Elegant White Flowers for Bouquets

Alissa White F1 brings a soft, classic look to floral arrangements. Its densely layered petals create generous blooms that combine beautifully with blush pink, champagne, apricot, lavender and fresh green foliage.

Use it in an all-white bouquet or as a light accent among coloured flowers. The lightly fringed petals add texture, while the decorative rounded buds provide contrast to the open blooms.

The firm petals help reduce damage during harvesting and handling, and the strong stems support the large flowers.

Group 2 & Crop Planning

Group 2 describes the variety’s flowering response and helps growers plan production according to temperature and light conditions. It does not indicate frost hardiness.

Greenhouse growing provides greater control over the conditions needed to produce quality flowering stems.

Sowing & Germination

Lisianthus grows slowly during its early stages, so start seeds indoors well ahead of the intended flowering season. Provide supplementary lighting when natural light is limited.

• Sow one pelleted seed per cell, preferably in deep plug trays.
• Use a fine, moist, well-drained seed-starting substrate.
• Place seeds on the surface and do not cover with compost or vermiculite.
• Keep the surface evenly moist so the pellet coating can dissolve.
• During germination, the breeder recommends a substrate temperature of approximately 21°C.
• Once seedlings are established, grow on at approximately 17–20°C, with good light and ventilation.

For more uniform germination and to reduce rosetting, the Alissa culture guide recommends holding freshly sown trays at 5–8°C for approximately three weeks, before moving them into warmer conditions. This propagation method requires controlled temperatures.

Avoid prolonged high temperatures during early growth, as these can encourage rosetting and delay flowering stem development.

Transplanting & Care

Transplant when seedlings have four true leaves, before their roots become crowded in the cells. Handle the root ball gently and maintain the original planting depth.

Plant into fertile, well-drained soil. Keep moisture consistent, particularly after transplanting, while avoiding waterlogging.

Feed moderately and avoid excessive nitrogen. Support netting helps keep the long flowering stems straight. Provide regular ventilation when growing in a greenhouse.

Flowering time varies with growing conditions. Warmer temperatures, stronger light and longer days generally encourage faster development. The 70–77-day plug production period refers to the seedling stage, not the total time from sowing to flowering.

Cutting for the Vase

Harvest stems when two to three flowers are open. Place them promptly in clean water and use cut-flower food. Keep arrangements away from direct sunlight and heat to help preserve flower quality.

Eustoma grandiflorum Alissa White F1 combines abundant double white flowers, sturdy stems and elegant buds for beautiful home-grown bouquets.
