Which plants you can plant on the balcony in March. Not all flowering plants in the garden center are frost resistant.
But if you don't want to go without flowers in March, you will find a selection of robust flowers there. You should not plant dwarf irises, begonias, daisies or geraniums outside yet. They are quite sensitive to frost and only come out into the fresh air in May. In March you can also plant frost-resistant summer bloomers. These include the bellflowers such as the Dalmatian bellflower.
