Answer: lantana

Dear Francesca,
lantana are plants native to the American continent, which have naturalized in most of the globe, in particular Lantana camara, widely used in Europe as an ornamental plant, is considered a highly invasive plant in Asia and Australia; it is a shrub with semi-persistent leaves, ie it behaves almost as an evergreen only if the weather conditions allow it: in the case of a very cold or very dry climate, during the months with short days it tends to lose all the foliage, leaving the branches bare; to resume sprouting and produce aromatic leaves, it must be in suitable climatic conditions, and therefore outdoors, with fairly high temperatures and good humidity. Generally it is not a good idea to pick up the plants at home during the winter; this because at home, in addition to being a false "spring" climate, the air is always excessively dry, and the plants are watered discontinuously. Even if the lantana suffers because of the cold, it is advisable to leave it outdoors during the autumn and winter months, possibly exposed to the elements; in this way it will be watered when necessary and will enjoy a cold and well-ventilated climate, with moist and fresh air. If the place where you live has very cold winters, with persistent and intense frosts, then you can put your lantana in a sheltered area, exposed to the south or east, covered with agri fabric, so that it does not receive the cold wind. In this way you have more chance that the plant develops following the seasons, and receives the right watering and the correct brightness. Lantana is however one of the last plants to sprout in spring, certainly not as early as forsythia or jasminum nudiflorum; therefore, if the leaves have fallen only because of the cool climate and a little dry, but the plant is fine, it should begin to sprout as soon as possible. If, on the other hand, the leaves have fallen for other reasons, such as shortages or excesses of watering, or an excessively dry climate, then your plant may not even recover, or have become permanently dry. To see if it is still alive, you can try to cut a few sprigs: if it is still wet inside, and has green parts, the plant is alive and is just waiting for climate changes to sprout. If instead the twigs are completely dry inside, your plant is now dead. Not knowing if he watered it this winter, if the ground was dry or always damp, if the air in the attic was dry or damp, it is difficult to make assumptions unfortunately.
