RADYAN Pure White Mariachi Lisianthus F1 Seeds with Extra-Double Rose Blooms by

Pure White Mariachi Lisianthus F1 features large, extra-double (quadruple) rose-shaped flower heads measuring 2 to 2¾ inches. This Group 2 variety is favored for its elegant double and fringed flower types, often called the 'Rose Without Thorns.' It is suitable for winter sowing and early spring to summer harvest, providing excellent vase life with thick petals that reduce botrytis issues and maintain flower quality.

Growing Lisianthus from seed is not recommended for beginners due to the long growing period and temperature sensitivity. Germination takes 7-14 days, but plants require 8-10 weeks before transplanting. Maintaining cool night temperatures (55-59°F) and moderate day temperatures (72-80°F) is crucial to prevent rosetting and poor blooming. Proper watering is essential to avoid stress. Many growers prefer plugs to ease cultivation challenges.
