Every year, greenhouse growers make their mortgage note selling Easter lilies Lilium longiflorum. In an era where people so often want the new shiny thing, it is one of the longest running and most popular crops in greenhouse production history. Growers who know how to produce this crop consistently are highly sought after in the trade.
Making an Easter lily bloom on Easter weekend takes an enormous amount of planning and good horticultural skills. It takes about 23 weeks from initial potting to Easter for a greenhouse to produce a fully bloomed Easter lily. This includes a 3-week period for root development, 6 weeks of cooling to initiate bud development, and then 14 weeks of 'forcing' in the greenhouse to mature the plant and flowers. If you mess up somewhere along the way your crop may bloom too early or too late and be worthless.
