Sage (Salvia ×superba): A Reliable Perennial for Color and Pollinators
If you’re looking for a dependable perennial that delivers months of vibrant color while keeping maintenance to a minimum, sage might just be your new best friend. This hardy hybrid brings European charm to American gardens with its striking purple-blue flower spikes and silvery-green foliage that looks good from spring through fall.
What Is Salvia ×superba?
Salvia ×superba, commonly known as sage, is a perennial hybrid that resulted from crossing two European sage species. As a forb (basically a fancy term for a non-woody flowering plant), it forms neat, compact mounds that burst into colorful flower spikes year after year. Don’t let that × in the name intimidate you – it simply indicates this plant is a hybrid, and a particularly successful one at that!
Where Does It Grow Naturally?
While this sage hybrid has European parentage, it has naturalized in parts of the United States, including Ohio, where it reproduces on its own in the wild. As a non-native species that has established itself successfully, it demonstrates remarkable adaptability to North American growing conditions.
