I am interested in the canary climber and black eyed susan vine. Look at the very short list of seeds I have. I have passiflora incarnata seeds. They are purple and white...the white ones are called "love in a mist" here. I have been cold stratifying them for 6 weeks now so they are ready to plant. let me know if you would like to trade. Here is a link that might be useful:

GG, How large do those vines grow for you? I grew morning glories last year and loved them but they were a little overwhelming. They would have covered the deck completely if I had let them.

I've grown several varieties of Thunbergia alata, including Salmon Shades and all looked pretty much the same except for the bloom color. The only real difference I noticed was that Raspberry Mousse, which I got as a plant, not started from seed, has never produced any seed pods. Can you post a pic of your vine?

I would look at the N-P-K numbers on the fertilizer package. N is the first of the 3 numbers, and if it's highest, that is most likely the issue. For future reference, unless you are growing in a pot with potting soil or a soil test has told you that you need fertilizer, for most plants it is as likely to cause problems as help because it may give you too much of something.
