Arrow-leaved violoet: I think that's it. There are still three tiny ones left, after the one my husband accidentally killed. Two did not flower. I looked it up, and one wildflower page has this to say: "Habitat: dry woods, clearings, rocky areas." Which pretty much describes our hillside. The serviceberry draws a lot of birds when it is in fruit, so we get plenty of volunteers under it. Most of them are not desirable, but it looks like this time we have a winner. It can stay right where it is, and if it thrives I will try to move one or two plants next year.

Weakley's key says that main or middle stem leaves average 3x as long as wide, and have long-tapered bases for .var lanceolata. Main or middle stem leaves average 2x as long as wide, with broadly rounded bases for var. vulgaris. We see more of the upper leaves in your photo. The lower ones do appear shorter, broader, and have more rounded bases. There's even a little understood, third variant (.var hispida) that has stems, petioles, and sometimes lower leaf surfaces densely villous-hispid. The same .var vulgaris parts are only sparingly, and not conspicuously, pilose. All of that said, your plant seems most like .var vulgaris to me.

It's a Hoya, if you post this over in the Hoya forum they could probably tell you which one it is.

"I can upload a pic if someone will explain how" I'm curious, so I'm giving you a link from the faq's of the hot pepper forum that's pretty comprehensive as to how to add photos. It gives more than one option. http://faq.gardenweb.com/faq/lists/pepper/2002072150000611.html Here is a link that might be useful: how to upload photos from hot pepper FAQ's
