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

The Desert Globemallow (Ambigua) generally appears in field collections and doesn't tend to be commercially available. It can be propagated by 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 -6°F. has high tolerance to drought and restricted water conditions.
