Heavenly Blue Morning Glory

The most popular variety and one of the loveliest with vivid, true blue flowers. The color of these flowers is breathtaking, even if you have grown them for many summers, they still impress year after year. The 4-inch blooms are borne on vines that will climb to a height of 12 feet. This strain was discovered by amateur seed savers named Clarke in the '20s and is dependably early and full flowering.

    Heavenly Blue Morning Glory

    Sprouted quickly, growing well. Another good Pinetree product.

    My blue heaven!

    Though I've grown several other colors I keep coming back to this gorgeous morning glory as my very favorite. With fond memories of seeing it climb upon some rusty wire fencing some 70 years ago in my grandfather's garden

    The best choice

    I've grown heavenly blue, and other colors especially the pink ones, Scarlet, and also grandpa Otts By far heavenly blue has the most blooms, and most importantly it hardly ever puts up volunteers and so it doesn't turn into a ****. The pink varieties put out so much seed that I'm still pulling it out a year later. In zone 8 if I plant morning glories in April they don't bloom until September because the nights become longer. i will plant them later this year-the blue is spectacular
