Red Valerian or Kiss-me-quick (Centranthus ruber (L.) DC.) is a herbaceous perennial originally from the Mediterranean Basin. It is a very hardy, vigorous species that can thrive in limestone soils and is resistant to drought. It normally grows to a height of about 60 cm and has shiny, green, spear-shaped leaves. It has pink or red flowers that are bunched together. Although it was only recently introduced into the gardens of the Alhambra and Generalife, it has quickly become an essential flowering plant. It flowers over a very long period in April and May, and blooms again in October. It is very attractive both when used en masse and when mixed with other flowers. Its leaves can also be enjoyed in salads or cooked as vegetables, which explains why they are planted in flower-beds near the vegetable gardens in the Generalife.
