Nemesia fruticans is a free flowering perennial that is sometimes treated as an annual.
It has slender stalks covered with many serrated leaves which tend to be thicker closer to the base.
The stems hold pretty and quite delicate, open-faced, fragrant flowers that come in a variety of pastel shades from lilac to pink to white and resemble snap-dragons.
These are the perfect rockery plant but also go well in mixed borders and pots.
