First Margined White I’ve ever seen in Seattle! Previous Seattle records were mentioned in a 1946 publication, but none for Seattle since then. And it visited the butterfly meadow I’ve been working on to create better butterfly habitat in for some years now! At first, I assumed it was going to be a cabbage white, which I actually don’t see very often in this opening in the woods, but with darkened veins and no dark wing tips, I think I indeed got a margined white here! I already have a lot of our native Tower Mustard - Turritis glabra (formerly Arabis glabra) growing here if it wants to come back to lay eggs.

The Tower Mustard is a species that I had found on a list of Seattle's lost native species 25 years ago, but then found one colony of the plant still in Seattle, and I established 2 new colonies here with seed from that first colony I found here, including this one in Lincoln Park.

Oriental Bittersweet naturalizing on private property north of the Sandy River, Rhododendron, OR.

Specimens were taken for submission to the Oregon State University herbarium. Specimens were confirmed as Celastrus orbiculatus by Aaron Liston and James Mickley.

This infestation had been actively managed by the property owner using manual methods for several years.

The patch was sprayed in in October 2023 using 0.5% imazapyr,

The character I found most useful was the ratio of the length to the maximum width for the medial pinnae—roughly 1:1 in P. lemmonii, 3:1 in P. lonchitis, and (though more variable) around 2:1 in P. kruckebergii. The two hybrids [31726, 31733] come in around 3:2.

I'd never noticed this wildflower before today, when botanist friends pointed them out, just a few growing by the sandy path along the sandy spit. Phacelia hastata is known as Narrow-sepalled Phacelia.

Earlier in the year, I noticed holes in the leaves of S. dulcamara but I never saw what created them. The holes reminded me of ones made by Black-margined Loosestrife Beetles (Galerucella calmariensis) on Purple Loosestrife (Lythrum salicaria). Today I found a G. calmariensis on a hole ridden S. dulcamara leaf.

I see rabbits eating blackberry canes in the winter. In the spring, I have seen them eating new blackberry leaves before the spines on the leaves develop. The new growth is a good source of dietary nitrogen.
