It has midgreen leaves with a pale green midrib growing about 2.5 cm a day in summer, reaching up to 1.8 m long or more and 0.5 m wide, in other words -huge! The pseudostem (stem/trunk) can reach 2.7 m tall, making large plants up to 5.4 m high and 3.65m across, with long arching leaves.
With time it will become a clump-forming/spreading, multi-stemmed plant. With age each stem produces drooping pale yellow flowers with brownish bracts, followed by small green inedible fruit. Flowering stems die after fruiting and are replaced by many new pups around the base. The stem can take several degrees of frost (with protection, –10°C and lower), though leaves tend to burn at –2°C. The stems if killed will re-shoot from the ground in spring, hence the common name Japanese root-hardy banana.
