Description

Hello, Craigslist.com website community/readers; I would like to identify which species of plant this is. I didn't plant it. It grew on its own, right there. And, I really like it ! It's so thin and it's so eagerly growing, stretching, becoming a very beautiful, very thin, fragile-looking, tree-wanna-be, precious sprout, reaching for the skies! Its amazing to me that it seems to have already started growing many leaves, yet the vast majority of the leaves are so, so thin, yet,...that they resemble certain dainty twigs with the girth of hair-like strands ! (...only the older leaves, at it's base, seem to have filled out entirely) (...and, those more-mature, entirely-grown leaves, seem, to me, to resemble the Eucalyptus tree leaves a bit.) By the way, I had mixed soil from different planters and that particular soil was from those others, then some purchased soil was also part of the mix, and, although I can't say that back then (..last year) if I also dug out some soil from outside, which is something that I have done recently, when I had finally gone to my local thrift store, to pick up that light-brown, long, planter, which I set out to find for this plant/tree, judging that it's roots are likely to reach down very deeply, since it resembles some type of shrub/tree species to me. By the way, all of my other plants/smaller ones, are all indigenous plants who I purchased from a local company. So, those are wild plants who correspond to this geographical region. (I think I shall add a picture of the small planters where I am keeping those.)
