The tall herbaceous varieties of salvia form nice clumps and can grow up to 3.3ft (1m) every year. The shrubby varieties of salvia grow much more slowly and are easily pruned to keep them in shape. The annual varieties tend to be small, growing to around 7.8in (20cm), while the perennials can get to 4.9ft (1.5m) tall.
