Casablanca lilies boast showy white flowers that generally measure between 10 and 12 inches with bright red stamen in the center. Perennials that are hardy in zones 3-8. Casablanca lilies grow between 3 and 4 feet tall and bloom in the mid to late summer. The sweet fragrance of Casablanca lilies will standout in any garden and the beauty of the blossoms will take your breath away.
Select an area of your garden with full sun. Test the soil in the area where you plan to plant Casablanca lilies. These showy flowers prefer a pH level of 6.0. You can adjust the pH levels as needed by adding lime to increase alkalinity or adding sulfur and peat to increase acidity. Casablanca lilies also love soil that is high in potassium. You can supplement the potassium level of your soil with fertilizers and potash.
Check to make sure that the soil drains well where you plan to plant the lilies. Water the area well, and then watch to make sure that the water has drained away within 3 hours.
Plant Casablanca lilies during the fall, about 12 inches apart. Dig a hole that is three times as deep as the Casablanca bulb is long. Place the bulb in the hole with the roots down and then backfill with soil over the bulb.
Water the newly planted bulb well. Cover the soil over the bulbs with a 3-inch layer of organic mulch. Lilies prefer soil that is evenly moist, even in the most dry conditions. Water daily during a drought or in the hot summer months.
Fertilize your Casablanca lilies in the spring when new growth first appears and then again in the summer when the flowers begin to bloom.
Remove each of the blooms after they are spent. When all the blooms have finished, cut the stem just below the last flower, leaving as much greenery as possible. The stem will continue to feed the bulb until the lily goes dormant. Cut the foliage at ground level in the late fall.
