Tower mustard is a slender, upright biennial or short-lived perennial that performs best in well-drained soils with partial shade to full sun exposure. It requires minimal care once established and is an excellent choice for wildflower meadows or naturalistic garden settings. Water regularly during dry spells, and ensure good drainage to prevent root rot.
