe following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Poplarville, Miss.
1, Upright, dense and pyramidal in nature.
2, Hardy to Zone 7.
3, Heat and drought tolerant.
4, Fast growth rate under normal fertilization and moisture conditions.
5. Tolerates most soils from moist to dry and from sand to clay.
6. Relatively pest resistant.
7. Very desirable in planters.
8. Makes a good hedge. The short petiole and internode length in addition to the unique arrangement of stiff spines results in a plant which produces an impenetrable thicket.
9. Easy to root from cuttings collected any time of year.
10. Flowers are perfect and can effectively pollinate other forms of Ilex.
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 glossy dark green color with attractive spines.

The parent plant of the new variety `Conive` is Ilex `Mary Nell` which originated from a controlled cross made in 1962 by Joe McDaniel at Tom Dood Nurseries in Semmes, Ala. The female parent was Ilex (cornuta Burfordii`.times.pernyi) `Red Delight`. The selection of Henry Hohman, Kingsville Nurseries, 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. Steven, Oxford, Md. This non-patented plant is comparable to the new plant, however, there are many differences. The flowers of the new variety contain male and female parts which are both functional compared to the Ilex `Nellie R. Stevens` and Ilex `Mary Nell` flowers which have viable ovaries but the anthers produce no pollen. The new variety also has more spines, 5-7 (pairs) compared to 2-3 (pairs) and the spines are much more prominent than those of Ilex `Nellie R. Stevens`. Ilex `Nellie R. Stevens` often has 3 terminal spines, whereas the new variety always has 3 terminal spines. The central terminal spine of the new variety tends to be the same plane as the main leaf blade which is characteristic of Ilex pernyi. The spines of Ilex `Nellie R. Stevens` normally point downward at an angle to the main leaf blade, characteristic of Ilex cornuta.
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 Festive.
Classification:
Botanic.--Ilex Hybrid `Conive`.
Form: Upright, dense and pyramidal.
Texture: Medium to coarse.
Height: 15-20'.
Width: 12-15'.
Growth habit: Upright, dense and pyramidal. Fast growth rate under normal fertilization and moisture conditions.
Foliage: Alternate, simple, evergreen, ovate to lanceolate, and vary in size from 13/4-23/4" long and 11/4-13/4" wide. The margins are serrate with 5-7 pairs of stiff prominent spines. The spines vary in length and width from 1/16 to 7/16". The apex is acute with 3 large prominent terminal spines of equal size. The central terminal spine is in the same plane as the main leaf blade, however, the first, third, and occasionally the fifth pair of spines point upward. All other spines are in the same plane as the main leaf blade or pointing slightly downward. After the 3 large terminal spines the length of the spines usually alternates between long and short beginning with a pair of short spines. The base of the leaf is obtuse.
The peticle is 1/4" long and the internode length is 3/8-3/4". 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 Yellow-Green Group 144A. The lower surface of the immature leaves are Yellow-Green Group 144A 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 slightly less than that of the parent plant.
In 1992, the date of initial spring growth was Mar. 10, in Poplarville, Miss. After the initial 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 is 3/8-3/4" compared to 5/8-11/4" for the parent plant. When grown in light shade the internode length is 3/4-1". As would be expected either plant grown in the 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 14" when grown in shade. After this initial flush we normally trim the plant lightly and the plant then continues to grown about 8" until we trim it a second time in 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. Ilex `Mary Nell` plants grown under identical conditions were also 34" tall and 20" wide at the end of the fall.
Although there are many variables involved it should take about 8-10 years for this plnat to reach a mature height of 15-20' tall and width 12-15'. In the landscape little or no pruning is necessary to produce a dense, upright, pyramidal shrub in full sun. In shade, however, some trimming may be needed to produce the same effect.
Stems: The young shoots and petioles are yellow-Green Group 144A, glabrous, and matte. After one or more years the stems are generally Green-Brown Group 199C, glabrous, and rugose. The pith is solid and uniform.
Flowers: Perfect, small, creamy yellow, inconspicuous, slightly fragrant, borne on previous season's growth from Mar. to May. 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 immature anthers White Group 155D. As the anthers mature and pollen is released the color becomes Yellow Group 3C. 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, 1/4-3/8" diameter, born 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-Nov. in Poplarville, Ms. and persists into the winter. Normally fruit set is moderate.
Culture: Grown 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 anytime of the year
Pest: Non serious.
