The young plants of Erodium pelargoniflorum and Geranium maderense are growing well. They are of the geraniaceae family which includes pelargonium,
Erodium pelargoniflorum also known as herons bill and “sweet heart” has the foliage of an Erodium and the flowers more like a pelargonium, the petals are white with pink -purple blotches in the centre and prefers full sun to part shade in well drained soil. Geranium maderense (cranesbill) is native to the Island of Madeira and attracts butterflies and other insects, also known as the giant herb Robert, it has dark green leaves and large purplish pink flowers that grows up to 150 cm (5 inches) in well drained chalky, clay, loam, sandy soil types.
Erodium pelargoniuniflorum also known as sweet heart or heron’s bill has attractive pale pink flowers that are similar to a pelargonium because of the darker markings on the upper petals which many pelargoniums possess, it was given the name pelargoniflorum because of the pelargonium like flowers.
This plant is native to Turkey and can grows up to 30 cms in height with petiolate leaves. There are about 182 species of erodium which are included in the Geraniaceae family.
The name Pelargonium was originally classified as a Geranium in the early years of discovery but the botanical name was later suggested by Dillenius in his botanical works and illustrations which included 7 species of Geraniums from South Africa and was based on the Greek word pelargo’s because the seed head has the appearance of a storks beak. Johannes burman a Dutch botanist and physician in 1753 mentioned the differences in species and organized them into the same genus Geranium, The name Pelargonium however was not actually established until Charles Louis L’H’eriter de Brutelle a French botanist and magistrate classified the pelargonium by the quantity of stamens in the flower, in which most pelargoniums have seven and divided them into two different genera. De Candolle in 1824 again split the genus into 12 different sections to show the different types of pelargoniums, some having longer petioles, thicker roots or leaf shapes etc, later extended to 16 sections by Knuth 1912.
The sections include Campylia, Chorisma, Cicronium, cortusina,Glaucophyllum,Hoarea,Isopetalum, Jenkinsonia,Ligularia,Myrrhidum,Otidia,Pelargonium,Peristera de Candolle,Polyactium de candolle,Reniforme,Subsucculentia
