Marie asked in a comment the other day what the whole mountain garland plant looks like -- pictures being worth a thousand words and all, here is one. It does spring from the ground in a single long stem, not a clump. Now that it's getting bigger -- nearly knee-high -- new stems are branching out from the main stem. It's a lovely, willowy thing, tall and slender, with the flowers held high above the leaves -- so pretty in a mass, I would think.
Speaking of a thousand, Marie's comment was the thousandth on this blog! Many congratulations, and a little something will be winging its way to her shortly!
