Care Guide
Planting
Plant Rodeo Rose in full sun in heavy, moist clay soil - this is the one lupine that actually thrives in slower-draining soils that would rot other varieties. Space plants about 3 feet apart to accommodate their mature width. Plant in fall or winter for spring blooms, or sow seeds directly by placing them about a quarter inch deep; you can pre-treat seeds by pouring hot water over them and letting them soak to improve germination.
After Planting
Water moderately through the first growing season to keep soil moist while the plant establishes. Once established, you'll only need to water about twice a month in summer at most - this is genuinely a low-water lupine compared to its relatives. The biggest mistake people make is overwatering or planting in sandy, fast-draining soil; Rodeo Rose wants moisture and clay, not dry conditions. This is an annual, so expect it to complete its life cycle in one season, blooming winter through spring.
