Opposable thumb sepals on this Chinese Ipomoea nil

I do not remember how I obtained seeds of this morning glory, but the seed packet was identified as Chinese Morning Glory. I grew it out over the previous winter and enjoyed its striking blue flowers and interesting sepals. The species turns out to be Ipomoea nil. Note the arrangement of the blade-like sepals, almost appearing to have opposable thumb.
