Big banana like leaves. Strelitzia nicolai is a great plant for a very sunny spot. Growth can be very quick with the leaves arching architecturally creating a fan. If you have the space it can flower but only after it gets to 2.5m+. In the mean time, you can admire the lovely gigantic leaves and long arcing stems.
It can happen that some minor tearing occurs in the leaves. Similar to fenestrations in a cheese plant, it uses these tears to allow sunlight to filter through to the lower parts of the plant and mitigate the effects of wind. Please do not worry if you receive your plant with some minor tears in the leaves, it is very normal and healthy.
