Don't know for sure, Mike, but there were some selections bred & selected at the National Arboretum - you might start looking there to see if there's any info on their website(I presume they have one).

Hi, try this link http:/www.camellias.acs.com/index2.html
Not positive, but I think they were developed at the university of North Carolina. American Camellia soc. will tell you, they know most everything. Good luck!

Try this link. They provide a lot Cam. vars.
Some of them are realy hardy, hardy to 6A, such as
snow flurry and winter's intclude.

The most cold hardy seem to bloom in late fall until frost.

Cam Forest is best, as ermazi said.

Agree - Camellia Forest is a wonderful place to order from. It's owned by Dr. Clifford Parks and his wife. Dr. Parks is a retired botanist. They sell the Ackerman varieties as well as many that Camellia Forest has bred.

I am in Stamford inland away from the water .. I have have had several of the hardy camellias for several years now. Ackerman hybrids and star series . they are growing fine ..problem is that they are not ready to bloom until a week after our first hard freeze .

.they set many buds but they are frozen off first every year .. I have a japonica. large flowered one that blooms in the spring, so its buds never make it thru the winter .. they need to do a little fine tuning to get them to bloom sucessfully in this area
