Wow, great growing Holly! I've never tried eating the tubers of OSP. Did they taste like regular potatoes? I have a
Ornamental Sweet Potato (Ipomoea batatas 'Tricolor') whose pot got dumped off the deck railing by squirrels last year and now the vine is trailing about in the flower bed. We've been so busy the past 7 to 8 months with getting one house ready to sell and then buying another that our yard and flower beds are mostly weeds. I've also been trying to stay out of the sun as much as possible the past year (due to a skin cancer on my nose) so the yard/garden has really suffered. Ornamental Sweet Potato Vines are so pretty and make great additions to combination pots.
