In Colorado, Are Lilies Growable?

Lilies are a popular and beautiful perennial plant that thrives in Colorado’s harsh climate due to their drought tolerance. They require little maintenance and bloom best with 6-8 hours of sunlight. In Colorado, it is best to plant lily bulbs as soon as the soil warms up to 45°F, usually around April or May, to give the bulbs time to grow before summer. Daylilies feature strap-like, arching foliage that provides strong texture in the garden from spring through fall.

Some lily types, such as Orientals, trumpet lilies, and tiger lilies, prefer lots of sunshine and cannot tolerate soggy soil, making them perfect for Colorado’s drier climate. True lilies are hardy in our area and are best planted in spring. There are two main types of lilies: Asiatics and Orientals.

The ideal time to plant lilies in Denver Metro is in October, as fall planting allows the bulb to put down anchoring and sustaining roots. Lilies can be grown in containers in cold climates, placed in larger pots in the sun, or planted in sunny areas of the garden. Lily bulbs should be planted in autumn, 4-6 weeks before frost in zones 4-8, in a spot that will provide at least 6 hours of sun.

Daylilies are one of the easiest perennial flowers to grow in the Colorado Springs area, with many cultivars available. They grow as large clumps of arching, and they can be planted to a depth three times the height of the bulb. Easter lilies can also be planted into Colorado gardens with varied success. Asiatic lilies are a popular perennial with large, impressive orange blooms, and can be planted in gardens or containers. Bulbs can be planted in a sunny area with well-drained soil after the last spring frost.

What temperature is too cold for lilies?

Lily exhibits optimal growth in a warm, sunny environment between 41-95 ℉ (5-35 ℃), although it can tolerate some shade in hotter climates. During the winter months, it is advisable to maintain a temperature above 41 ℉ (5 ℃) to prevent damage to the plant.

Do lilies grow well in Colorado?

True lilies are hardy and best planted in spring. There are two main types: Asiatics and Orientals. Asiatic lilies bloom in June and have little or no scent, while Oriental lilies, like the ‘Stargazer’, are highly fragrant and bloom in July and August. Lilies thrive in sun and well-drained soil, and should be grown in pots in heavy clay gardens or with critter problems, like voles. Use large plastic pots, fill half full with soil, and plant five or six bulbs, depending on the pot size.

Can water lilies survive winter?

As winter approaches, waterlilies prepare for the harsh winter by preparing for the colder months. Hardy lilies go dormant by late November, and they can survive the harshest winters without assistance. As long as the pond doesn’t freeze completely, the unfrozen water at the bottom protects the lily. When the lily starts growing in March or April, it’s time to repot it in fresh, fertilized soil for another season of lush blossoms.

Tropical waterlilies are tender perennials that can survive all but the harshest winters in zone 9. To prepare them for winter, stop fertilizing them in mid-October and encourage them to form small, hard, and durable tubers. When the plant is in full dormancy, remove the pot from the pond, rinse the soil off the roots, air dry the tubers, and store them in a glass jar or clear plastic bag filled with tap water.

Plant the tubers in the pond in mid-April for San Antonio, Dallas, or Fort Worth, and early to mid-May for west Texas. They will begin to sprout new leaves in 3-4 weeks. For an earlier bloom season, force the tubers to sprout in February inside an aquarium, set the heater to 70°F, and keep the grow light on for 12-14 hours per day.

The USDA Plant Hardiness Zone Map divides North America into 11 zones, each 10°F warmer or colder than the next. To determine your zone, visit the National Gardening Association’s website and enter your zip code. After flowering, avoid watering and let the plant die back. Cut foliage until it withers, allowing bulbs to store energy for winter. Lily bulbs don’t thrive in damp, soggy soil, so improve soil drainage to prevent rotting.

How do you winterize lilies?

Lilies in pots are more susceptible to colder temperatures than those in the ground, but they can be easily moved to a dry, protected area like a garage, basement, shed, or covered porch. Regularly check the soil moisture and water the soil lightly if the bulbs start to dry out. If keeping them outside, provide insulation with bubble wrap or straw to protect the soil and bulbs from freeze/thaw cycles. Lilies are perennials, meaning they can grow back each spring from their bulbs without needing replanting. However, proper care is necessary to keep them happy and healthy.

Can you grow water lilies in Colorado?

Water lilies are beneficial plants in sunny Colorado ponds, providing shade, shelter for fish, cooling the water, stabilizing temperature, and preventing algae growth. They also provide oxygen, use up nutrients in water that feeds algae, and block some sun. However, they can float if not anchored down, making cleaning the pond or separating plants more difficult. Lilies grow directly in gravel, but if not anchored down, they can float up, making it difficult to separate the plants.

Can calla lilies be left in the ground over winter?

Calla lilies are not cold hardy, so their winter care in warm climates is different from other gardens. If you live in USDA plant hardiness zone 8 or higher, your calla lilies can survive the winter outdoors in the ground without needing to be dug up. To do this, mulch the spot where they grow and stop watering for the winter, allowing the plant to go dormant and rejuvenate itself. If you find your calla lilies are not performing well in a warmer climate, store the calla lily rhizome for winter.

In colder climates, calla lilies will not survive the winter cold, so winter care will involve digging the rhizome of the plants. Digging them after frost has killed the foliage ensures that the calla lilies have stored all the nutrients they need to survive the winter. After digging, brush off any remaining dirt, leave the rhizomes to dry in a warm, dry place for four to seven days, or curing them. Store the calla lily rhizomes in a cool, dry place around 50 F.

(10 C.) and ensure proper winter care for these lovely flowers to keep them in your garden year after year. Sign up for the Gardening Know How newsletter today to receive a free download of our DIY eBook “Bring Your Garden Indoors: 13 DIY Projects For Fall And Winter”.
