Canna ‘City of Portland’ gives your terrace or balcony a tropical look. This variety produces red flowers that contrast beautifully with the dark foliage. Cannas originate from the tropics. So they like a sunny spot. Canna looks great in a spacious flower pot or planter. Take a large pot with holes in the bottom. Cover the bottom with potsherds or a layer of hydro grains. Put potting soil in the flower pot and set the Canna’s root ball at the correct height. Fill with soil and press firmly. Water generously immediately after planting. Place the flower pot or planter in a spot in full sun. The flowers and the large dark leaves of the Cannas are indispensable in a border that has a ‘tropical’ character. Provide a sunny spot so that these tropical plants feel at home. Canna tubers, like dahlias, are very easy to overwinter. Remove the tubers from the pot or from the open ground after the first night frost. Place the Cannas in a crate with peat dust or sand. You can share large Canna tubers right away. Store the Canna tubers in a frost-free area. You can plant them again next spring (after the last frost).
