Illiamna

Illiamna remota ( Kankakee Mallow )
A perennial, reaching up to 6 feet. It is critically endangered in the wild where it is found in Kankakee County in northern Illinois. It is found on alluvial river plains in the wild.
The 5 to 7 lobed, Maple-like leaves are up to 7 x 6 inches in size. The foliage is mid-green above, downy gray-green beneath.
The pale pink flowers, up to 2.5 inches wide, appear during early to mid summer.
Hardy zones 4 to 7 in full sun to partial shade on light, well drained soil. It is tolerant of temporary flooding. It is also very tolerant of hot humid summers. Seeds can remain viable for up to 50 years and may require some pretreatment to germinate any time soon. It is unfortunately prone to grazing by deer but otherwise easy to grow.

Illiamna rivularis ( Mountain Hollyhock )
A deep taprooted, slow spreading, stoloniferous+ shrubby perennial, reaching up to 6 x 6 feet in size, that is native to prairies and mountain meadows in the western U.S. ( from near Kamloops, British Columbia to Vernon, B.C. to Cranbrook, B.C. to far southeast Alberta; south to southeast Oregon to northern Nevada to Colorado ).
The Maple-like leaves are 5 or 7 lobed. The mid-green foliage turns to golden-yellow during autumn.
The bright pink flowers, up to 2 inches wide, are borne on showy dense spikes.
Hardy zones 4 to 8 in full sun to partial shade on moist, humus-rich, neutral, well drained soil. It is not drought tolerant. It is resistant to rust, unlike related Hollyhock.
