A blue flowering plant is a rarity in South Florida landscapes, and blue plumbago plays well with others, colorwise. It's especially nice combined with other plants with silvery foliage and those with pink, yellow or white flowers. There's even a lesser-known white plumbago. The flowers resemble those of phlox, and the petals are slightly sticky (like Post-It Notes). When trimming the plant - or brushing by it - expect to find little blue flower petals clinging to your skin or clothing. The plumbago plant has a spreading, rambling habit that works best in an informal, naturalized setting, cottage garden or English garden style landscape design.
