Happened to drop by this site while searching for a name of a particular flower. So glad I landed here. Its a beautiful site with lovely pictures and great information. I have a few of these vines in my garden, very fond of them.
I am rather proud of this vine, as I renovated it from some pitiful sticks in the planter in front of my porch. I ran rope up & down to form triangles against the west-facing wall perpendicular to the porch & have been training (& judiciously pruning) Clerodendrum thomsoniae 'delectum' along it.
Thanks to all of you! Yes, it does bloom all the time. When I posted the picture, I read back through the thread & saw that Casimira had also posted a lovely pic & the information that the hummingbirds love the flowers. True!
There is one of these next door as well, & it's completely out of control. Once established, they grow very well here, but the vines next door are like Sleeping Beauty's castle. They completely block the light from the front of that house & overhang the sidewalk so much that no one can walk there. I've seen them growing in that state a great deal, which is why it took me a long while to warm to them. Mine are kept so that they provide some cool green relief to the white wall & so that the floral displays are highlighted.
I've wanted one of these vines for umpteen years & was quite jealous of Casimira having it. So back in August, when I saw it in front of my favorite plant vendor's place, I did a Three Stooges halt/double take there on the sidewalk. It's called "patito" here -- ducky. I like "dutchman's pipe" better.
Actually, the blooms are bigger than they appear in that last picture. The leaves vary a good bit in size. It's a rampant grower. I suspended a "ladder" I made from twine & dowels from a horizontal bar that supports the covered part of the driveway. The bar is @7' high, but the tendrils have overtaken it & are colonizing the carport roof and the property walls.
One of the things I read about the vine is that the flowers have an unpleasant odor, although the ones on my vine seem to have none at all. Have you noticed any such thing, Casimira?
The one I have has no odor whatsoever. My friend who I walk my dog with in the a.m. is familiar with some of the other species of them. I will ask her if she knows of this.
The large elm tree that we had to have taken out this past summer was the main support of the original vine that I planted several years ago. When they took it down, the seeds from the pods (each pod holds about 30 seeds) were dispersed all over. I have sproutings of them everywhere!
There was discussion about the size of flowers & leaves on the dutchman's pipe vine. I finally got around to taking pics to show the sizes. The flower one is bad because it was growing close to the street wall & I couldn't get far enough back to focus correctly. Also, had to hold the tape measure in my left hand & it was too awkward to hold it right-side up. Take what you can get.
Yes, found it back in 2009 although no picture there now. From what you say, it seems ideally suited to the UK climate.
Also there is mention of a blue Thunbergia but again no picture. I love Thunbergias but generally there is only one variety available here. Any chance of a picture anybody?
Bixa would be the one to find a blue Thunbergia and photos of as I saw a gazillion of them when I visited Oaxaca years ago.
They are truly gorgeous.
Researching Thunbergias, the blues in particular,it appears there area slew of different species of them much like the Clerondendrum family. And, I am loathe to cite one without knowing specifically the botanical name as opposed to the generic common name. They all have different characteristics(Pet peeve of mine, sorry...).
I planted mine later than usual (late January, early February I wanna say?).
Anyway, they came up nicely but I have been disappointed in that they are/did not bloom as profusely compared to previous years. And, I do pick them almost daily to prolong their flowering.
I attribute this to the PH of the soil being too acidic and too much nitrogen. Sweet peas perform much, much better when one adds some lime into the soil. They like a "sweet" soil.
I learned this from one of my elderly clients from back in the early '90's and she was right. I regret not adding the lime this year and now know it is proof positive that her sage advice was/is "spot on".
