I bought a handful of about 18” stalks 12 days ago and put them in water. The ones in my aquarium, in front of the south window, have over a foot of new growth. Actually, make that the one in the aquarium, as the other one went in the ground an hour ago. Haven’t tried seeds, but rooting stalks in water seems to work pretty well.
That’s good to know. There’s an upscale grocery store not far from where hubby works. I’ll have him look for some of the stalks along with some gourmet sweet potatoes. We’re going to try growing our own sweet taters this year.
