At maturity, the typical Prickly Rose (Acicularis) will reach up to 4 feet high, with a maximum height at 20 years of 1 foot.

The Prickly Rose (Acicularis) is usually not commercially available except under contract. It can be propagated by bare root, container, cuttings, seed. It has a moderate ability to spread through seed production and the seedlings have high vigor. Note that cold stratification is not required for seed germination and the plant cannot survive exposure to temperatures below -38°F. has low tolerance to drought and restricted water conditions.
