In urban green spaces, flowering plants are frequently grown in raised beds mainly to improve soil conditions and water regime. Along streets and boulevards, raised beds are often planted with resilient flowering plants that require minimal maintenance, such as lavender. Effects of the planting method on growth and flowering were investigated on young lavender plants grown in raised beds and at ground level. The results revealed that plants cultivated in raised beds were smaller in height and diameter at the end of the growing season. Also, flowering duration, size of floral stems and flower production were significantly lower, comparing to those grown at ground level. At the end of the second year of growth, lavender plants cultivated at ground level were double in size and produced a significantly increased amount of flowers. Hot and dry summers should be considered for flowering bedding plants in urban green spaces.
