Lisianthus

Lisianthus is a long-cycle cut flower raised mainly from tiny, light-requiring seed. Conventional seed emerges in about 9-11 days, but producing a transplantable plug commonly takes 2-3 months. Cultivar, season, temperature, light, and production system can shift sowing-to-harvest from about 112 to 240 days. Tall cut-flower plants need horizontal support and a moist, aerated root zone. Recirculating NFT, fertigated perlite, protected beds, and field or tunnel drip production are directly supported. Nutrient demand rises sharply after visible bud, while excess post-bud nitrogen under weak winter light can delay opening and increase bud blasting. Harvest when one or more lower florets are open, hydrate immediately, and keep stored stems upright and cool.
