WaterPink Lily Leek, commonly known as Allium oreophilum 'Zwanenburg', should be watered deeply to encourage root development, requiring about 1 inch of water weekly during its growing season, typically in the spring. It's essential to allow the soil to dry out slightly between watering sessions to prevent waterlogging, which can lead to root rot. During the dormant period in summer, after the flowers have faded, reduce watering significantly, as this plant prefers drier conditions when not actively growing. An estimated gallon of water per week per plant is a good measure during its active growth, adjusted according to rainfall and soil conditions.
LightPink Lily Leek thrives best in full sun conditions, where it can receive at least six hours of direct sunlight daily. The best spot for this plant is in a sunny border or open area that is not shaded by taller plants or structures, as adequate sunlight ensures the most vigorous growth and best flowering performance.
TemperaturePink Lily Leek can survive in a wide range of temperatures but thrives in conditions between 60°F to 75°F. While it can withstand winters with temperatures as low as -4°F, it is essential that the plant is well-drained to prevent bulb decay. During the growing season, maintaining the temperature around the ideal range will promote healthy growth and flowering.
PruningPruning Pink Lily Leek is not typically necessary, but it is helpful to remove spent flower stalks after blooming to maintain a tidy appearance and prevent self-sowing if desired. Pruning should be done immediately after the flowers fade, usually in early summer. There is no need for regular pruning or shaping of this plant as it naturally maintains an attractive form.
CleaningNot needed

Life cycleAllium oreophilum 'Zwanenburg', commonly known as Pink Lily Leek, starts its life cycle as a dormant bulb, which is planted in the autumn before the winter sets in. As temperatures rise in spring, the bulb sprouts, producing slender, strap-shaped leaves, and a sturdy stem. The stem elongates and eventually bears a spherical cluster of star-shaped, vibrant pink flowers by late spring to early summer. Once flowering is completed, the plant goes through pollination, potentially with the aid of insects, leading to the production of seeds. After seed dispersal, the foliage of the Pink Lily Leek naturally dies back, returning the plant to a dormant stage during the late summer or early autumn. Throughout the winter months, the bulb remains underground, storing energy for the next growing season.

Spring to early summer
The most popular method of propagation for Allium oreophilum, commonly known as Pink Lily Leek, is by dividing its bulbs. This process is best done in the fall months after the leaves have died back, ensuring that the plant has completed its growth cycle for the year. To propagate, carefully dig up the clump of bulbs and gently separate them into individual bulbs. Each bulb can then be replanted at a depth of about 2 to 3 inches (5 to 7.6 centimeters) and spaced about 4 to 6 inches (10 to 15 centimeters) apart. This bulb division is an easy and efficient way to produce more plants while also helping to rejuvenate older clumps that may have become overcrowded.
