An Asiatic lily is a lily in the genus Lilium.

Plants in this genus are sometimes referred to as “true lilies,” reflecting the fact that they are botanically classified as lilies, rather than just being called “lilies” by people who are not knowledgeable about horticulture.

True lilies are bulbs, and they have fleshy stems, blade-like leaves, and trumpet shaped flowers. The Asiatic lily is among the easiest to grow.

Asiatic lilies are hybridized lilies which are famous for their vigor. Given an area which gets sun for at least half the day and some well drained soil, these lilies will flourish with minimal effort on the part of the gardener.

They typically return in very thick clumps each year, requiring thinning every three to four years to break up the bulbs and spread them out so that they will not crowd each other in the soil.

Bulbs can be planted either in the early fall or mid-spring, and the plants will produce flowers in summer. A range of colors are available, including orange, white, red, and yellow, and some blooms are variegated, with colors like red and white or orange and yellow.

They tend to do best when planted in large beds and clumps, so that they have an opportunity to sprawl, and some cultivars may need to be staked as they grow to support the blooms.

The Asiatic lily can also be grown in large containers, for gardeners who do not have a lot of room to work with.

Asiatic lilies make splendid cut flowers, and they are also very appealing to butterflies, making them a great addition to a butterfly garden.

Caring for Asiatic lilies includes mulching in the fall and leaving the mulch on until after the last frost has passed, and trimming away dead foliage as the plants die off in the fall. These plants also benefit from being fertilized in the spring to stimulate growth.

Many garden suppliers sell Asiatic lily bulbs, especially around the time of year when they should be planted. The bulbs do not go fully dormant, so they should be planted as soon as possible. Seedlings can also be planted, in lieu of bulbs.
