Any Expert On Flowers Out There?

Hypericum (St. John's Wort). There are many species of hypericum and this one looks like Hidcote but I could be wrong.

Wow, that was fast! A million thanks, Kathleen!

Kind regards.

It might be a variety of St John's Wort. Nice photo!

Oops! Kathleen beat me!

Its not st johns wort - it has longer thinner petals

There are many varieties of St John's Wort, some with shorter stamens. The foliage and buds look like it, too.

Pablo, on second thought, your flower looks more like Hypericum patulum.

Thanks, Julia!

Heather, I was looking on Google Images and found the flower on your link. Could it be this variety (Hypericum Patulum)? Looks more similar.

Kathleen, you were faster than me :) Thanks a lot, everyone! I think Kathleen is right.

Guess so... if you took it in spain you could look up varieties there.

Hypericum Patulum is the latin name for a variety of St John's Wort, so everybody is right!

Heather, I took it in Viena, Austria, while I was on holidays there last summer. I thought I'd say where I took it in case it made it easier to identify.

I think it's also called Rose of Sharon.

St. John’s wort, shrubby -- perhaps ‘Sunburst’ (Hypericum frondosum ‘Sunburst’)
it's a shrubby vine or a viney shrub.
here's a macro shot of a blossom from my front yard. It grows about 2-3 feet tall, likes lots of sun, and can get by in heavy red clay soil with little or no watering once established( in Atlanta GA.
)

It's as Gregory said - St. John's Wort - hybrid "Sunburst"

Thanks everyone!

Gregory, I love macros and that's an awesome one!!

Roy, when I first read this question I thought it was Hibbertia scandens but decided the centre was a little different! Maybe it depends how long the flower has been in bloom?

Margaret, I think you may be correct - hmmmmm - I'll have to do a bit more research.

Me thinks Gregory is correct - oh well - never saw a St. John's Wort with that large a flower before.

I'd say it's St. John's Wort. We have this stuff growing all around our house. It spreads a lot and takes over and it's hard as hell to get rid of. You have to dig it out by its extensive roots and even then, it manages to come back somehow. I tried to dig a bed for tulips and daffodils and it worked for a year or two but the St. John's Wort took over again.

I have a species of ground cover (Hypericum calycinum) and vinca duking it out on a dry, shady hillside behind the house. I think the vinca is winning. I hate vinca with a passion because it's impossible to eradicate but the blossoms are a pretty shade of blue and they survive in the driest of shady places.

I also have the old-fashioned shrub variety of St. John's Wort (Hypericum Hidcote) that's the same variety that my grandmother grew on the coast. It reminds me of happy days and good people. They like sun and will survive with very little water. Also grow the variegated groundcover (hypericum x moserianum 'Tricolor') and it's really pretty even when it's not in bloom and it's not a rampant spreader.

I have two versions of this in my garden, one with large flowers the other small. They are both hypericum.

There is also a noxious species, Klamath weed (Hypericum perforatum L.), that's spread throughout the watershed here and I'm constantly ripping it out. If they ingest enough of it, it causes phototoxicity in livestock.
