Miniature Pelargoniums are the smallest of all the zonal types. They do not usually exceed 12 cms. in height, although the flowers grow taller than the plant but in proportion. They originated from a variety called Red Black Vesuvius which has darkest green foliage and this still features in the majority of varieties today. They come in as many different shades and colours as the larger Zonal Pelargoniums, but with their compact habit, they make wonderful windowsill plants and you can grow many more in the same space as other plants.
