At maturity, the typical Mallow Ninebark (Malvaceus) will reach up to 15 feet high, with a maximum height at 20 years of 15 feet.

The Mallow Ninebark (Malvaceus) is usually not commercially available except under contract. It can be propagated by bare root, container, seed. It has a slow ability to spread through seed production and the seedlings have medium vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -33°F. has high tolerance to drought and restricted water conditions.
