In the dark chilly days of winter the scented pelargoniums come into their own. No flowers I admit then, but pick one up and you are immediately transported to balmy summer days. One of my favourites is LittleGem. This is a dwarf plant with abundant small deep rose-lavender flowers in summer. The leaves are greyish green and incised and said to have the scent of oil of turpentine, but I find it quite pleasant and mild. Little Gem is possibly a P.graveolens derivative and was introduced by Cannell's Nursery in the UK in 1910.
