GREAT INDIAN PLANTAIN Arnoglossum reniforme
Arnoglossum reniforme (great Indian plantain) is native to the central and east-central United States. Arnoglossum reniforme is a large plant growing up to 300 cm (120 inches or 10 feet) tall! Flower heads are numerous, usually white or pale green. The species grows in open, wooded areas.
Hardiness zones: 4-9
Seeds per pack: 30
Germination: As with many perennial seeds, these seeds require a period of moist cold to help them begin to 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 a sterile seed-start mix, and water. Place them in a clear plastic bag (to retain moisture), and in a refrigerator for 5-6 weeks. Once the cold period is completed, place the container back at room temperature for them to germinate. Be sure to keep the soil moist during this entire germination period. Seedlings will sprout several weeks after the warming period.
These seeds can also be planted in a cold frame outdoors in very early spring, while the temperatures are still cold and fluctuating, as long as you are able to keep the soil consistently moist. They will still need several weeks to germinate.
