After the tulip, the lily is the most important Dutch flower bulb. There is an extraordinary, thriving trade in lily bulbs. These bulbs are sold and used for flower production, worldwide. What's more, the processing arm of the lily cultivation flourishes better than any other branch of the Dutch flower bulb cultivation.
Lilies have been popular for a long time, and many growers have done their best to find the perfect cut lily. Unfortunately, no one ever took care of the potential suitability as a garden flower. Only recently fate changed for the better: under pressure of the increasingly stringent environmental regulations, there is a greater need for stronger lilies, lilies with improved vigor and less disease susceptibility. The solution was found in the so-called species lilies and trumpet lilies, lilies that are exceedingly strong. Not optimal as a cut flower, but unbeatable as a garden flower!
A lily in the garden can be best used as a perennial species. They are strong enough to survive the winter. The planting season runs from November to March. Do plant lilies as early as possible. It is advised to plant immediately after receiving them. If it is not possible to plant the bulbs, due to frozen ground for example, store the bulbs cool, protect them from frost, and make sure that they do not dry out too much.
A lily likes to be planted rather deep, keep at least 15 cm of soil above the top of the bulb. In addition to the roots below, the lily bulb produces so-called stem roots as well, which grow above the bulb, still underground. These roots play a significant role in lily growth, if lilies are planted less deep, the lily will not be as successful as one might expect.
