Rich buttercream-colored, 2-3," fully-double flowers. We chose the Arena series as a later-flowering group 3 (main season) series that can be planted along with an earlier group 2 series, such as the Mariachi series, for a staggered harvest. When planted at the same time, Arenas start to bloom approximately two weeks after Mariachis. Group 3, for late spring, summer, and fall harvest. Lisianthus is also known as prairie gentian, Texas bluebell, and showy prairie gentian. Pelleted Seeds. Ht. 24-36". Avg. 21,600 seeds/oz. Packet: 50 seeds.
DAYS TO GERMINATION: 10-15 days at 70-75°F (21-24°C).
SOWING: Transplant: Greenhouse production is highly recommended. Sow 12-13 weeks in deep cell packs before last frost. Light is needed for germination, but a fine layer of vermiculite covering the seed will help control algae growth. Keep the soil evenly moist, but not saturated and maintain 70-75°F (21-24°C) soil temperature. Provide good air circulation until emergence. Reduce moisture levels once emergence has occurred and allow to dry out slightly between waterings to prevent algae growth. After emergence, reduce the temperature to 60-70°F (16-21°C). Avoid stressing the plants with high temperatures over 85°C (29°C) and overwatering during this stage to prevent rosetting (the resting stage). Early transplanting is recommended. Transplant no later than the fourth leaf stage, approximately 55-60 days. Direct seeding is not recommended.
DISEASE: Applying Rootshield® Home & Garden is recommended to provide prolonged protection against root pathogens.

Plants can be Annuals (single growing season), Perennials (grow year after year), Tender Perennials (grow year after year in warmer climates; and in some cases when given special protection in colder climates), or Biennials (require two years to mature).
Hybrid: The offspring of a cross between two or more distinct parent lines, usually of same species, and selected for improved traits.<br>Open-pollinated: A non-hybrid variety that can reproduce itself in kind, demonstrating relatively stable traits from one generation to the next.
Use for Cut Flowers and Bouquets
Variety good for fresh cut-flower displays.
Variety that we have found, based on our trials, to be the best performers in a climate-controlled greenhouse environment.
