It's an Alocasia macrorrhizos. They like a lot of water, but still make sure the drainage is good. They don't sit in water as much as Colocasias can. They also prefer full sun but can cope with a little shade. So if it stays indoors most of the time you should keep it in the brightest area you can. The way yours has grown the temperature must be okay. They are grown for food, especially in Fiji, but most probably also in southern China.

Hi. I know of a few apple cultivars that look something like yours. However, given the time of year, my guess would be Milton, a cross of McIntosh x Yellow Transparent, bred by Cornell's New York Agricultural Experiment Station in the 1920's, sister to Early McIntosh.

I agree it looks a bit like K-31, but at the same time it doesn't. That color is blue green, which isn't typical of K-31. Perhaps it is just a photographic artifact. Also it looks like it has a prominent central vein, as the blades have a distinct fold to them, which isn't typical of tall fescue. Definitely not crabgrass, which is too bad, that's not so hard to deal with. Here's a grassy weed id key that might help. http://www.ipm.ucdavis.edu/TOOLS/TURF/PESTS/grasskey.html

I am having trouble posting a picture. But today I learned that the shrub I am interested in is probably a flowering quince. Thanks, Carolyn
