A landscape designer would have more fun describing both the modern and the good old fashioned varieties of morning glory. Their vivid colors are so resplendent. Their rich green foliage is so luxuriant. Their delicate vines are so elegant. Hey, perhaps this is not so difficult. Anyway, the popular garden varieties of morning glory are descendents of various species of the genus Ipomea.
Except for a few obscure types, and the perennial blue dawn flower, popular garden varieties of morning glory are surprisingly complaisant annual vines, which grow from seed sown at the end of winter. Without getting too invasive or weedy, they sometimes reseed where they get watered, although they might revert to a more feral state after a few generations, or after the first generation.
Some varieties of morning glory have the potential to reach single story eaves, although most stay a bit lower, and some varieties do not get much higher than a doorknob. They work well on small trellises, or even simple stakes, and are just right for picket fences. The simple two or three inch wide flowers are rich hues of blue, purple, red, pink and white, some with spots, stripes or streaks.

Another very serious NZ weed – very pretty in the right place tho’. Here these will cover entire re-vegetation plantings. And thanks for the like on my sculpture post.

You are welcome. The morning glory that is the invasive weed is most likely a perennial species that we know as the blue dawn flower. Annual morning glory can be a bit prolific, but should not be too difficult to control.

Our natives are quite pretty, and some of the cultivars are ‘glory-ous’ indeed. Apart from their beauty, any reference to them always makes me smile, because my dad used to wake me in the mornings when I was a kid by saying, “Morning, Glory.”

The only morning glory that is native here is bindweed, which is nothing to brag about. Perennial morning glory, which we know as blue dawn flower, can get quite weedy and invasive.

We have some interesting natives here – the one in the picture and Moonvine. Excellent non designer commentary!

Thank you. I now how to grow things, but not how to work them into a landscape.
Is moonvine a native morning glory, and is it perennial? The one in the picture is an annual. It just happens to be the same color as the perennial morning glory that we know as blue dawn flower.

The Moonvines are annuals and flower at night. They grow along the Indian River here and are a sight to behold in the early morning.

It is native? A white and seemingly annual morning glory appeared in the San Lorenzo River just a few years ago, and is not quite rampant. It is very pretty, but concerns me because it is an aggressively invasive exotic.

Yes, the blue one is native here as well.

I love the way they look lit from within. Yes, here, they’re a crazy weed. I pull them out a lot. But I do that with sweat peas as well–prolific seeders. Still, really beautiful.

Are they just a weed because they are so prolific? The perennial species, which I know as blue dawn flower, is much more aggressive, although it probably does not toss seed as prolifcally. It is what I would consider to be a weedy species.

I love Morning Glories. My favorite is ‘Heavenly Blue’. The only problem with them here is that they don’t bloom until very late in the season.

‘Heavenly Blue is rad! It looks like the perennial morning glory that we know as the dawn flower, but is not aggressive. It happens to be one of the old traditional types.
