Purple star with fibers

Post by rjlittlefield »

It was cold and rainy today, and I couldn't stand it -- I had to go find something to bring indoors and play with.

This reminds me a bit of a sea star, but of course it's actually a flower.

Anybody recognize what kind?

Clocks went forward today so 1 hour less sleep - that's my excuse :roll: .

My startpoint was "I don't recognise this flower!". So...

Well I've Googled endless March wildflowers of the Pacific Northwest looking for small, purple, 5-petaled flowers with white stamens and white, styleless stigma lobes (are those things stigma lobes? I did wonder if ithe flower was unisexual?). Then I thought "Could be an ornamental garden flower...or maybe unusual tree blossom...". ...all getting me nowhere fast :lol:

...and then I thought "Well it's sunny outside and Maggy needs her walk and there could be some photos to take....

So while I maybe know a little more about Washington State wildflowers I'm non the wiser as far as this particular flower is concerned.

Nice pic Rik.

Bruce :D

I'm clueless on IDing anything that doesn't have a pulse, but this is nicely done anyway. I assume it is stacked?

Deeply stacked.

It's not a wildflower. Actually it's ground cover under my hornbeam trees. Neither the hornbeams nor the ground cover is native.

And to tell the truth, I'm not sure I'd recognize this thing if I had a tray of options in front of me. :? The macro shot gives me a much different impression from the whole flower.

I'll let it sit a bit before showing you what I mean. :D

A very interesting flower Rik. I love the five sided shape. Could it be Periwinkle?

I too am at a loss for and ID, perhaps if we could see the whole flower :-k Lots of details in the center of that thing though, looks almost synthetic, the longer you look at it, the more you're attention is drawn into the center of the flower. Pretty neat shot Rik. :D

Yee-hah! :smt041 10 points and a tip of the hat to Doug Breda! :D

Funny thing is, I had to look it up to discover that you're right. We've always called them Vinca's. But there they are in Wikipedia and the UK Plant Identification site, not quite as big as life (and a whole lot less detailed :wink: ) -- Vinca minor, the Lesser Periwinkle.

Nice job, and thanks for the info!

Here's a closer crop of the same image.

I'm pretty weak on the anatomy of these things. Obviously the long clear fibers are coming from the sides of the tube formed by the petals. I presume that the cream-colored structures are part of the ovary, but what might be style, stigma, etc. is still a mystery to me.

Well, what happened was, you mentioned it was a ground cover and not natural, so I did a search for flowering ground cover and the Periwinkle came up with the same color and five sided flower design. Was only a guess without seeing the whole enchalada :smt028. The crop is excellent...Amazing the stuff that is right under our feet (you would not want to see a macro of my feet...or maybe :-k )

Could it be a passiflora?

Hah -- now that was an understatement! :D
