Long Time Oregonian & first time visitor to Rowena Ridge on Friday May 3rd. Quite windy but enjoyed the view, the rippling grasses, the daisies....

They're lovely, but they are not daisies. :) pnwflowers.com/flower/balsamorhiza-sagittata

I was distinctly told by "flower people" that the blooms on the Memaloose hills were arrowleaf balsamroot. Are both varieties in The Gorge? Is this another case were the common name is insufficiently precise? (I can never remember the Latin name by the time I'm home.)

Attempting to educate myself comparing pnwflowers.com/flower/balsamorhiza-careyana it appears that both do appear in The Gorge but that sagittata occurs further west, in Multnomah co. Also pnwflowers.com specifically shows Balsamorhiza sagittata (Arrow-leaf Balsamroot) at the Tom McCall Nature Preserve:

So I'm totally confused now. Are there two separate seasons or something? Has one variety replaced the other?

Thanks to all for the corrections on the flowers. I was repeating what a long time hiker in this area called them. :oops:

Alright then, you can name this person for appropriate shaming. :roll:

B. sagittata is a hundred miles farther east or south. Here's the map from the Oregon Flora Project Atlas, with sagittata in red and careyana in yellow. (The Rowena dot is green because I had selected it, and it's careyana). The two species are hard to tell apart, and there has been some confusion over the years. Apparently the confusion affected pnwflowers.com. Some Gorge specimens show some hybridization between careyana and deltoidea, but NOT sagittata. deltoidea is the Puget-Willamette valley species.

I've gotten the impression that B. careyana is a relatively recent addition to the inventory... Maybe the same flowers would have been considered sagittata in the past.

[Edit: no, it's not recent at all; it was first described and named in 1849. So I have no idea why it's so frequently mislabeled.]

From the Burke Museum's page: "The several small heads help separate B. careyana from B. sagitatta; also, the leaves on B. careyana feel like sandpaper, while the leaves on B. sagitata are soft and silky. However, the two species hybridize, and numerous intermediate forms are found."

Nawww.

I'll just quote a former president: "I accept responsibility--but not the blame".
