Why Choose Lisianthus Can Can Carmine Rose

This variety is prized for its vibrant carmine-rose petals and long-lasting blooms, making it a perfect choice for cut flower arrangements.

Step-by-Step Guide to Grow Lisianthus

1. Start Indoors

Lisianthus seeds are small and slow to germinate, so start them indoors about 10–12 weeks before your last frost date. Use a fine seed-starting mix and gently press the seeds onto the surface—do not cover them, as they need light to germinate.

2. Provide Warmth and Light

Keep the soil temperature between 70–75°F (21–24°C) for germination. Place the trays under grow lights or in a bright, sunny window. Expect germination in 10–15 days.

3. Transplant Carefully

Once seedlings have a few sets of true leaves, transplant them into individual pots to develop strong root systems. Lisianthus roots are delicate, so handle them gently.

4. Prepare the Garden Bed

Choose a sunny spot with well-drained soil enriched with compost. Lisianthus thrives in fertile, slightly alkaline soil. Space plants 6–8 inches apart to allow good airflow and reduce disease risk.

5. Water and Feed

Keep the soil evenly moist but not soggy. Use a balanced liquid fertilizer every 2–3 weeks to encourage steady growth and abundant blooms.

6. Support Tall Stems

Lisianthus can grow tall, so consider staking or using flower netting to support stems, especially in windy areas.


Bloom Time and Harvest

Lisianthus blooms in mid-to-late summer, rewarding your patience with waves of elegant flowers. For cut flowers, harvest when one or two blooms on the stem have opened. This encourages more buds to develop and extends your flowering season.
