Nandina


Question: nandina


I want to know if the domestic nandina can resist the winters in the mountains (800 mt. Around s.l.m.) where the temperatures reach even around -20 °. Alternatively, can you put the pieris or the photinia? thanks. Sincerely

Nandina: Answer: nandina


Gentile Pinuccia,
the domestic nandina is a medium-sized shrub, native to central Asia and the Himalayan area; in spite of the rather delicate aspect, it is a very resistant shrub, in the cold, in the heat, in the drought; resists without problems to prolonged winters, with nocturnal minimums close to -15 ° C; in times of occasional frosts, particularly intense, it loses part of the foliage, as a defense, and therefore it can easily be planted even in colder areas. However, consider that even if the minimum temperatures in the place where you live can be very low, a lot depends on how long the thermometer marks -20 ° C; if an account is spent a month at -20 ° C, another argument is whether in the early hours of the morning the thermometer occasionally falls so low. In the first case you will see each year your nandina lose most of the leaves, to put them even more beautiful in the spring; in the second case your plant will look great, displaying its beautiful and large pinnate leaves even in the middle of winter.
Surely even the photinia and the pieris are suitable to live in the climatic conditions that indicate us, even if it may happen that the pieris is found with the buds scorched by the cold.
However, consider that the pieris is an acidophilous plant, and therefore if in your area the soil is particularly calcareous, you will have to take care to place it in peat soil, and periodically provide a soothing fertilizer; the photinia instead is very decorative, but only when it has new fire-red shoots, because for most of the year it is a normal hedge shrub, with large oval leaves, slightly shiny.
If I had to choose between the three I would certainly opt for the nandina, which has particular leaves, decorative stems, beautiful flowers and long spikes of coral red fruits, which remain on the plant even in winter. In addition to this, Nandina has the advantage of rarely falling ill, and of not being attacked massively by insects.
Consider that in China and Japan it is also called sacred bamboo, as the branches are used to decorate small altars, even those found in homes.
Place your nandina in a sunny area, with at least a few hours of direct sunlight every day (summer and winter), with a rich and very well drained soil; it does not require pruning or other special care.
