Perovskia atriplicifolia is a perennial herbaceous variety that develops a woody shrub, native to Asia.
It produces woody or semi-woody stems, quite branched, which give rise to a small roundish shrub, even 90-100 cm high; the foliage is greyish-green, semi-evergreen, with deeply divided leaf blade, quite thick and wrinkled; if crumpled, the leaves give off an intense scent of sage. From late spring to the summer, small blue flowers, similar to lavender flowers, gather in long spikes at the apex of the stems. The long flowering and the decorative foliage make the Perovskia a plant much appreciated in small hedges, but also as a single specimen.


The Perovskia atriplicifolia loves the sun and it is advisable to plant it in a sunny place, or to enjoy at least 4-6 hours of direct sunlight a day; these plants do not fear the cold, although it can happen that very cold winters cause the complete drying out of the aerial part, in general then the plant develops without problems in the spring heat.
For the youngest and most sensitive plants it is recommended to protect them in case of particularly cold and cold winters, covering the surrounding ground with straw and dry leaves that mitigate the winter rigor.
To keep the shrub more compact and dense it is advisable to cut the plants up to 15-20 cm from the ground, in January-February.


The Perovskia they are rather rustic and resistant shrubs and do not need very frequent watering; in fact they are also able to without problems even prolonged periods of drought. Generally during the spring months they can be satisfied with the rains, needing sporadic watering during the summer months, especially in dry periods or with very high temperatures.
Of course, if they are planted in pots, then they will require more water.


This type of plant is also cultivated in the common garden soil, however it prefers sandy soils, very well drained, with a good quantity of organic material.
The important thing is that the earth does not retain too much water, because stagnant water is rather dangerous for its health.
It is good to check that the soil allows proper drainage, otherwise it is very easy to run into problems related to the onset of mold or a root rot that can cause the plant to die.


The multiplication of this type of plant occurs by seed, in spring, or by semi-woody cutting in summer, taking the cuttings from stems that have not produced flowers. The new seedlings will have to be left for a while at the re-opening before being transplanted into the ground.
