There are different plants that are suitable for the balcony and which are also hardy enough for the winter.
You can use a lot of trees that also thrive in the garden as balcony plants. Of these, my absolute favourite is the serviceberry, a woody plant that impresses in spring with its flowers, in summer with its edible berries and in autumn with its colourful leaves. However, serviceberries require a little more space. Climbing plants, such as woodbine and Boston Ivy can also be found on balconies time and again. They are particularly noticeable in autumn owing to their red leaves.
Herbs in pots are suitable for small balconies. Sage, thyme and lavender remain green even in winter. In order to get a variety of colours on the balcony in the spring, bulb plants such as squill, tulips, crocuses and so on can also be grown.
All of the plants mentioned are hardy and perfect for the balcony because they can tolerate the sun and dryness well.
