Just in case anyone had suddenly remembered. Please cam anyone identify
the Ipomea or Morning Glory that has HUGE pale/bright blue flowers? I
saw several plants last year one at Waterperry's even but no one could
tell me the name of that particular one.
The flowers are about twice to three times larger than the ordinary
Morning Glory and the blue is like a baby blue rather than the darker
shades.

Could it be Ipomoea indica? Try the following link for pictures - the flowers
look very large.

Nope. They are almost always dark blue, and little larger than a
common morning glory.

Ipomoea indica (formerly I. learii) flowers open an intense blue
taking on purplish tones after a few hours before becoming pinkish as
they fade. It's a perennial species with 10cms. wide flowers that
does not seem to set seed in this country at least and has to be
propagated by cuttings. I grow it outside, where it runs about for
7m. or more each year. I've noticed that under glass in more equable
temperatures, the blue coloration remains purer for longer with fewer
pinkish-purple tones. It would seem that the intensity of the blue is
temperature-dependent - the last flowers opening in December are
always pink with only the slightest hint of blue.

As to the plants Janet saw at Waterperrys, it's a fair bet they were
Japanese bred, Ipomoea nil variants. For many years, the Japanese
have been working on a very wide range of colour forms and flower
sizes with some producing flowers that expand to rather more than
15cms. across. The problem with these more spectacular forms is that
they really need to be grown under glass in this country if the
maximum flower sizes and best colours are to be achieved. In a mainly
hot summers like last year they do well, but in cool or wet summers
their performance compared to 'Heavenly Blue' is often very poor.
Which is why they are not more widely seen in the UK.

Some friends who live in Florida usually grow a few from seed that
they get direct from Japan. I've seen photos of them in the past and
some of the flowers are almost too large. I've been trying to get in
touch with them, but they seem to be away at the moment. I'll try and
get a source address for you if you like,

Probably only at low temperatures, then. I have noticed no colour changes
from temperatures of 10 to 30 Celcius in my conservatory. And it grows
a lot more than 7 metres in a season even in a UK glasshouse! In that
range, it always opens an intense, fairly deep blue in the early morning,
becomes pinkish and starts to flop in the evening, and drops in a fully
pink, shrivelled form the next evening.

Searching the Web indicates that it is globally self-sterile, because
its pollen is non-viable (I can't remember if it doesn't germinate, or
germinates and fails to reach the ovary). Apparently two other species
of Ipomoea (at least) will germinate pollen on its flowers, but they
then fail to grow down the tube to the ovary.

And it propagates even more easily by layering - just try to stop it!

Nick Maclaren.

I thought it might be but Nickys seeds site and two catalogues seem to
suggest that this has a darker blue flower with a white centre and the
ones I saw last year were HUGE flowers and a baby blue definitely.

Yes! that's exactly the colour John, though difficult to judge the
size. I'll try and get the seeds from that one as it looks the nearest!
I did grow several varieties from the Chiltern seed catalogues last year
but chose Milky Way which was a white striped one, a crimson one, I
think was Serenade and one that never did anything.
A big mistake as everyone that came to the house remarked that I had got
a wed growing amongst the climber next to the front door They all
thought it was bindweed
One person actually had some in her hand having helpfully yanked a
string out whilst waiting for me to answer the door!

Nick, that isn't what is in the photograph link. That link shows exactly
the baby blue colour that I saw last year.
I was surprised because several of the people growing it are not
'specialist' gardeners in any sense and had just apparently "sown a
packet of seeds"

Thank you, much appreciated. Waterperry's had theirs growing outside the
restaurant and the two gardeners I asked did 'n't seem o think it was
anyhting out of then ordinary.
One friend had grown it in her garden in Swallowfield, again though a
little protected on her south facing wall, it apparently had come from
'just a packet of morning glory seeds'.

Two others I saw in NGS gardens and again the owners had thought it
nothing strange.

It is the blue in the link that John gave for indica but, as you say, it
might be the growing conditions?

It was very attractive and I would love to have that colour!

Ah well at least one of the plants I saw last year had seeds.
I did get three seeds from an early set pod (with permission) but they
didn't germinate. Waterperry's was too near the restaurant door to even
think of taking a pod
Not that I would of course, without first asking!

I think that you will find that it is NOT I. indica. In fact, I am
surprised at that Web page, because at least most forms are much darker,
I didn't know that there was a white form, and the leaves look wrong.
When I referred to a Web search, I was using the more botanical hits
as authoritative, incidentally. See the following for a more typical
set of flowers and leaves:

http://forums.gardenweb.com/forums/l...5728110.html?3

I have also never discovered whether the darker one that was/is common
in Turkey and was grown by my great aunt is I. indica or something else.

My guess is that what is on that Web page and what you are referring
to is a different plant. Now, whether what I know as I. indica is
the true I. indica, or whether what that page and/or you do is, I
am less certain. I should have to find a genuinely authoritative
reference in Ipomoea to be sure. And, of course, the botanists may
well be playing name games again :-(

It's a very bad and misleading web page. You have to look further to
see that all but one of the pics that are accredited with being
Ipomoea indica are entirely different species.

Ah. Now that pic in the 3rd message down is more like it - as typical
of I. indica as you could wish. It is the plant that I grow here and
grew many years ago at my nursery. My first plant was from a cutting
I got from Oxford Botanical Gardens, but in those days we all called
it Ipomoea learii.

Janet, if the plant you have seen was grown from seed, it could not
have been Ipomoea indica. That species has confounded botanists and
horticulturalists alike because it has never been know to set seed and
its sole method of procreation is via self-layering. Can you remember
roughly how big the flowers were? From the Ipomoea perspective, large
is in the region of 10cms.(3") or more across (I. indica produces
flowers this size). Very large flowers exceed that by a fair degree
and if they are closer to 15cms. (6") or more across, they almost
certainly must be variants of Ipomoea nil.

I am glad that I have not lost ALL of my marbles - that's what I
thought!

I have never seen them that size in the UK, but I am no great expert
on them. The seeds that I have sown that claimed to grow to that
size, er, didn't.
