Quick Overview

ORIENTAL TRUMPET LILY, Altari

FULL SUN The Oriental Trumpet Lilies are some of the giants of the home flower garden. Some plants can reach heights in excess of 6 feet. From towering flower stems cascades of often fragrant blossoms fall. A flower stem can have as many as 20 blossoms per stem. Altari is a stunning Oriental Trumpet which produces 20+, 4-inch diameter, broad petaled blossoms per stem. Each petal has a background of sterling white that is covered with raspberry feathering. At the center of the feathering is a broad, deep raspberry feather. This lily inspires joy in even the most negative person.

Lilies must have well drained soil and prefer an acid soil. They should not be lifted each year because they can tolerate deep cold and frost conditions. They should be planted 8-10 inches deep as soon as the soil can be worked in the spring.

Bloom Time: Early to Mid-Summer
Hardiness Zone: 3-9

Oriental Trumpet Lily, Altari

The lilium genus, surprisingly, is only indigenous to the temperate zones of the Northern Hemisphere, but it has been so popular for so many centuries that it is worldwide in distribution. There are many, many species native to North America, Asia and Europe. Flowers are of many different sizes and shapes – some highly fragrant, some not. Lilies were a part of the Greek and Roman civilizations. New World lilies and the lilies of China and Japan were quickly and eagerly embraced by Europeans and the British.

Since the Renaissance, the development and cultivation of lily cultivars has proliferated, but it was not until the late 1800s that the most significant lily introductions were created. E. H. Wilson (1876-1931), the Director of The Arnold Arboretum outside of Boston, MA introduced L. davidii, L. regale, and L. sargentiae. These three lily species became the most important lilies of the 20th century.

Asiatic and Oriental lilies are often very similar in appearance and many astute and experienced gardeners see no difference in the two. However, there are differences and these can be substantial. Oriental lily plants grow taller than Asiatics. The flowers can be heavily fragrant and are usually much larger than the Asiatic blossoms. Orientals bloom much later than Asiatics so it is best to plant both Asiatics and Orientals for continuous blooms from early summer to fall.

Oriental lilies can be planted in the fall or the spring. If planting in the fall make sure the location does not become soaking wet in the winter or the bulbs will rot. Lilies can be planted in the spring as soon as the ground can be worked and up until mid-June. Lilies planted after mid-June may not bloom the first year. Plant the bulbs in organically rich soil amended with bone meal. Keep the soil moist, but do not allow the bulbs to stand in water. Plant the bulbs 6 inches apart and at least 6 inches deep. In Hardiness Zones 1-4, planting the bulbs 8 inches deep is recommended. Twice a year, mix some coffee grounds (1/4-1/2 cup) into the surface soil around the plants. Lilies like a slightly acid soil and the coffee grounds will help.

Planting Lilies in Containers

Lilies LOVE being grown in containers, but the containers must be deep – at least 10-12 inches. Use the soil mix described in detail in our Harvesting History YouTube video. Do not use prepared soil mixes.

The Best Soil Mix for Containers

Briefly the soil mix is 60% topsoil, 20% peat moss and 20% compost or dehydrated cow manure. You can plant according to the following chart:

Type 10-12 inch 14 inch 18 inch
Asiatics 3 Bulbs 5 Bulbs 10 Bulbs
Orientals 2-3 Bulbs 3-5 Bulbs 6-8 Bulbs
Oriental Trumpets Tigrinums 2 Bulbs 3 Bulbs 4 Bulbs

Plant the bulbs 8 inches deep. Dust the hole with ¼ cup bone meal per bulb. Cover the bulbs with 8 inches of soil. Water heavily, but do not allow the pots to stand in water. Once the lilies have emerged from the soil, fertilize every two weeks with blossom booster fertilizer.

In the fall, when the top growth has died completely back, remove the dead growth and dust the surface of the soil with bone meal. Mulch with 2 inches of compost, if possible, or a mix of peat moss and dehydrated cow manure-5 parts peat moss to 1 part manure.

Make sure you water your lilies throughout the summer. Do not allow the pots to dry out.
