Gardeners' Notes:


On Sep 12, 2018, yrrej from El Paso, TX wrote:

Here in El Paso Texas this plant requires full sun and water. It starts rather slowly in the spring and summer then grows explosively towards the end of summer. Will completely smother other plants given the opportunity. Roots here may survive the winter making this a perennial vine given adequate water. Foliage dies in the winter so it leaves messy dead vines all over everything which have to be removed. Can't really recommend it given all the other vines available except for coverage in a trouble area.

I thought I had a green thumb until I tried to grow Heavenly Blue morning glories. This year is my 4th (and last) try at it.
I nick the end opposite the "eye", then soak in warm water until they swell and start to germinate, then I plant 1/4-1/2 inch deep, in full sun to partial shade, and provide them with large chicken wire and wood pole trellises. I do not fertilize them, having read this is a bad idea and that they like the sandy soil in our area. I planted them on 2/19 this year.
This year I tried 3 locations, hoping at least one would work out. I have them planted on trellises near an east facing fence, a north facing fence and a south facing fence, and 2 of those locations are at the back of beds full of successful plantings. ... read more

Its on my fences( i live on 5 acres)ran under my deck to the other side of the house. Through the garden. BUT.. Its worth it. Those BIG blue flowers are so intense. I actually have small airplanes from the local airport doing circles around my property. I can only imagine what it must look like from the air. Not to mention that the hummers love the flowers to. I live in the Tampa area and it does exceptionally well here. It has come back every year, the heat, the draught, the cold has not killed it. Although it would be nice if it would slow down a little!

4-4-2010 I planted seeds of Morning Glory, Grannyvine Ipomoea tricolor 'Heavely Blue'. After soaking seeds for 24 hours in warm water, I planted them in a 4" by 20" pot. I've placed a thin lattice for my vine to run up. I may use fishing wire to start the young vine towards the lattice.
I really appreciate all the good information you folks gave on Dave's Garden!
I previously grew the old Ipomea blue that was too aggresive. It was a hand-me-down from Grandmother. It had undergound roots, ran under the house & up through the deck floor.

How could you NOT love this beauty? It is one of my favorites and this year it will be paired with Candy Pink! I can only imagine the offspring of those two! :-) My first experience with HB was in 1978 in Illinois- My mom had a mass of them growing on a trellis next to the porch. I fell in love with them at the age of 12! The next time we grew them was in 1980 in Georgia. My Mom ammended the Georgia clay and we got them to grow up the wrought iron fence at the patio. If you have room for these, you should grow them, as you won't be disappointed!

These plants are neat in Pennsylvania because they bloom in the fall time when most other plants are done blooming. They grow wild here too so it provides color on the roadsides everywhere, especially next to farming fields. I have one growing in a pot on my balcony. I guess they can be an invasive vine to a nice flower bed. Mine is on a shelf where it is free to climb wherever it wants.


On Mar 14, 2008, rebecca101 from Madison, WI (Zone 5a) wrote:

This did not look as nice as I had expected. It is an absolutely monstrous vine - 3 or 4 plants took over about 25' feet of fence and sprawled on the ground nearby as well, smothering everything in their path. It was mostly foliage with somewhat sparse bloom - maybe my soil is too rich for it. It did not bloom for me until fall, and was killed by frost so bloom period was very short. The blue color of the flowers was pretty, but I do not think I would plant it again.


On Sep 8, 2007, woofie from Chewelah, WA (Zone 5a) wrote:

I'd just like to add that I've had no trouble with transplanting the vines. I started them in my greenhouse in pony packs and every one that sprouted (nearly all) survived being transplanted outdoors with no difficulty. And even the ones that didn't get moved into larger pots (I started WAY too many) keep hanging in there and have produced a few blooms in those tiny little pots. Very easy to grow and just beautiful.

This is a great flower--I absolutely adored having it in a large pot with a trellis last summer. I also had some basil growing in the pot as well--this helped hide the bare stems as the morning glories got older. This year I'm trying them in a bed with a large trellis and they are doing very nicely. I would say one thing--while it is true these plants aren't fond of being transplanted, I can tell you that they will do very well if you start them in two-inch soil blocks started in a cold frame. That is how I started mine this year and I had no transplanting issues whatsoever.

This is a flower I would highly recommend.

Tendrils grew rapidly (6" a day or more) and by July the vine had covered everything it could reach. I just pinched off any lower leaves that turned yellow. Buds began opening in August and each morning there are over a hundred new blooms. First time I ever had a plant that made people stop and stare! It is still going growing new tendrils with new buds and going crazy in mid-September. On cloudy days the huge flowers are open all day. Even a hail storm did not damage it. I let it latch on to some tall zinnias nearby and the combination of blue flowers on pink zinnias is amazing. I don't believe it ... read more

And the plants I had last year had several blooms that were mottled blue with pink spots...very strange! I am considering pulling up the pink blooming vines after I get a few more seeds...I will start them some where in the shade next year because these are very agressive seeders in the sun where they are now. I may have bought cheaper seeds, can't remember for sure what brand they were.

The name Grannywine is new to me since I know it as Clarke's Early Heavenly Blue. A consistant performer in the garden. As to the poster from Saskatchewan with the negative experience, I think trying to grow them in a hanging basket was the reason, not the variety of morning glory, plus the wind did not help. they like climbing on a trellis or twine or some other means of support.

I have a lot of morning glory vines, all volunteers draped all over the sides of my home. However, I have yet to get one single blossom this summer. It is already the 7th of September.
The plants are vigorous. I train them to cotton string which I stretch from the eves to stakes in the ground.
In previous years I had a lot of heavenly blues that did flower. I had hundreds of blossoms.
Last year there were two kinds of blossoms: heavenly blue and another very small pale purple flower. The small flower looks exactly like a morning glory except for the small size. Perhaps it is a hybrid.
However, this year I haven't even had one of those.

This is the first year that I have ever planted anything in the ground, and I am absolutely floored at how enjoyable it all is. The blue dawn that I have is growing every day and I love the time I spend fussing with it. I got 5 or 6 flowers the first weekend after I bought it and planted it w./ a 6' climbing trellis, but alas not many since. I believe it was getting too much shade during the hot Texas summers(which probably isn't all that bad, I guess), but I have cut back the tree that was covering it. I hope this helps as this is one very beautiful plant.

A couple additions:
Do not fertilize,
Do not lose your sympathetic gardener's wits if they wilt in 90-110 degree weather,
Do not overwater,
Do wake up early enough to see them,
Best growth is during heat,
Do not eat their seeds; silly, [I'm sure even landfill looks like Monet's garden after eating them. Sure, "Expand" your daft prune mind via cooking it.]
Growing them on a West fence/wall keeps the morning's flowers out of the sun longer,
Direct sowing when warm outside usually (always) works better than early-sowing indoors. {For reasons of seed-adaption and soil interface...}
and the true blue looks truer next to a red-impersonator like Ipo. Scarlett O'Hara.

That's all.

In reply to redjii, many newly-sprouted morning glories look "deranged" but grow up to be perfectly healthy plants. (There may be a parallel there with a few human infants I've seen!) Also, it is absolutely true that morning glories hate to be transplanted. They should be direct-sown, either in pots (which obviously can be moved) or in the ground. Transplanting--even with extreme care--is a recipe for disaster.

Heavenly Blue is my all-time favorite morning glory. (Some vendors sell it as "Clarke's Early Heavenly Blue," which may originally have been earlier but seems just the same now.) It has stunningly gorgeous flowers of considerable size, and it is way less aggressive/invasive than the purpurea varieties.

This is just a reply to Cnswift's comment. This is my fourth year growing morning glories, and I do have Heavenly Blue doing very well in my backyard.

The withered undergrowth at the foot of the vines is normal. This will not affect the vine's ability to grow and produce flowers. As the vine grows taller, the leaves at the bottom will eventually get old and die. If you want, you can plant a row of alyssum to screen the ugly stems. It works pretty well for me. Just make sure you don't water the morning glories too much. They prefer staying on the dry side. =)

And about the mottled growth, you may get mottled growth, again, near the foot of the vines. This is because you may have gotten dirt on the leaves when you were watering or if it was raining. The leaves a... read more

Do not plant morning glory in a windy, exposed area. It will wither and die within days, like the three I planted in a hanging basket. After being bashed about by the wind for two days, they all went limp, shrivelled and dried up.

This time I planted them in a sheltered location with a trellis to climb. They were much happier here, grew up the trellis and produced beautiful blue flowers.

The only issue now is the short growing season. I bought them as bedding plants and put them out in late May, after the danger of frost had passed. It took until early July for the vines to grow large enough to... read more

I live in Athens, Greece and planted Heavenly Blue last year that my aunt sent me from New England. I sowed the seeds in March and they grew like mad all summer and bloomed right up through December! I collected the seeds and am again growing this year, sowing in January this time. So far, there are millions of them. This time around, I noticed the dirty leaf phenomenum (thanks, Marshmellow), along with the wretched aphids and gently scrape them off not to harm the new growth, where they like to gather. My last garden was very shady and didn't get any light from September to April, and in the summer only a few hours, so they can also grow in minimal light although probably only when they have been established already in sun.

Growing Tips:
1. Probably the single most helpful tip is with a spray bottle of just water, or your hose set to a fine mist keep the leaves clean. In particular after every rain go out there and clean any dirt & debris that sprayed on the leaves (until the plants are over two feet tall). The leaves, in particular the two first leaves that look like a butterfly have a bad reaction to dirt. If the leaf collects enough dirt and itís left on there (which isnít much) they begin to warp and deform.

I grew these beautiful blue morning glories last year. They are definitely a joy to have in the garden. The only problem I had with them were the tiny little aphid-like bugs that love to eat them. The bugs swarmed my lovely flowers covering the back sides of the leaves. They made white spots on the leaves that eventually caused them to turn brown and fall off. I was very excited to see that they reseeded themselves and are about 2 in high now. The only thing is I am afraid of those nasty bugs comming back and taking over again.

I planted the Heavenly Blue in a small garden, mainly to cover an ugly cement block wall. It seemed that the hotter it got (temperatures exceeding 100F every day), the more the vine thrived. I had to cut it back vigorously. After I moved out and rented the house, I went back once a month to maintain the small yard. After a month the vines had grown into the grass, strangled all the plants in the flower beds, and almost covered the entire wall on both sides. I think this happened because it received water everyday via a sprinkler head.

So, my advice is to plant it where it has ample room to grow, and don't water it too much. But it is an excellent plant for color and foliage in a desert environment.

Morning Glory's hard-shelled seeds should be soaked in moist paper towel (folded over to cover seeds), placed in a bowl, covered with plastic wrap & placed on top of your fridge for at least 24 hours.
