TIGER LILY Lilium superbum
Lilium superbum, also known as Turk's cap lily, turban lily, swamp lily, lily royal, or American tiger lily, grows from 4–7 feet (1.2–2.13 m) high with typically three to seven blooms, but exceptional specimens have been observed with up to 40 flowers on each stem. It is capable of growing in wet conditions. It is fairly variable in size, form, and color. The color is known to range from a deep yellow to orange to a reddish-orange "flame" coloring with reddish petal tips. The flowers have a green star at their center that can be used to distinguish L. superbum from the Asiatic "tigerlilies" that frequently escape from cultivation..
Type: Hardy perennial
Height: 1.2-2.1m, 4-7 feet!
Location: Sun or part
Hardiness zones: 4-8
Seeds per pack: 3
Germination: Requires cold stratification. See germination information below.
Note: This plant species is known to have toxicity. Ingestion of these seeds or this plant can cause illness such as vomiting or diarrhea.
Germination: As with many perennial seeds, these seeds require a period of moist cold to help them break dormancy. This is done by giving them a cold 'winter' period (artificial or natural), and then a warming to simulate 'spring', and time to grow! Here's how this can be done:
Obtain a planting container that has holes in the bottom for excess water to drain. Place the seeds just under the surface of your growing medium, and water. Place your container in a cold area (but not freezing, perhaps a refrigerator) for 6 weeks. Once the cold period is completed, place the container at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout a few weeks, or occasionally several months, after the warming period.
If you are planting your seeds in late winter or spring, these seeds can be planted outdoors while it is still cool out (once the ground is workable and unfrozen), to receive the cold period naturally in the garden.
