| Description: |
BACKGROUND OF THE INVENTION
This invention relates to the discovery of a new and distinct variety of evergreen azalea plant named `Sweet Lorraine` which was discovered by me as a naturally occurring branch sport of an azalea plant named `Wakaebisu` (unpatented), a knowncultivar of the genus Rhododendron and of the indicum species, also known as a Satsuki variety.
At the time of my discovery referred to above, I was growing in my nursery, located in Metairie, La., an azalea named `Wakaebisu`. In the course of my care and cultivation of this plant, my attention was attracted to a branch that wassubstantially different from the rest of the plant. This branch was taken and used as a cutting and had the following qualities. The leaf size was significantly smaller, being 1/2 to 1/4 the size of the parent. The internodal space was significantlyshorter than the parent. From the subsequent measurements I took, I determined that the average internode was 1/8 of an inch, which is four times less than the natural internode of the parent. As a result, the foliage is more dense. The sport also hada very unique growth habit that resembled a witches broom. Continued study and observation of the discovered sport and its progeny showed that during the growing season vegetative buds form and swell, resembling juvenile flower buds. Upon opening,branches break very rapidly from the terminal buds and subsequently and sporadically from axillary buds (without pruning). Sporadic and frequent growth (resembling a witches broom) rapidly develops into desirable branching with miniature foliage. Theresult of this unique growth habit is a plant which is more characteristic of a mature plant exhibiting an aged appearance. Flowers of the new plant are identical in shape and color to the parent, although it does occasionally produce smaller blooms(about 11/2 inches) than the parent's typical 2-21/2 inch blooms. This appears to be the result of the competition within the system from the unusual number of flower buds. This quality allows for the new plant to have an abundance of flowers that morefully cover the plant, than the parent.
Asexual propagation by cuttings over several generations performed by me at my nursery located in Metairie, La., (and in Covington, La.) proved that the unique characteristics of `Sweet Lorraine` as stated within, which distinguishes it from itsparent and other varieties known to me, are new and distinct, fixed and true and can be reproduced.
The ultimate size is unknown, as no plant has yet reached maturity. Three year old plants have reached heights of 27 inches with a width of 23 inches. Because this new variety has miniature foliage, a dense growth habit, and excessive branchingthat forms quickly due to its qualities, it is an excellent new plant for the bonsai market. `Sweet Lorraine` can be trained to any tree form (or grown as a shrub). With pruning, the foliage becomes even smaller and extremely dense in a short timeframe. This new plant has a general attractiveness particularly suited for the bonsai market and extremely desirable for the commercial market as well.
BRIEF DESCRIPTION OF THE PHOTOGRAPHS
FIG. 1 is a photograph that shows flower size.
FIG. 2 is a photograph that shows the overall appearance of both the new variety (on the right) and the parent (on the left) in a side by side view for comparison.
FIG. 3 is a photograph showing a close up of the unique branching.
Actual leaf and inflorescence colors may differ from leaf and inflorescence colors in the photographs due to light reflectance.
DESCRIPTION OF THE PLANT
The descriptive matter which follows pertains to the new variety `Sweet Lorraine` when grown in the vicinity of Covington, La., under full sun to partial shade and is believed to apply when the new variety is grown under similar conditions ofsoil and climate elsewhere, the soil type being 50% decomposed pine bark and 50% haydite (fired clay). Color determinations are based on the Munsell Book of Color.
GENERAL CHARACTERISTICS
The plant is a low and spreading shrub with miniature leaves and demonstrates the ability to spontaneously produce foliage buds without pruning, hence branches heavily and is more vigorous than the parent. The new plant flowers profusely in Mayand June and is an ideal plant for the bonsai market as well as other commercial markets.
Origin: Naturally occuring branch sport.
