Here's the first major update to the Morning Glory Homepage in 5 years:
Summer Skies morning glories grown here in the yard!  They were
unbelievably healthy.  The source of seeds is unknown, a friend got
them on Ebay in 2002 listed just as pale blue morning glories, and she
has forgotten who the seller was. I had two plants growing as a mass on
5 bamboo sticks, having around 100 flowers each morning as of last
September.
