Propagation techniques for three Mediterranean native shrubs with potentential as ornamental outdoor plants

Grande are three Mediterranean shrubs with interesting ornamental features. The exploitation of wild plants for ornamental purposes implies knowledge on the factors influencing the propagation methods. To study the influence of temperature on germination, seeds of Teucrium flavum, Prasium majus and Micromeria fruticulosa were germinated in incubators at constant temperatures of 14, 20, 24 and 28°C. Highest germination, 45 % and 86%, occurred at 20°C in Teucrium flavum and Prasium majus, respectively. Micromeria fruticulosa seeds subjected at 24 or 28°C had a germination percentage significantly higher than at 20 or 14°C. To study the influence of auxin treatments on vegetative propagation, …

Leonotis leonurus (L.) Br. Pubesc., also known as “lion’s ear” is a perennial shrub belonging to the Labiatae family and native to South Africa. The name of the genus derives from the Greek words leon (lion) and otòs (ear).
