Yes, great dark purple/green leaves 👍 & not touched by slugs & snails, which is definitely not the case with the other runner beans! I've found cardinal climbers difficult, but got 2 cobaea growing on an arch, but never heard of love in a puff! @ublaszko
I heard about love in a puff vine from Rachel and she sent me some seeds earlier this year. I bought cobea seeds in Poland and managed to get it to germinate but it was April when I got them so nit enough time to get the flowers. I'll try again next year.
Yes, I've found that cobeas need a long season if they're to flower. Mine ha ent yet & it was late last summer/autumn when they did & after 2 months of hot weather too! @ublaszko If this hyacinth bean produces seeds I'll save you some if you want? 👍
