Cut flower gardens and backyard borders are enriched by growing fragrant gilliflower. This mix's tall stems are studded with gathered rosettes of bloom, with a good number of single flowered forms appearing as well. Stocks do well where summer weather is cool (75F or less) and humidity is not sky high, elsewhere they will be less luxuriant and cycle out of bloom quickly. Stocks can be a bit temperamental, for they need an even hand in watering when germinating, and cool temperatures with no check to their development–provide even water, fertilization and roomy quarters during growing on before transplant. The rewards are great, however, for they have lovely flower rosettes in a wide range of hues and a spicy clove-like scent, especially pronounced in the early evening. Seedlings can be selected for doubleness. (After germination during growing on at cooler temperatures, it will be easier to see the different color seedlings, the pale green seedlings are doubles). Discard the dark green single-flowering seedlings if desired.
Final Spacing:
Add 1-2" of compost before planting. Apply an application of a balanced organic fertilizer once established and follow with high potash fertilizer such as kelp or tomato fertilizer.
Diseases & Pests:
Space 1' apart for good air circulation and water by drip irrigation or early mornings only to avoid leaf diseases. Do not overwater as this can cause root rots-an even hand here is beneficial. Flea beetles and cabbage caterpillars are common pests. Pick off or spray with organic insecticide to help control.
When to Cut for Bouquets:
Harvest when 1/2 of the florets are open.
