Height: 3 to 4 feet
Space: 2 to 3 feet
Sun: Full sun to light shade
Moisture: Dry to average
Seed: Can be a bit difficult to germinate. We've had success by pouring near-boiling water over the seeds and letting them soak overnight. This treatment is followed by 1 to 3 months of cold, moist stratification (mix the treated seeds with a medium such as sand, peat, or potting soil; moisten the mixture and refrigerate). Untreated seed also germinates; it just takes a bit longer. Sow untreated seed between October and late January.
