As the seed nears the point of ripping it is very easily dislodged from the plant making it a rare find to collect ripe seeds from the old flowers. The use of some kind of drop cloth, like cheese cloth or old pantyhose might be helpful in collecting seed as they are dislodged. If you want to collect seed place the drop cloth down around the plants three or four weeks before the seeds ripen and collect them as the fall out of the flowers onto the drop cloth. Seeds should be sown as soon as collected and given a period of freezing. Or plant out in a pot over winter or in a seedbed.
Plants germinate in mid spring and grow fairly fast.
Flowering in their second or third year. Division should be done in spring or late summer and root cuttings taken in early summer propagate well. Below is listed some of the species. Leaves 7 - 13 inches long, green with out spots, lance shaped. Flowering stems come up erect and as flowering progresses they drop, when flowering is done and seed production begins stems may be flat with the ground or subsumed under the new foliage.
