Question: Sanseveria

Can Sanseveria be a garden plant?

Answer: sanseveria

Dear Venus,
Sansevieria is a plant native to central Africa, very common in apartment cultivation; it is an evergreen perennial herbaceous plant, with rhizomatous roots. In fact, despite the fact that the Sanseverias are grown in Italy almost only in the apartment, they can also withstand quite low temperatures, and even short and light frosts, with temperatures close to -2 ° C.
The problem of life in the garden, however, is not given only by the temperatures: many succulents could live at the temperatures present in the garden during the winter, but only on condition that they have a completely dry soil.
The rhizomes of the Sanseverias suffer greatly from excessive humidity; in particular, the colder it is, the less water they tolerate around the roots; for this reason life in the garden is quite complicated, given that Italian winters, and even autumn, are characterized by a fairly humid climate.
So if you want to keep your sanseveries outdoors, you will need to place them in a place where you can control the amount of water they receive, and then also shelter them from the weather during the cold months.
You can work around this problem in two ways.
The first is to plant the plants in an area of ​​the garden sheltered by a roof or a pergola, so that they only receive water from the watering, which you will have to supply, and which you will then suspend in the autumn.
The other method involves covering the plants and the area surrounding them with plastic film during the coldest months.
If the sansevierie receive water during the months of frost, the rhizomes rot, causing even the long, fleshy leaves to die quickly.
But if you can find a suitable place in the garden, they will develop a lot and become very luxuriant; in addition to this, after a period of winter vegetative rest, it will be much more likely for you to see the sanseveria flowers, which bloom in corymbs, carried by long branched stems; Sanseveria flowers are not particularly decorative, but they are very fragrant, so much so that their scent is sometimes excessive.
If you are worried about the health of your plants, you can try growing them outdoors in a pot in the first year, so that you can move the pots under a roof, or on the terrace, when the cold comes.
