Planting & Care

For best results, scarify seeds by nicking the hard coat or soaking in warm water for 24 hours before sowing. Start seeds indoors 6–8 weeks before the last frost or sow directly outdoors after the danger of frost has passed. Press seeds into the soil surface and cover lightly, as light aids germination. Keep the soil consistently moist but not waterlogged. Germination typically occurs in 14–30 days at temperatures around 65–70°F (18–21°C).

Once seedlings have developed a few true leaves, transplant them to their final location. Water regularly during the first growing season to help establish a deep root system. Mulch around plants to retain moisture and suppress weeds. Deadhead spent flowers to encourage additional blooms and prevent self-seeding if desired. In hot climates, provide afternoon shade to protect plants from intense heat.
