|
The genus Ranunculus, family Ranunculaceae, includes 600 species of perennial herbaceous plants native to the Northern Hemisphere. Some species are: Ranunculus cortusifolius, Ranunculus asiaticus, Ranunculus gramineus, Ranunculus aconitifolius, Ranunculus bulbosus. Common names: Canary buttercup, Azores buttercup. This species is native to the Canary Islands, Madeira and the Azores. They are prenneous or biennial tuberous plants with hairy stems that reach 60 cm (23.6") in height. The lobed, palmate, vine-like leaves are up to 30 cm (11.8") in diameter and bright green. The small but attractive yellow flowers appear above the leaves. They bloom from late spring to early summer. They are rarely used in gardening but are recommended for undergrowth and to cover shady areas of the garden. Ranunculus cortusifolius needs a light shade exposure and a hot, humid climate. It does not resist frost. The soil can be normal garden soil with plenty of organic matter. Water frequently so that the substrate never dries out completely. They do not tolerate prolonged drought. Fertilize in autumn with compost or a little manure. Prune wilted flower stems after flowering. At the end of autumn they can lose their leaves but they sprout again in spring. They are quite resistant plants to the usual pests and diseases. They are propagated from seeds sown in spring. |
