Answer: Cobaea scandens, the 'Cup and Saucer Vine', is a half-hardy perennial that's usually grown as an annual. It's native to Mexico. You were wise to start the seeds indoors and then transplant outside when the weather warmed. If you keep it in a warm and very sunny area, it will bloom about mid-summer. I think you had success this year because the weather was warmer than usual. In years when summer is cool, the plant won't bloom. But it's a vigorous climber, so it's an interesting garden plant. I think I'd take a chance and plant it again next year - just in case!
