Ron, thanks you so much for this wonderfully detailed answer. I read it several times, it was so enjoyable, informative and well written. You really have a gift of words.

I'm going to ask the seller details about Clarke's. And post later.

It's a pity such an early flowering strain has been lost.

On an other note, Ron, have you written a book/ ebook on
convolvulaceae?

I'm glad you enjoyed my explanation and cautionary advisories...

You are going to ask the seller details about Clarkes ...HA (!)...They'll just google it and find my posts and whatever is in the PF's...they may or may not get lucky...

I'd google it myself , but I'd be 'afeared' of what I might find...

I didn't say Clarkes was lost , as in nobody has it , but it has been lost in the ghoulash of descriptions...I probably have some in one of the many little packets that I've traded for over the years , but which aren't always labeled correctly by the traders or by me by the time I get them ...so which one has the real Clarkes in it (?)...who knows...(!)

I haven't written any books (although I periodically get 'hounded' to do so)...

There's plenty of posts on the web...but , I too would still much rather read an' old fashioned book' (rather than burn my eyes and brain out looking into a computer screen) and mark the book up with all my underlining and brackets and footnotes / questions scribbled all over the pages...that's how you can tell that I have "really" read a book...

I will add that I most definitely do not think books are obsolete, because when (not if) they turn the electricity off = no electricity = no world-wide-web as we now know it (maybe people will find a way to link their minds together?!) , although generally only those with old fashioned books will have access to the written words of knowledge...everyone else will be in the dark...
People who have stored (in their minds) large amounts of useful or interesting information will once again become highly valued resources...

I couldn't do a book because I'm cursed with being a perfectionist and I'd never be able to get everything that I would want in it , at least not in any sort of 'timely' manner...it would be like Brahms 1st symphony (25 years) or Wagners entire Ring Cycle ( a virtual lifelong devotion) ...so gather whatever 'snippets' I post here'n' there...

There are a couple of groups mentioned on my homepage devoted to all Morning Glories and you or anyone else who is really interested is welcome to join in...smaller groups are generally best because larger groups aren't always well suited to the particular format of a site...

TTY,...

Ron

Ron you were absolutely right!

The vendor said that they were the same.
I actually did my googling at first and couldn't find much, besides one post by you, on Garden Web but not as precise as this one. I also missed the one on Dave's. (I found it after your post)

I know how is it with perfectionism, and while I love Brahm's 1st, (especially the Furtwängler version), each imperfect work, is perfect in it's own way, don't you think?

You can start with a small ebook, on the genus, the most common species, cultivars. Then recommendation about care, seed collection, fertilizations, indoor culture, common myths (invasiveness, poor soil, not flowering etc.), and finally recommendation of other species, cultivars etc.

What do think?

You mentioned;

"The vendor said that they were the same. "

They were the same in what way...e.g., Heavenly Blue and Clarkes or Ipomoea tricolor and Ipomoea purpurea ?

I appreciate your confidence in me but realistically a book thing is not going to happen, no matter what type of pep talk is delivered.

Try and utilize whatever material is posted...

Sorry for the confusion Ron. The vendor said, Clarke's Heavenly Blue and Heavenly Blue Ipomoea tricolor are the same. Meaning what they sell is the same as plain old heavenly blue.

I understand that there are probably many variations on the same theme, i.e. that the Heavenly Blue grown in Southern USA and the one in Quebec or Manitoba are not the same, due to ecogenetics.

At least that's what I understood through the long thread, Morning glory not blooming. Where you explained how can I produce a early flowering Morning glory, if I'm patient enough to let the first flower of HB to set to seed, over a period of years, in order to create one.

As for the book, when, if you're ready it's fine and if not it's fine.

Anyway, I've learned and still learning through all your posts. Last year you started me on humic acid :-)

Have a good Week-End.

I recognize 4 cultivars of Heavenly Blue as follows:

1) old heavenly Blue which flowers at about 90 days- likely from old wild Mexican stock

2) Clarkes early blooming Heavenly Blue which flowers in about 60 days

3) The newer (since about 1994) darker colored Heavenly Blue

4) The lighter colored Heavenly Blue - 1st isolated by a friend of mine in Texas and pictured in the database that you can't mention on here

So , all Heavenly Blue is Ipomoea tricolor , but not all Heavenly Blue is Clarkes early blooming Heavenly Blue and if the color is the newer darker colored , it is not Clarkes , as Clarkes was and still is a lighter colored blue , but not the very lightest.

Thanks Ron.

Very clear.

It's still a pity that Clarke's is "lost", especially for us northern gardeners.

Ron.. great explanation. But, how do they get seeds for Clarks and today's Heavenly Blue?? A cross? I want to try.. I only get seed pods that are sterile with Heavenly Blue. Thanks if you can answer.

Patricia, note the date of the post before yours. I haven't seen Ron on the forums for a very long time. A great pity, as his specialist knowledge was a boon.
