Rudbeckia hirta is botanically more accurately a short-lived biennial or perennial, though it's most commonly grown as an annual since it typically blooms in its first year from an early sowing.

Yes, Rudbeckia hirta self-seeds readily and is commonly used to naturalize meadow or wildflower plantings over time.
Why is Rudbeckia hirta generally considered deer-resistant?
Why is Rudbeckia hirta generally considered deer-resistant?
Its species name "hirta" means "hairy" in Latin, referring to its bristly, textured foliage, which tends to deter deer browsing compared to smoother-leaved plants.
Will this variety bloom in its first year, given it's sometimes classified as biennial?
Will this variety bloom in its first year, given it's sometimes classified as biennial?
Yes, despite technically being biennial in nature, Rudbeckia hirta is typically grown as an annual because it reliably flowers in its first season from an early spring sowing.
