Gironde is a yellow flower cultivar of perennial Asiatic lily that looks delicate and exotic, but is actually low maintenance and very sturdy in constitution. Like all Asiatic lilies, gironde produces large clusters of flower buds atop tall, slim and stiff stems. The flowers bloom in a cascade. They are prized as cut flowers for their color and form as well as for their long vase life.
Locate your gironde lilies in full-sun exposure to ensure the most abundant bloom. Some afternoon or lightly filtered shade is tolerated but it may impact the amount of flowers produced. Grow the lilies as garden perennials in USDA zones 5 through 9 and as container plants or annuals in cooler climes. Provide ambient overnight temperatures between 50 and 60 degrees Fahrenheit.
Planting and Growing Conditions
Plant your Asiatic lilies in the fall or spring for late spring and summer bloom. Temperate and warm climates will see the plants bloom into fall. Plant the bulbs deeply in nutrient-rich, well-drained soil, allowing 3 to 4 inches of soil from the top tip of the bulb to the soil surface above. Water well to keep the soil evenly moist but not consistently soaking wet. In dry or warm climates, a few inches of organic mulch may help to keep the soil moist.
Harvest the flowers for use in cut arrangements when at least one, and preferably two, of the buds have begun to open. Cut the stem down at the base of the plant and put into water immediately. When leaving the flowers on the plant, prune back the stalk after all of the flowers atop each stem have opened and died back. Again, remove the entire stalk, cutting it at the crown, and discard. Removal of spent flowers will help to encourage the development of new stems.
In the fall, after the top foliage has yellowed or died back, cut off the remaining plant material down tot he crown and discard. Mulch over the bulbs with 3 to 4 inches of mulch to protect them from temperature fluctuations and winter drought conditions. Uncover the bulbs from the mulch in the spring after the last frost to allow new growth to emerge. If the soil feels dry and rain has not been plentiful, begin a light, weekly watering regimen.
