Looks like Four O' Clock (Mirabilis jalapa)

Error: It's "euphorbia," not "euphoria." (Wish I could edit my post if I discover an error later.) And I found out that, not surprisingly, it's closely related to the poinsettia and sometimes called " Poinsettia dentata." Toothed spurge (Euphorbia dentata) is a member of :  Euphorbia, genus Euphorbia  The Euphorbiaceae are a very large genus of diverse plants all of which have milky juice It is an annual weed of northeastern North America and the Southeastern Yukon (but it obviously grows in the Pacific NW US too). More info here: Euphorbia dentata Michx. Family: Euphorbiaceae More of the scientific description: Stems - From a taproot, multiple from the base, branching, erect to ascending, herbaceous, sparsely papillose-hispid and pubescent, to 60cm long(tall), terete, with milky sap. Some of the hairs are multicellular. (Most of this is Greek to me, as I haven't taken botany in over 30 years.) Leaves - Mostly opposite, petiolate. Petioles to +1.5cm long, pubescent as the stem, with a shallow adaxial groove. (Here's what I've been calling "berries.") A small cluster of minute glands is often present at the base of each petiole. The glands often brownish. Blades irregularly dentate to subentire, ovate to narrowly lanceolate, to +3cm broad, 8cm long, pubescent above and below, dull green above, bluish green below. Pressed leaves. (Not sure what this means.) Inflorescence - Terminal bracteate cluster of cymules. Pedicels to 1.5mm long, glabrous. Inflorescence. Flowers - Involucre (at anthesis) whitish-green, 3mm long, glabrous, 5-lobed, with a single cupulate nectary, (nectary green, to 1.2mm long). Lobes fimbriate and often with a pinkish tinge. Ovary green, glabrous, 1.2mm in diameter (at anthesis). Styles 3, white, glabrous, spreading, to 1mm long, divided nearly to the base and appearing as 6. Anthers bi-lobed, yellow, .5mm broad. Filaments white, glabrous, distinctly jointed in the apical 1/4. Stamens +/-30 per flower. Capsules 3-lobed, glabrous, 3-seeded. Flowers. Flowering - July - October. (Aha! That's probably why mine are still pods and haven't flowered yet. Maybe it will flower this fall.) Habitat - Prairies, glades, waste ground, disturbed sites, roadsides, railroads. Origin - Native to U.S. Other info. - This species is found throughout Missouri. The plant is fairly inconspicuous because of its indistinct flowers. It is closely related to the every popular Poinsettia that many people like to buy around the winter holidays. Be careful with the sap of this plant and most from this genus and it can be irritating to the skin and eyes. ---- So I still haven't figured out just how invasive it's likely to be, but I'm going to try it as a houseplant.

I have never heard of a common name for Colquhounia. I suppose "Himalayan Mint Shrub" is as good as any, though really it tells you nothing more than it's a shrub, it's in the mint family, and it comes from the Himalayas. Boring! If Dee or plantsplus don't manage to post a mystery flower in the next few days, I suggest someone else should have a go. It's an activity that seems to revive interest in this forum. I remember 2-3 years ago we had the same sort of thing quite regularly.

Thanks so much! This group always amazes me! I think it is definitely amaranthus (pig weed). http://articles.extension.org/pages/65208/weed-profile:-pigweeds-amaranthus-spp
