A massive erect perennial when mature, A. hirta full of flowers surely is a sight in early spring!
However, I've found it not too easy to grow as the rapidly expanding rootstock will dig deep into the soil (or the pot) and is quite susceptible to humidity.
An airy but still humidity-conserving substrate within a massive container seems to be the only reliable cultivation recipe if not planted right into the open ground. A short, humid growing season in a generally dry climate is a must for this stunner!
