I have these in a large pot and they've done extremely well up until now. I'm not sure if it's from the changin of the seasons or if it's a disease of some sort. Any help is appreciated.
Oh, and how can I get seeds, I think I found them but not sure when to collect them.

It looks like a Vinca (major or minor, not sure); and a nice one at that. It's definitely not a Plumeria.
Vinca's are really an outdoor plant which prefer full to partial sun and need to be trimmed back through the winter months to rebloom in spring.
Although you may have brought it inside for the winter...?
Nevertheless, it should probably be cut back so it will resume new growth come spring. I'm in Southern California and that is what I did with mine which is in a pot on my patio. Plus, I repositioned it on the patio so it gets alot of direct sun throughout the day.

Often mistakenly called Vinca Major, though it isn't
Is a member of the Catharanthus Species
Is a wonderful ornamental annual, though I would personally consider itt more od=f a tender perennial. It will grow and bloom until frosted out.
the black sposts are a fungal infection that is pretty much harmless if unattractive. treat like Rose Black spot. remove the infected leaves, wash your hands before handling the 'clean' foliage.
Spray plant , including undersides of leaves with a solution of baking soda and water. one tablespoon to a quart of water with a few drops of soap to help it spread. If you want to add a pest repellant quality, a tablespoon or two of habenero sauce ( the watery type, not the chunky kind) to the solution.
Biottom water to prevent wetting of the foliage.
That shoud fix it. Umm you will have to reapply the solution about once a week to prevent infection of the new growth.
Next patient please.

Just keep it happy, plenty of light, water when the pot seems light for its size, apply antifungals to keep new growth from contracting that blackspot and that pretty little Periwinkle should snap right back.
Oh and it won't hurt ti cut it back to about half size. This will reduce stress on root system and encourage new growth. Might seem harsh, but it works.
