This little pelargonium has been on The List for a while. The rich purple flowers, almost black from some angles, may be small but what they lack in size they make up for in dramatic impact. The grey downy heart-shaped leaves are perfumed, although admittedly not as strongly as many of the scented pelargoniums, forming a neat rosette. This plant is not only beautiful but clever (remind you of anyone?); it has adapted a thickened root system to enable it survive the regular grass fires that occur in its native South Africa. It also boasts medicinal properties, being used as a cold and flu remedy and is a constituent of many over the counter products. If none of the above impresses you, surely it is worth growing for the common name alone, Umckaloabo. Go on shout it out UMCKALOABA! It feels good, doesn’t it?
