Claims
We claim:
1. A new and distinct variety of Osteospermum plant named
`Avalanche` as shown and described herein.
Description
Genus and species: Osteospermum sp.
Variety denomination: `Avalanche`.
BACKGROUND OF THE NEW PLANT
The present invention comprises a new and distinct variety of
Osteospermum, botanically known as Osteospermum sp., and
hereinafter referred to by the variety name `Avalanche`. The new
variety originated from an Osteospermum jucundum (unpatented) and
Osteospermum barberiae (unpatented) hybridization. Cuttings from
the hybridization were rooted, planted and grown out in Denver,
Colo. in August 2002. `Avalanche` was selected in June 2005 based
on its extreme cold hardiness, large, white flowers and compact,
prostrate habit. `Avalanche` was first propagated asexually by
vegetative cuttings in June 2005 in Denver, Colo. and has been
asexually propagated over multiple generations. The present
invention has been found to be stable and reproduce true to type
through successive asexual propagations via vegetative
cuttings.
Plant Breeder's Rights for this variety have not been applied for.
`Avalanche` has not been made publicly available or sold more than
one year prior to the filing date of this application.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing
characteristics of the new variety when grown under normal
horticultural practices in Denver, Colo. 1. Cold hardiness to
-25.degree. F.; 2. Large, white flowers; and 3. Compact, prostrate
habit.
DESCRIPTION OF THE PHOTOGRAPH
This new Osteospermum plant is illustrated by the accompanying
photograph which shows an overall view of a mature plant. The
colors shown are as true as can be reasonably obtained by
conventional photographic procedures. The photograph was taken in
June 2009 of a three-year-old plant in a garden in Denver, Colo.
under conditions, which approximate those generally used in
commercial practice.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `Avalanche`. The data which define these
characteristics were collected from asexual reproductions carried
out in Denver, Colo. The plant history was taken in Spring 2010 on
plants rooted from cuttings stuck in December 2009. The rooted
cuttings were transplanted and planted in larger pots (one gallon
size) in February 2010 in a greenhouse. Color readings were taken
under natural light as well as microscope light. Color references
are primarily to The R.H.S. Colour Chart of The Royal Horticultural
Society of London (R.H.S.), Fifth Edition (2007).

barberiae (unpatented), in that `Avalanche` has white flower and a
compact, short plant habit, while Osteospermum barberiae has
purple-pink flowers and a tall plant habit.
`Avalanche` differs from the commercial Osteospermum variety `Oste
Whitey` (unpatented) in that `Avalanche` is cold hardy to
