Did you dig those up? Mine had decent-sized tubers last year (their first), and this year they're huge!! I'll try to get some pictures tomorrow. I have some pulled already that sprouted late this year (really small but I'm hoping they're white), and several two year old tubers that are maybe 7 pounds each! I don't have a scale, so that's just a guess...but they're definitely heavy!
Holy moly -- 7-lb tubers??!
I have to admit... I just pulled them out of the pots and threw them on the compost pile
I'll try pulling one of the root balls apart tomorrow to see what is actually there, but it definitely can't be anything very large. I had the pots inside my (unheated) hoop house; I think next year I'll try planting the 4 o'clocks directly in the ground in there.
David -- I'm afraid I didn't keep track of when they started blooming, but our first freeze this year was mid-October, which is pretty typical; and I never put anything tender out before June 1st (and even that can be pushing my luck). Oddly, I can't find any notes as to when I started the seeds of the 4 o'clocks... but probably around the beginning of May? Mostly I was just/ really happy that they grew at all this year, I don't have a very good record of getting 4 o'clocks to sprout!
