Latest New World Plants USA Patents:
The present invention relates to a new and distinct cultivar of Chamelaucium (Waxflower), botanically known as an interspecific Chamelaucium hybrid, and hereinafter referred to by the cultivar name Blondie.
The new cultivar is a product of a planned and controlled breeding program conducted by the inventors in Coorow, Western Australia, Australia. The new cultivar originated from a deliberate cross by the inventors between two different species of the genus Chamelaucium. An unnamed selection of Chamelaucium megalpetalum was used as the female or seed parent and the Chamelaucium uncinatum cultivar Purple Pride (not patented) was used as the male or pollen parent. Twenty days after the cross-pollination, the immature seed pod was harvested and the developing embryos were aseptically dissected and transferred onto a nutrient agar-based medium for further development. Mature plants developed from these dissected embryos. The cultivar Blondie was discovered and selected by the inventors as a flowering plant within the progeny of the stated cross in a controlled environment in Coorow, Western Australia, Australia.
Asexual propagation of the new cultivar by cuttings taken at Coorow, Western Australia, Australia, and Escondido, Calif., has shown that the unique features of this new Chamelaucium plant are stabilized and reproduced true to type in successive generations of asexual propagation.
The following traits have been repeatedly observed and are determined to be the unique characteristics of the new Chamelaucium. These characteristics in combination distinguish Blondie as a new and distinct cultivar:
1. Strong and erect flowering stems.
2. Upright and semi-open growth habit.
3. Dense terminal floral display.
4. Red purple flower bud color.
5. Light creamy white flower color.
6. Good postharvest longevity.
The new Chamelaucium differs from its seed parent, the selection of Chamelaucium megalopetalum, in the following characteristics:
1. Plants of the new Chamelaucium flower faster than plants of the seed parent.
2. The flower bud color is red purple on plants of the new Chamelaucium whereas the flower bud color on plants of the seed parent is red.
3. The floral tubes of the new Chamelaucium are narrow, prominently fluted, and flared compared to the floral tubes of the seed parent.
4. Plants of the new Chamelaucium have more flowers per stem and appear more dense and full than plants of the seed parent.
5. Plants of the new Chamelaucium have broader flowering stems compared to plants of the seed parent.
The new Chamelaucium differs from its pollen parent, the Chamelaucium uncinatum cultivar Purple Pride, in the following characteristics:
1. The flower bud color is red purple on plants of the new Chamelaucium whereas the flower bud color on plants of the pollen parent is dark red.
2. The petal color of the new Chamelaucium when opening is white compared to the purple petal color of Purple Pride. At maturity, the petal color of the new Chamelaucium remains white whereas the petal color of Purple Pride is purple. The floral tube color is also different, as the floral tube of the new Chamelaucium is green and the floral tube of Purple Pride is red brown. The floral tube is more narrow and prominently fluted on plants of the new Chamelaucium compared to plants of Purple Pride.
3. Plants of the new Chamelaucium have more flowers per stem and appear more dense and full than plants of Purple Pride.
The new Chamelaucium can be compared to the Chamelaucium cultivar Revelation, disclosed in U.S. Pat. No. P.P. 8,791. Plants of Blondie differ from plans of Revelation in the following characteristics:
1. Plants of the new Chamelaucium have shorter internodes, smaller leaves, and shorter peduncles than plants of Revelation.
2. The flower bud color is red purple on plants of the new Chamelaucium whereas the flower bud color on plants of Revelation is dark red. The floral tube color at the distal end is green on plants of the new Chamelaucium and the floral tube color at the distal end is purple brown on plants of Revelation.
3. The petal shape of the new Chamelaucium is obovate whereas the petal shape of Revelation is round.
4. The petal color of the new Chamelaucium at maturity is white compared to the light violet petal color of Revelation.
5. Plants of the new Chamelaucium have narrow floral tubes compared to plants of Revelation.
A detailed comparison of the new Chamelaucium, its parents and Revelation plants appears in Chart A at the end of the specification.
The new Chamelaucium plant has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature and light level, without, however, any variance in genotype.
The accompanying colored photographs show typical specimens of the vegetative growth and flowers of the new Chamelaucium plant, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. The first photograph comprises a side perspective view of typical flowering stems of the new Chamelaucium plant grown in Escondido, Calif. This photograph shows the upright and semi-open growth habit of flowering stems of the new Chamelaucium.
The second and third photographs comprise close-up views of the new Chamelaucium's flowers showing the cultivar's unique petal colors that change with the development of the flower.
In the second photograph, flower buds are red purple; and as the flowers open, the petal color is a light creamy white with a light pink blush.
In the third photograph, flowers shown are mature and petal color is light creamy white.
The following observations, measurements, values, and comparisons describe plants grown in Escondico, Calif. Values representing size of plants, flowers and foliage are averages of plants produced under standard commercial cultural practices. Color references are made to The Royal Horticultural Society Colour Chart except where general terms of ordinary dictionary significance are used.
