| Abstract: |
A Ficus benjamina plant having a laterally dominant growth habit. |
| Claim: |
I claim:
1. A new and distinct cultivar of Ficus benjamina named `Rianne`, substantially as illustrated and described, particularly characterized by a plant with laterally dominant growthhabit. |
| Description: |
BACKGROUND OF THE INVENTION
The present invention comprises a new and distinct cultivar of Ficus benjamina. The varietal denomination of the new cultivar is `Rianne.`
The new variety was discovered as a mutation in a controlled planting of Ficus benjamina Exotica in a greenhouse in Aalsmeer, The Netherlands.
SUMMARY OF THE INVENTION
The new variety is a mutation of the variety Ficus benjamin Exotica and differs significantly in growth habit and appearance from its parent. Whereas Ficus benjamina exhibits a vertical, upright growth pattern, `Rianne` has a substantiallyhorizontal, or laterally dominant habit of growth. Although growth of the new variety will eventually progress vertically, it does so much slower than its parent. For example, where its parent takes six months for a vegetative cutting of 8 cm to reachone meter in height, `Rianne` takes two years. In addition, the growth form of `Rianne` exhibits a zig-zag uneven branching, sometimes branching at about right angles, whereas the parent exhibits a dominant vertical growth pattern with upright multiplebranching. The leaves of the new variety tend to be slightly smaller than the parent, and with alternate ovate-elliptical and acuminate leaf tip. The growth habit of `Rianne` makes it suitable for varied uses, including growing in containers.
The new variety has been asexually reproduced vegetatively by rooted cuttings in Aalsmeer, The Netherlands. Asexual reproduction through succeeding generations has established that the combination of characteristics as herein disclosed for thenew cultivar is firmly fixed and is retained through successive generations of asexual reproduction.
BRIEF DESCRIPTION OF THE ILLUSTRATION
The accompanying illustration shows a specimen of the new cultivar in a photo illustration as true to color as is reasonably possible to make in an illustration of this character, and describes the laterally dominant growth habit.
DESCRIPTION OF THE NEW VARIETY
`Rianne` has not been observed under all possible environmental conditions. The phenotypic expression may vary with variations in environment such as temperature, light intensity and day length. The following observations and descriptions areof plants grown in Aalsmeer, the Netherlands, in a greenhouse. In this description, color references are to The Royal Horticultural Society Colour Chart (R.H.S.C.C.). The terminology used in the color descriptions herein refers to plate numbers in thiscolor chart.
