How to grow Fritillaria:
Family: Liliaceae
The genus, Fritillaria consists of almost 100 species. All of these are found in the northern hemisphere, with the main habitats being the areas around the Mediterranean. Only a limited number are being cultivated, but interest in this genus is very much on the rise.
Fritillaria Assyriaca:
Family: Liliaceae
Syn.: F. canaliculata
Flower colour: brownish purple
Flowering period: April-May
Average plant height: 35 cm
Planting depth to base of bulb: 15 cm
Spacing between bulbs: 20 cm
Light requirements: full sun
Landscape uses: rock gardens, perennialising in wet areas
This species is found in Eastern Turkey and Western Iran.
Fritillaria imperialis:
Family: Liliaceae
Popular name: Crown imperial
Flower colour: yellow, orange-red and red
Flowering period: April-May
Average plant height: 100 cm
Planting depth to base of bulb: 20 cm
Spacing between bulbs: 30 cm
Light requirements: full sun to partial shade (some shade is particularly important in warmer climatic zones)
Landscape uses: perennial beds and borders
This is by far the most well-known species. It is also one of the earliest plants to be cultivated. Clusius introduced this majestic plant to the Netherlands as early as the 16th century. Illustrations of it date back to 1610! The plant is found in such locations as Turkey, Iran and Afghanistan.
Plant these large, unpleasantly scented bulbs as early in the season as possible, and immediately after acquiring them. This is necessary because the roots will start developing inside the packaging, and this can result in damage during planting. The soil must drain quickly and thoroughly; heavy soil will definitely need the addition of extra sand. Specimens that receive what they need often continue to flower year after year in the same location, especially in climatic zones 4 - 6. Sometimes, however, a stem emerges but fails to bloom. In that case, plant new bulbs in another location, preferably among ground cover plants. The flowers have a distinctive musk-like odour and contain large drops of nectar.
Most significant cultivars:
'Aurora': orange-red
'Lutea': bright yellow
'Lutea Maxima': yellow
'Rubra': deep vermilion red
'Rubra Maxima': very large deep vermilion-red flowers
'The Premier': orange-red
Fritillaria Meleagris:
Fritillaria meleagris does not much resemble F. imperialis. This species is native to Europe where its bulbs usually grow in very moist locations.
For better growing conditions, soil can be improved by adding upgraded black peat. The best results are achieved when the plants are not disturbed. To provide an ideal situation, sphagnum peat can be introduced between the plants. Doing so allows the seeds to germinate as well. These fritillarias are usually sold as mixed colours but certain specialists offer cultivars. The white cultivar known as 'Alba' is especially lovely.
Fritillaria Michailovskyi:
Family: Liliaceae
Flower colour: reddish-purple with yellow edge
Flowering period: April-May
Average plant height: 20 cm
Planting depth to base of bulb: 15 cm
Spacing between bulbs: 15 cm
Light requirements: full sun or partial shade
Landscape uses: excellent for shaded rock gardens, as a pot plant (also offered this way commercially) This species with its stunning colour combination comes from Northeastern Turkey.
Fritillarie Persica:
Family: Liliaceae
Popular name: Persia
Flower colour: deep purple
Flowering period: April-May
Average plant height: 75 cm
Planting depth to base of bulb: 20 cm
Spacing between bulbs: 25 cm
Light requirements: full sun
Landscape uses: perennial beds and borders
This species places the same demands on soil and habitat as the much more well-known F. imperialis. Planting both species next to one another is especially lovely when the partner is a yellow F. imperialis. Late-flowering yellow or white narcissi also make good neighbours. The bell-shaped flowers of F. persica are found on tall, rather spindly stems. To be assured of a yearly flowering it is best to lift the bulbs in July and store them in a warm (20°C) location and then replant them.
Fritillaria Pontica:
Family: Liliaceae
Flower color: greenish with brown and orange spots
Flowering period: April-May
Average plant height: 20-40 cm
Planting depth to base of bulb: 12.5 cm
Spacing between bulbs: 10 cm
Light requirements: full or partial shade
Landscape uses: rock gardens, and under trees and shrubs
This is an unique, little-known species native to Asia Minor and Southeast Europe. It's uniquely colored flowers have an unpleasant odor.
