It makes me smile to think that someone who has rented this place (in northern Virginia) in the past started air layering the large camellia at the front corner of the house. There are three branches being propagated, and I haven't checked them yet - but am thinking about doing so before I head back to South Carolina for a week in October. If roots have formed, then I'll take them with me and ask my favorite camellia grower to care for them while I'm in Virginia.
The American Camellia Society describe the process of air layering camellias here.
I'm curious about what camellias I have in my yard here - there are several, and they are decent sized for being this far north. They've probably been here for a good long while. They're definitely japonicas, and if I had to guess, they are older varieties - not the more recent cold hardy introductions. I wouldn't be surprised if they were all the same variety.
I'm glad they're in my yard here.
