Shen Yinchun 沈荫椿, Yuri Panchul, Sayaka Panchul and children. Sunnyvale, California, November 10, 2007.

I have a collection of more than 100 sasanquas and other camellia plants, not including my own seedlings. I grow my plants on my backyard in Sunnyvale, California, mostly in containers. I am a member of The International Camellia Society, American Camellia Society, San Francisco Peninsula Camellia Society and The Camellia Society of Santa Clara County.

In addition to this site I write about sasanquas and other plants in paper publications. My articles appeared in The American Camellia Yearbook – a prestigious publication by The American Camellia Society; Camellia News – the journal of Camellias Australia; Sun Camellias – a book published by the Southern California Camellia Society; and three Russian magazines – Tsvetovodstvo (Цветоводство, Ornamental Horticulture), V Mire Rasteniy (В Мире Растений, The World of Plants) and The New Times (Новое Время). I also contributed information and photo pictures of camellias to the articles written by other people in The Camellia Journal, The Los Angeles Times, The San Francisco Chronicle and a book Camellias written in Chinese by Shen Yinchun 沈荫椿 (Y.C.Shen).

My main occupation is engineering. I got some publicity in the area of Electronic Design Automation (EDA) as a CTO (Chief Technology Officer) of a Silicon Valley company called C Level Design, that I founded back in 1996 and that was sold to Synopsys in 2001. Right now I work in MIPS Technologies (2009) – a company founded by Stanford President John Hennessy. Since 1980s MIPS has been a pioneer in modern processor design – MIPS processors were used in Silicon Graphics computers, Sony TV sets, video game consoles, photo cameras, laser printers and numerous other devices.

  • HI
    I was wondering if you’d mind if I used a few of your Camellias Susanquas photos in a gardening calendar I am designing. I am happy to provide a photo credit if you would so permit.
    I look forward to your response.


  • Bonjour,

    We are a french nursery and we love camellia sasanqua.

    Please take a look at our website and perhaps add it in your list of nurseries !

    Bravo for your blog !

    Thank you! I will add your nursery to the list!


  • Dear Mr Panchul,
    I am a very dedicated reader of your site and, of course, a camellia-lover (almost 200 plants). As far as your interesting new seedling is concerned, just today one of my seedlings (4 year-old) has given the very first two flowers which look a lot similar to yours. Isn’t funny?


  • Thank you! Your seedling does look promising!


  • Thank you for a detailed and well-documented resource. I wonder if you can help me understand (I’m a very green newbie) why the Ju Dee camellias at the Loganville Grower’s Outlet from Tom Dodd stock claim to grow to 24-26″, but the Ju Dee camellias at Home Depot are marked to grow 6-8′ tall? I’m looking for camellias for my small, small garden – is Ju Dee (I also bought Lauren and Ruth Grahams via Tom Dodd from Loganville) going to fit the bill?

    Thank you kindly,

    Bethlehem, GA

    Any Camellia japonica, including ‘Ju Dee’, given sufficient time can grow into a large tree. If what you said is true than I guess Loganville Grower’s Outlet people are either confused or untrustworthy. And by the way, this applies to Home Depot as well.


  • May I suggest to Kim the tremendously slow-growing “Night Rider” cultivar? Besides its unusually deep dark-red (with blackish hues) small flowers, this camellia takes so much time before becoming a large shrub.


    Kim reply on August 16th, 2011 1:03 pm:

    Thank you kindly for your response – I’m sorry I hadn’t seen this before. I will be delighted to look for the “Night Rider” cultivar and again, thank you for your suggestion.


  • Dear Mr Panchul,
    We are a group of Fractal Artists who are building an exciting new website.—- showing the remarkable correlation between fractals and organic material, mainly flowers and vegetables .

    May we have your permission to use the image “Winter rose,” one of your stunning photographs? I have attached the link we would like to use to illustrate comparisons. You can see we are still at the raw and grisly state just now.

    Our aim is not one of financial gain, but to show beauty at its best in both fields. We will of course attribute you as the creator of the picture if you so agree.

    Yes, you can use it. Thank you.


  • Hi Yuri, I am a horticultural teacher living in the Blue Mountains, west of Sydney Australia. I have had a special interest in genetic leaf variegation and leaf mutations in Camellias for many years. The image of the Stars & Stripes sasanqua flower is beautiful. I wanted to ask if you have that plant growing and if it produces seeds? I have not seen it listed in Australian nurseries. Thanks, Ken


  • Hi sir
    I wonder if you senf me about your publication such as magazines or articles. I want to know Russian horticulture technics.
    Thanks a lot.


  • Dear Mr. Panchul,
    I have enjoyed your websites and your contributions to gardenweb. Since your are from the Bay area perhaps you might be able to help me find more information on a camellia that is very intriguing, but impossible to find. I would love to find ‘red leaf bella’ also known as ‘hongye beila’. http://www.americancamellias.org/assets/Journal-1209-China%20Red.pdf
    I cannot find it anywhere and the referenced article is not very current. Do you know if this cultivar is available in the US? And if so, where might I find it?

    This person seems to think it is available: http://forums.gardenweb.com/forums/load/camellia/msg040156131858.html

    I would love to plant one in my yard. Thank you so much,


  • Hi Yuri,

    I’m from Toronto, Canada. Do you sell Hardy Camellia seeds?

    Thank you very much for your articles. Very interesting and helpful.

    Best Regards,


    Yuri Panchul reply on January 10th, 2013 3:34 pm:


    No, I don’t sell seeds. You can probably buy seeds from http://camforest.com

    Thank you,
    Yuri Panchul


  • I was very interested to read that John Wang has successfully used Octapetala in crosses. Others I have corresponded with have had no success. I would be very interested in corresponding with John Wang and with Yuri regarding camellia hybridizing.

    My main breeding goals are camellias that reach peak bloom from December through February with good flower substance and disease resistance. Almost all sizes from 2″ on up are of interest. In addition, but of secondary emphasis in my breeding program are fragrance and yellows, and different patterns like borders and stripes.
