Nemesia foetans ''Alba''

 This is one of my long-time favourite perennials.  Very hardy and easy to grow this nemesia is a must-have in every garden.  This beauty forms compact clumps of fresh green, pretty foliage which is topped with a mass of fragrant white flowers for months from early Spring.  Very happy in most soils with good drainage and will also do well in semi-shade.  Tolerates dry conditions beautifully!  Lovely as a cut flower in small posies too.  Cut back after the first flush of flowers and more will be produced, possibly right through the year.  Full sun, partial-shade.  30x25cm approximately.
