Plumbago - ground cover

Does anyone grow this in their garden borders. It's very invasive but a lovely blue and nice foliage.

Do you keep cutting it back throughout the season, or just leave it alone. It does get untidy, but maybe a good plant to cover some spaces, but in a border, I'm not so sure!

Any input would be appreciated - thank-you!

I know Plumbago to be tropical and in my experience it couldn't overwinter in my yard. Have you been able to overwinter them outside? It's used more as annual here in Ontario but if it survived then it's telling more about climate change.

Hi Ianna'

This one is like a groundcover, roots that spread as far as you want them to.

I am in southwestern Ontario, and it overwinters with no problem, spreading more every year. Shows itself in late April/early May, nice foliage,slightly bronzey, then later, vivid blue flowers. It does start to flop, esp. in the rain, and looks a bit untidy. I haven't noticed any bug problems with it.

I must learn to put a picture on the forum when I'm asking for advice! My next challenge!

I have this hardy plumbago in my border in Toronto since last summer - In my border, it is not invasive at all, it has healthy shiny foliage, looks neat, but does not bloom quite long enough for my liking in my small border, and the flowers are not really visible from a distance (it does not make a big splash) - that's my only complain.

Is this the same kind of plumbago used on trellises. (I've seen one set up on teepee form trellises) Light green leaves and light blue flowers? I would love to have that growing on my borders.

my plumbago is not a runner . Grows quite prolifically but is not a runner or ground cover . Never heard of one that was . Are your positive what you have is Plumbago? Mine is really an upright shrub ....lovely blue phlox type flowers.

I grow my plumbago (Ceratostigma willmottianum) in one of my dry borders, and it makes it through the winters with only a bit of die-back each year, so stays well within bounds, and provides a beautiful blue backdrop for miniature gold iris and looks great beside the yellow foliaged oregano

The tender plumbago (Plumbago auriculata, capensis...) is tropical (or sub-tropical) and grows great in the warm greenhouses, and even makes a great house plant

The common name of the plumbago that I have is Leadwort, otherwise Cerastostigma plumbaginoides.

I think the plumbago that Ianna has seen growing up a teepee type trellis sounds like orchidguy4ever's Plumbago auriculata,capensis. I've seen it in greenhouses, and thought about having it as as a house plant, but I've also seen it in a summer garden.

Purple-anenome, I think your plant is the same as mine, and when it comes up next year, you will find that it has spread a little, then it will take off! Next year the lovely blue flowers might stand out more.

For people who live in Toronto there is a plumbago growing in front of Indigo Books. There are two climbing plants in large planters on both sides of the door facing Bay street in the Manulife Building at Bay and Bloor. Every spring the plants are placed outside until fall when they are removed. I believe the plants spend winter in the greenhouse. In early years the plants looked much tidier. Now they look a bit scraggly, They need a trim. Maybe someone could bring this to Heather Reisman's attention. After all she was so keen on gardening that she bought Cruikshanks, which has existed since 1929, and managed to run it into the ground. Cruikshank was a bulb specialist and I still miss them, sold great stuff. Now we have Garden Import, which many find expensive. There's Breck's and it's not any better.

Yes I was referring to the tropical plumbago. Beautiful sky blue flowers.

RE: Plumbago - ground cover

I just planted the groundcover version of this. I love it! I'm so anxious that it won't survive the winter. I've planted 3 on a steep slope and they nearly died from lack of water. I shoved some bottles of water into the ground to get water to the roots and they stopped dying, but I can't do that all winter. Any suggestions? I adore the intense blue colour and I need the erosion control.
