Mountain Hollyhock
Iliamna rivularis
35 seeds
A member of the Malvaceae family, Mountain Hollyhock is a tall perennial of northwestern United States and western Canada resembling a hollyhock and having pink flowers. The plant typically grows 3-6 feet tall from a woody caudex and produces dense racemes of soft lavender-pink flowers. Plants blooms from June through August. They have 5-7 lobed, cordate leaves. Seeds have a very hard coat and can remain viable in the soil for more than 50 years. Seed germination is often triggered after a wildfire.
This species is native to sunny mountain stream banks, meadows, and open forest slopes from east of the Cascade Range, from British Columbia and Alberta, to Montana, and south to Oregon and Colorado.
Mountain Hollyhock also has the common name Kankakee Globe-Mallow. It has suffered drastic population declines largely from an altered fire regimen caused by long-term fire suppression which has changed the forest canopy structure. Shading limits plant growth and seed germination. Additionally, as mentioned above, the seeds germinate after scarification by fire.
To propagate, seeds are best scarified in a brief, 5-10 second hot water bath and immediately transferred to cold water to imbibe in water overnight. Seeds are placed in fine mesh bags in moist peat moss in ventilated containers in the coldest part of a refrigerator for a 30-60 days cold, moist stratification.
Sow seeds in prepared growing area in early spring. Seedlings emerge 7-10 days after sowing. Once established and thinned 2 weeks after emergence, the seedlings produce rapid shoot development.
