I have two plumbago plants, one in full sun and one in partial shade. The one in partial shade is about 3 feet tall and about 5 feet wide, blooms almost continually (especially in our mild winters), thrives on very little water and has never been fertilized in the two years I've had it. The one in full sun has never taken off and is pretty much the same size it was when I brought it home from the nursery; it might do better if it got more water, but the point of it was low water use. All in all, they are pretty plants and given the right conditions can get very large. I would recommend this plant for the back of beds to provide some height and also to fill in larger areas.

this plant blooms profusely and what gorgeous blooms they are!!! I saw this at the nursery and fell in love, buying it without knowing where it was going to go but knowing that I had to have it! I've since found a great place for it! Can't wait to see how it changes with the seasons and am looking forward to those gorgeous blue flowers coming back!

We have two of these lovely plants. One is growing in considerable shade and has darker blur blooms. The other gets a good bit of sun and is a lighter blue.
