Thanks, tyrlych... I had thought that based on the "It had yellow flowers in summer" post nearby, but the branching habit and the fact that this is its first year and it's blooming its head off have baffled me, neither trait seems to be "normal" for O. biennis from what I'm reading. Otherwise, it looks just like it... :-)

F. elastica for the 2nd, rubber tree plant.

First one is Syngonium podophyllum, AKA 'Arrowhead Vine.' Not a succulent like the second, but a tropical plant (grown as a houseplant by many, some grow outside year-round if it's warm enough. Not frost tolerant or cold tolerant for that matter). Planto

Well thank you all! I was tempted to leave the "weed" since it takes up a complete bed but perhaps I'll just deal with having a bed of dirt instead. Buckets - thanks for that post. The foliage looks similar but not so sure about the flower. Right now I have droopy stalks with teeny tiny pink/white buds (?) on them. They look more like seeds. It amazes me that I have so much of this and never had it before. AND it's only in one bed - where I direct sowed seeds (from a trade). That'll teach me, won't it? Guess I'll be yanking this week! Maybe I'll move some of the malva to the new barren spots...
