I want to write an article for children on wild flower
dormancy. We cleared several acres of mature alder trees, 40 to 60
years old, or more. After a few years, wild iris began appearing and
proliferated. Then came three Adder's Tongue (Pink/white.) These have
rhizomes. Seven years following the clearing, we counted 11 Turk's-cap
Lily plants (related to Tiger Lilies,) wild columbine and lupine. We
estimate roots and bulbs lie dormant under the crowding of the alders
for perhaps 40 years. This is on the Oregon Coast. Information on
dormancy is rare- at least this type of dormancy. Why don't roots and
bulbs decay after so long a time? I am researching other sources but any
help you can give is appreciated.
The following may be helpful:
