Coleus (Solenostemon scutellariodes) isn’t just about variegation and it isn’t just about colour. It’s about BOTH. The foliage has almost as many variegation patterns as it does colour choices. And there are more named varieties introduced every year. Colours range from hues of green and yellow to red, pink, purple, bronze and orange—some solid, some variegated in beautiful patterns. These popular annual plants with colourful leaves typically grow 10 to 15 inches tall and also feature summer flowers.
Lavender is one of the most colourful—and fragrant—herbs. The flowers dry nicely and are often put in potpourri or bundled in sachets and kept in a sock drawer.
