How to plant
In this section we will learn how to plant Purple sage (Salvia officinalis ‘Purpurascens’), know its needs in terms of soil, watering and sun exposure.
Purple sage (Salvia officinalis ‘Purpurascens’) is not a demanding plant regarding the type of soil and can grow in chalk, loam or sand.
The chalky soil is pale and contains chunks of calcium-rich rock. It is a fertile and well-draining soil, almost always alkaline.
The loam soil is dark, rich in organic matter but balanced in minerals. It offers the best of all worlds, retaining enough water for the plants, but allowing excess moisture to drain away. This is the most desired type of garden soil, perfect for most plants.
Sandy soil is light, porous and very easy to drain. It is a soil poor in organic matter and nutrients. It is composed of relatively large mineral particles that allow water to drain quickly.
It is not very sensitive to soil acidity or alkalinity and grows well in soils with pH acid, alkaline or neutral.
Regarding drainage, Salvia officinalis ‘Purpurascens’ likes to grow in moist but well drained soil.
Purple sage (Salvia officinalis ‘Purpurascens’) should be grown in full sun places.
