This plumbago is one of two that I kept in big pots on my balcony. The unusual blue flowers are simply gorgeous! These grow best in full sun and don't like to be overwatered. I live three floors up in an apartment building and this was the first plant on my balcony to attract hummingbirds. 💖💖💖
My plumbago plants tend to bloom in flushes. After every flush I trim off the spent flower shoots, remove the top layer of potting mix and top up with fresh soil, fertilizing with slow release pellets at the same time. If you grow them in the ground this consistent renewal and fertilizing isn't necessary; plumbago will spread and drape and thrive in regular soil once it gets lots of sunlight.
Confession: I became so enchanted by these sky blue flowers that I went in search of other plants with blue blooms for a section of my future yard that I plan to call "The Blue Garden". It's going to be beautiful.
