Diplandia vine

I spent most of my lunch hour at the local nursery. They had this beautiful vine, call a Diplandia vine. It has huge yellow mandevilla like flowers. I haven't been able to find anything else about it on the web. Has anyone heard of it??

Seems like Dipladenia is a synonym for mandevilla. I'm sure someone who knows more about this stuff will correct me.

Anyway - http://plantsdatabase.com/go/1711/ ?

I found a reference to Diplandia which also pointed to mandevillas, but to Mandevilla sanderei.

Here's a page that talks about a yellow http://www.garden-services.com/mandevilla.htm at the bottom of the page.

The vine in question is a Mandevilla, apparently, just don't know which kind. Someone will.

Thank you. I did a search, but I guess I had the spelling wrong. I will have to look into this further. I really liked the plants they had. They were all over 6' tall (and expensive), but if I could find a smaller one, maybe I could afford it!!

Mandevilla splendens is yellow. It has shiny leaves and medium sized yellow blooms.

See, I knew someone would know. =)

By coincidence, Ulrich and I are having some correspondence about Mandevilla/Dipladenia, so here's my two cents' worth (and it's worth about that much, give or take a penny :) Dipladenia is the outdated name, according to most sources, even though some plants are still sold by that name.

Hortus - although outdated - is still fairly authoritative and states that M. splendens has pink flowers, although Baa recently noted that some Mandevilla splendens have yellow flowers: http://davesgarden.com/t/376420/, as does the closely related Urechites lutea.

M. boliviensis (which some sources list as a synonym for M. splendens) has white flowers, as does M. laxa.

M. sanderi (also sometimes listed as a synonym for M. splendens) has pink flowers, although new cultivars include deeper pinks and reds.

I wish they would quit changing the names. I ordered M.boliviensis(thinking it would be M. laxa) and it was what we call Diplandenia and not the M. laxa that I was looking for. I now have M. laxa, it is fragrant and the one I wanted. I have to remember that M. Red Riding Hood is what we called diplandenia, and M. Alice DuPont is the pink vining one when I'm trying to order stuff. I noticed a white with yellow(that's how it's listed) called Sun Parasol, no species name given. Wonder what it looks like?

I just looked in my catalog from where I order cuttings, they have Mandevilla Yellow(Urechites lutea) listed, but another company has it listed as M. splendens. Wonder if they are selling the same plant?

I really think the nurseries and wholesalers should get more staff that can identify plants properly. There is a big problem with misidentified plants which is a huge headache when your a collector and/or a PDB editor *G*
Rant over.

Terry is right Diplandia is an outdated name and M. splendens and Urchites lutea are so closely related it's hard to tell the one from the other ... awaiting more name changes in Mandevilla.

Baa, I totally agree! I deal with some wholesalers and I feel like saying "send me samples cause I know you've got it tagged wrong". One even had yellow allamanda tagged as yellow mandevilla, geez! Some wholesalers are worse offenders than others though. I have finally found one grower that is really good about having the correct id on plants, he just doesn't have a large variety yet.
