No 1 looks like Plumbago auriculata (P capensis) No 2 - Chlorophytum comosum - "Spider Plant" No 4 - possibly Duranta the others I will pass on

#1 - definitely an artemisia. Probably mugwort but it's hard to say for sure with the young leaves. The mature leaves have a different look and in short order, you'll know for sure. #2 - Besides the weeds, I see both catnip and lemon balm. #3 - Agreed, some geum. #4 - Definitely feverfew.

Common name for the plant is drunkard's dream. It's very easy to root. Just take a 3" piece of the plant and stick the cutting in a pot of soil, after it's had a chance to dry for a couple of days. Mike

That Viburnum has a big, broad prominently veined leaf, like that of V. davidii (but appearing broader relative to its length.) In fact, it is sometimes sold as that species by mistake. V. cylindricum also produces large leaves, although more flat, flabby and tie-like, without its venation being such a feature. Plants seen here have also tended to produce leaves with a grayish cast, although this appears to be variable. It is on the tender side, I grew it about yard high before it froze out on Camano Island. There was a large, persisting one in a Bellevue garden that is probably still present. Although seen as a low mound when present in local outlets, V. propinquum has been known to make tall plants on the University of Washington campus. The Lynwood Fred Meyer also has an eye-level planting of V. davidii; it grew nearly as tall or nearly so at my house near Seattle some years ago. I took this planting out, as it had become too much for a narrowish foundation bed. V. cinnamomifolium soon forms a pointed top and grows tall, rather than mounding up over a long period of time. One here on Camano is already becoming pointed after only a few years (and at less than a few feet in height).
