Gardeners' Notes:

I planted Morning Glories years ago to cover a dog kennel. The kennel has been moved but the vine still grows. It will creep along the lawn and is pretty when it flowers. However it has also creeped into my bed of winter onions/scallions and climbs those as well. It's far more dainty than a trumpet vine, but just as aggressive. I am in Iowa. Zone 4-5a and it comes back every year without fail. Hard frost doesn't actually kill it.

I have a lovely Blue Morning Glory in a small opening by my Front Door. Full Sun, not much water. Love it. Many have wanted seed but when I open the bottom of the flower where seeds usually are, there is nothing.

Any ideas why no seed

I love morning glories. I find it unfortunate that some people blame the vigorous nature of this beautiful flower instead of their own lack of planning in choosing where to grow it for their EXTREME dissatisfaction. Basically, most morning glories are very easy to grow, but where you decide to plant them should be concern number one.

This is a perennial here in lahore pakistan specially if winter cared. It blooms heavily in August-September but in some areas has longer blooming season. It is one of fastest vines i have ever grown. The ones in soil bed are much faster and vigorous than those in clay pot. Blooms open in early morning and closes at noon. Does not need much fertilizer and water to flower. Forget it if you want blooms.

I grow this in Southern Italy - now in its 4th year, self-sown volunteers now pop up. 3 seedlings moved to a new area this year covered the whole of it in no time at all! It CAN be invasive, but the seedlings are easy to recognise and I just pull most out as soon as I see them. Leaving 3 or 4 to an area is enough and I put a net up behind them for support. I have only just cut them down now, even though they are still in flower and we've not had frosts yet (and often don't), simply because I wanted to collect the seeds this year rather than let them fall to the ground. I've had loads to give away or swap, which is nice. I use cheap netting and cut the whole thing down, rather than try and extricate the dying vines from the netting.

In summary, great for covering an unsight... read more

It is commonly sold in Home Depot and other nurseries, where it's blooms last all day long because they are growing under shade cloths. Alough the blooms are nice, they dont last long out in the real world (outside of the nursery where they aren't under a shade cloth). In our 100+ degree summers the blooms fold up by 9 in the morning, and the rest of the day you're looking at a bunch of shaggy looking leaves. It is also etremely invasive and once you have it in your harden once, it is nearly impossible to get rid of. It is very prone to getting aphids and a load of other parasites and rambles over EVERYTHING, including brick walls, reseeding itself everywhere. Unless you live in a climate where frost and freezes can help you control this vine and where the temperature isnt 80 degrees as so... read more

While this plant can be invasive in areas that don't freeze, it is normally a well behaved vine in most of the country. If I had to choose only one plant to have in my garden, this is it.

If this plant is allowed to go to seed even once, you'll battle it for years ... especially if it is on a neighbor's fence and they don't help you battle it!
