BOTTLE GENTIAN Gentiana andrewsii
Bottle Gentian blooms look like large buds, waiting to burst open. Opening only slightly, blooms are deep blue and large. Mature plants will self-seed, creating a colony. This plant can be grown in regular soil, or slightly boggy soils. Flowers have long stems, and are extremely beautiful as cut flowers and in arrangements!
Type: Hardy perennial
Location: Part sun or part
Hardiness zones: 3-7
Bloom time: Spring and early summer
Seeds per pack: 30
Germination: As with many perennial seeds, these seeds benefit from a period of moist cold to help them grow. 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 4-6 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.
