Most usually, lunaria is a biennial - flowering the second year and dying. It will set seed and continue the cycle but you will need to sow this annually for the first 2 years until a continuous supply is established. However, there is a perennial one - lunaria rediviva and a hybrid, 'Corfu Blue' which is sold as perennial (mine is in its second year - first year of blooming - so we will see if it returns next year)

By "Black Eyed Susan vine", I'm guessing you mean the annual Thunbergia alata. If the pods are fully developed (and not immature), you can leave them to dry out and plant next spring (or indoors a few weeks before the last frost). Once dry, they'll keep better under refrigeration. Lobelia can self-seed and you may well get plantlets next spring by sprinkling seed on the ground now. However, I think it's too late in the year to expect cuttings placed in the ground to take root and overwinter.

woebegonia, it's good to know for the future that they can self-pollinate, i'll make a note. if i am not mistaken this is a large-leafed tuberous? if you pinch the top tip and add an inch of fresh soil into the pot too - it'll trigger good basal growth. then you can remove new basal stems when they are 4-5" tall (do not cut, just snap them off at the base) - they would make quite nice new plants. but you'll need to grow them thru the winter with good light. they'll bloom in spring if you have good culture without going into dormancy. or so i read, i have not actually done so myself. however i did induce the basal growth on my plant- 5 big shoots in addition to 2 canes. and i can see already some buds forming on young shoots too. though mine drops most of the buds - too hot here. but i want to grow it large to increase the tuber for next year. new basal shoots will make it very bushy. you flowers look very nice, i wish mine were better...

It takes a number of years until the vine is mature enough to bloom....sounds like this is coincidence
