I just learned that we can overwinter the corms of sweet potato vine!  The underground bulbs are much like sweet potatoes;  they just dont taste as sweet.  Sweet potatoes are way too much work to grow in the garden, but the ornamental sweet potato vines are so much fun to grow.  They are great in hanging baskets, or as fillers in planters.  And they come in several colors.  We love them.

 

Well... we don't have to buy new ones every year!   They are not perennial, but you can dig them up and save the "potatoes" by keeping them cool and dry.  I'm going to try it this winter by cutting off the green part and putting the potatoes in brown paper bags, and keeping them in the basement. 

 

I'll let you know if it's worth the trouble.

 

HAPPY GARDENING!!
