Aiming to obtain Salvia hybrids with ornamental value and high drought resistance, for xeriscaping, crossbreeding was made with Greek Salvia species. S. fruticosa and S. officinalis when used as seed parent were successfully crossed with S. pomifera ssp. pomifera, S. ringens and S. tomentosa, while when used as pollen parent it only succeeded between S. fruticosa and S. tomentosa. The growth of S. fruticosa and the four hybrids, S. officinalis × S. pomifera, S. officinalis × S. tomentosa, S. officinalis × S. ringens and S. fruticosa × S. ringens, selected for their ornamental traits, was evaluated under limited irrigation and modification of the substrate with attapulgite clay. The hybrids S. officinalis × S. ringens and S. officinalis × S. tomentosa developed a compact plant shape and most lateral shoots, desirable characteristics for potted plants and xeriscaping. All hybrids, especially S. officinalis × S. pomifera and S. officinalis × S. tomentosa, survived water stress better than S. fruticosa. Modification of the substrate with attapulgite, under limited irrigation, caused a decrease in the above ground/root biomass ratio in some hybrids and in S. fruticosa increased the dry weight of the root indicating increased drought resistance.
