I planted a (Monrovia) Tropicanna Canna in a sunny location almost 4 weeks ago. It gets sun from late morning to late afternoon. The leaves on the Canna are losing the burgundy and red color and currently looks green with yellow stripes. New leaves emerge with the color of red, burgundy, green and yellow, but seems to eventually fade to green and yellow only. The plant gets watered every 3-4 days for about 20 minutes each time, and I do check to make sure the soil is moist. What can I do to get the burgundy and red colors back into the leaves? |
There are a number of cannas featuring brilliant foliage, and what you describe sounds normal for 'Tropicanna'. It has hot orange blooms over purple foliage that becomes striped with green, yellow, pink and red. As the foliage matures it changes colors. There's really nothing you can do to make the foliage hold its burgundy color - the color change is normal and natural for 'Tropicanna'. If the blooms are yellow rather than orange, you may have 'Minerva' rather than 'Tropicanna'. The foliage on 'Minerva' is green with yellow stripes and no red or purple at all. Hope this clarifies things for you! |
