What are summer flowers?

Perfect summer flowers are usually very floriferous, usually annual or biennial bedding and balcony plants. Sometimes perennial summer shrubs are also referred to as summer flowers. They are not only an eye-catcher, but also a popular source of food for bees, bumblebees and Co. Warm yellow, red and orange tones put you in a good mood and shine from afar. This luminosity is then supported by more subtle accompanying colors such as blue and violet. Summer flowers with their bright colors are resting points for the eyes. Below is a small list of popular plants for balconies and terraces.

frequently asked Questions

When can summer flowers move outside onto the balcony?

Since some of them are sensitive to frost, they should only be placed on the balcony in mid-May, after the ice saints.

Can summer flowers bloom longer?

Yes, faded flowers should be cleaned regularly. This stimulates the formation of new flowers.

Do summer flowers need shelter during the winter?

It depends on. Perennials planted in pots should receive some light shelter in winter. Annual summer flowers only flower for one season and are then discarded. Others like fuchsias and geraniums can be overwintered indoors.
