• A native of the Mediterranean region, " Centranthus ruber " has been introduced into many other parts of the world as a garden escape.
• Because it can tolerate the lime in mortar, " Centranthus ruber " may frequently be seen growing in old walls in Italy and Southern France and South West England.
• Red valerian, often grown in gardens, is also sometimes referred to as " valerian ", but is a different species ( " Centranthus ruber " ) from the same family and not very closely related.
• Some " Centranthus " are known as introduced species in other parts of the world, including " Centranthus ruber " in the western United States and " Centranthus macrosiphon " in Western Australia.
• Plants that are affected at low levels, like red valerian ( Centranthus ruber ), clematis, lilac and baby's breath, need an application of lime whenever a soil test shows the pH to be too acidic, because in acid soils the metals can be absorbed.
