Pam, have you tried "early call"? I grew it this summer in Spokane. It is
true that it didn't start to bloom until late August, but we didn't have
killing frost until late October this year, so I was able to have flowers
for that long anyway. In theory, it is supposed to be the quickest variety
of morning glories to come into flower, although not the most spectacular,
and thus recommended for short and/or cool summer climates. I agree with you
that the annual varieties of morning glory would never be invasive in cold
northern climates. I do remember in north Florida that the little square
orange-flowered morning glory was, shall we say, rather generous in its
self-sowing habits. And there is also a purple-flowered perennial morning
glory there that has a bad reputation for taking over large swaths of
ground.

Ipomoea ( Mornig Glory). I am dealing with the pests in the back yard
and I
dont want to introduce them to the front and regret it. So, whats your
experience with Ipomoea?? What kind are least invasive? What kind are
most?
ANy and all input would be great!

MICK!


My experience in zone 8, planting the seeds in a sunny location, is they
do poor to mediocre, & do not come back a second year. But then I put
them
in a semi-low-maintenance location -- they might've been fine annuals in
a
moister spot.

I don't believe we get enough summer heat to successfully grow Ipomoea in
the PNW. I have had success with Spanish Flag (Ipomoea or Mina lobata)
grown
in container from starts, but seeds just don't do well. Even a start of I.
coccinea in full sun fizzled out.

These are all annual vines in most of the country and relatively easy to
start from seed in climates with hot summers. As annuals they should not
pose ANY invasive threat and in a large portion of the country, even the
seeds will not ripen sufficiently to be a problem. Just stay away from the
bindweed ( I doubt you will find this available for sale, anyway.) The
tricolor cultivars are probably the most popular - 'Royal Ensign',
'Heavenly
Blue', 'Pearly Gates', 'Flying Saucers', etc.

Water spinach, Ipomoea aquatica, IS an invasive but I doubt that is the
type
of morning glory you are looking for.
