Plant of the Month



Of the family Tropaelaceae, the Nasturtiums range in growth and habit from climbing, trailing, or bushy annuals to herbaceous perennials, many with tuberous roots. Tropaeolums are native to the cool, mountainous areas of Central and South America and are usually grown as cool season annuals in South Florida. The leaves and flowers of these annuals are often edible, and the young fruits of T. majus can be pickled.
