Seedling yuri_panchul_2003_024_oleifera evaluation – unsuccessful

I decided to start writing down all seedling evaluations – even for very poor seedlings. I think it will help me to develop successful evaluation criteria.

I got the seed for yuri_panchul_2003_024_oleifera not from a plant in my garden, but from Camellia Forest Nursery in 2003. The resulting seedling was blooming first time 2009.09.02. The flower is a typical wild-type C. oleifera flower, nothing special. The bush shape is spreading, branches are flexible and have long internodes – this is not practical unless you plant to grow an espalier. Leaves are not shiny and way too large for my taste – the largest leaves are approximately 110×60, 100×60 and 90×70 mm (4.3 x 2.4, 4.0 x 2.4, 3.5 x 2.8 inch). The root system is pretty strong.

The plant was grown in somewhat poor condition – it was too dry during one of the heat waves that coincidentally happened during the period of active growth back in April-May. As a result some leaves are deformed. The plant is also root bound but this can be easily corrected by proper root pruning. There are some slugs living at the bottom of the container – this is natural because the container was standing on a plastic shelf lying on the ground. The damage from these slugs appear to be very minor.

The conclusion. This plant should be used as a rootstock during next February. The root bound problem can be corrected after 1 year.

Camellia grijsii

This month The International Camellia Society put two of my camellia photo pictures to the front page of their website. One is a picture of Camellia japonica ‘Kamo Honnami’ (see their website), and another is a picture of Camellia grijsii, a species related to C. sasanqua:

Camellia grijsii (长瓣短柱茶 in Chinese) Hance (1879) is a wild species of section Paracamellia. It is related to C. sasanqua, C. oleifera and C. kissii. It was collected in 1861 in Fujian by C.F.M. de Grijs. It is distributed in China (Fujian, Hubei, Sichuan, Guangxi) and used for a high-quality oil production. C. grijsii is closely related to another species – C. yuhsienensis, that is a parent of a popular cultivar ‘Yume’.

I got my two plants of C. grijsii from Nuccio’s Nurseries. The first one (shown above) has single white flowers and the second one is a double-flowered Chinese cultivar called ‘Zhenzhucha’:

Camellia grijsii has great hybridizing potential. Two plants in my garden have small leaves with impressed veins and very columnar shape. I believe there are also varieties with larger leaves, but I am specifically interested in small-leaved cultivars.

Another great feature of C. grijsii is its cluster-flowering habit. However in my garden C. grijsii flowers from January to March, so it will be a challenge to cross it with Fall-flowering sasanquas. Probably I will have to store some pollen from sasanquas in refrigerator for a couple of months.

Another problem is chromosome number. According to Kondo and his associates it has a variety of chromosome numbers 2n = 30, 60, 75 and 90 (see the reference in Collected Species of the Genus Camellia, an Illustrated Outline by Gao Jiyin, Clifford R. Parks and Du Yuequiang).
