Salvia officinalis
Many interspecific hybrids occur naturally, with a relatively high degree of crossability, but some such as "Salvia officinalis" × "Salvia lavandulifolia" and "Salvia fruticosa" × "Salvia tomentosa" have been intentional. A natural hybrid, "Salvia longispicata" × "Salvia farinacea" has given rise to a series of popular ornamentals such as "Salvia" 'Indigo Spires' and "Salvia" 'Mystic Spires Blue'.
