At maturity, the typical Tailcup Lupine (Caudatus) will reach up to 5 feet high, with a maximum height at 20 years of 0 inches.

The Tailcup Lupine (Caudatus) is usually not commercially available except under contract. It can be propagated by container, seed. It has a rapid 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 -28°F. has medium tolerance to drought and restricted water conditions.
