This is a direct followup to my previous nighttime flower photography post with proper natural lighting and more effort at positive ID for these flowers, plus a bonus plant I wasn't able to photograph the other night. These aren't all of the exact same specimens, but I hope they suffice anyway. I used the reference photos at http://www.pnwflowers.com to help.
The first plant I had previously identified as mock orange, a.k.a. syringa, a.k.a. philadelphus lewisii. Something about that never quite satisfied me, though. I didn't detect the characteristic scent, and neither the flowers nor their clusters seemed right. The leaves were wrong, too. It grows in the area, but this ain't it. @scribblingramma said she thought it might be serviceberry at first, but also correctly ruled that out.
Now I think it is pacific ninebark, physocarpus capitatus. Note the leaves and the ball-like clusters of white flowers with five petals and prominent stamens. I was intrigued by the contrast between this particular shrubbery (Ni!) and the dead branches it was growing through,
The next photo I had identified as a mariposa lily, but which variety? The only one that site lists in the Spokane area is calochortus macrocarpus, the green-banded mariposa lily, but this is very much white, not purple. Perhaps the site is wrong, or perhaps this is still misidentified. Whether the map agrees or not, the small purple spot at the base of the petal suggests calochortus subalpinus, the subalpine mariposa lily
Of less dispute is the wild rose, rosa piscocarpa. The map says it isn't here, but here it is. On the left is another photo from yesterday evening. On the right is from a few days ago when I saw one in a vacant lot in town just starting to bloom.
Yup. That's a honeysuckle. Lonicera ciliosa. At least this is hard to misidentify, and the map says it's in the area.
The above flowers are native to the northwest, but this last one is not. These purple flowers are some type of vetch, probably woolly vetch, vicia villosa I found it along the road right where the description said it tends to thrive. There was just enough of a breeze to make photography a bit of a challenge.
All photos taken with my less-than-spectacular smartphone and cropped or resized before posting here.
