According to the old books, blue flowered Ipomoea tricolor were in cultivation over
a century ago, but those plants were
very late blooming. This was sometimes the case with plants little improved
over their wild forms. The Cosmos
bipinnatus grown in the late nineteenth century were huge, coarse plants,
tall and very late blooming. It was not until well into the twentieth century
that dwarf, early-blooming forms were developed.
‘Heavenly Blue’ came into commerce as “Clark’s Early Heavenly Blue Morning Glory”.
Anne Roe Robbins, in her 1949 HOW TO GROW ANNUALS points out that it
was introduced before there were All American Selections awards – the point
being that one would expect the best blue flowered plant we can grow easily in
our gardens to have an AAS award. Her
book has been reprinted by Dover; be sure to at least see the original because
the Dover reprint contains revised cultivar lists.
On the street where I grew up in Silver Spring, Maryland in
the 1950s we had a neighbor whose garage in many years had a glorious swag of
this morning glory over the doors of the garage. I’ll bet garages all over America have been
festooned similarly, even to this day. Garages, out buildings, fences, the
otherwise bare, sunny façade of a building – all are ideal places for this
plant. It pays to give it plenty of room: a sunny surface of several square yards is
about right. When you come out in the morning and see a mass the size of a bed
sheet of the intensely blue flowers you won’t regret being generous with space.

When I lived in Frederick, MD, someone had run twine up to the top of their flag pole and they'd plant blue morning glories at the bottom that climbed up and made a tree. It was a sight to see! For a garage though, I think I'd rather have smilax...
Leah, have you seen the posts on Smilax yet? If not, use the search function at the upper right part of the page.
