The Casa Blanca Lily is an oriental lily that grows up to 4-feet tall and has numerous sweet-smelling white blossoms. A favorite of gardeners and cut flower growers, the Casa Blanca Lily is easy to grow, and the blooms can last for more than a week in a vase filled with water. The Casa Blanca Lily comes back from a bulb every year and multiplies rapidly. The white blooms of the Casa Blanca Lily can be as big as 10-inches across. After the bloom period, the foliage turns yellow and fades, but they should not be cut back until the foliage is completely dead.
How to Garden With Casablanca Lilies
Find a place in the garden that receives about six hours of direct sun per day. If you live in the Southern states, the Casa Blanca Lily will bloom in early summer and decline during July and August leaving the dying foliage visible. Therefore, find a place in the back of the garden or behind slower growing perennials where the blooms can be visible in the spring and the old foliage cannot be seen later in the summer. In cooler climates, they can be grown as a specimen plant in full view.
Clean the area of weeds and loosen the soil to a depth of 8 inches using a garden fork or shovel.
Spread a 2-inch layer of well-rotted compost over the area and work it into the top 6 inches of soil.
Plant Casa Blanca Lily bulbs three times as deep as the bulb is tall measuring the depth from the top of the bulb. For example, if the Casa Blanca Lily bulb is 4-inches tall, plant to a depth where the top of the bulb is 12 inches below the soil level. This is important because the tall plants will fall over easily if the bulb is planted to shallow. Spread a 1-inch layer of mulch over the planting area to keep area moist but not wet. The bulbs will rot if they sit in water.
Cut off old flowers before they go to seed and leave the green stems to naturally decline. The plants pull the energy from the old foliage to use for flower production the next season. If cutting flowers for a vase, don't cut more than 1/4 of the stem, leaving as much foliage as possible.
