Streambank Wild Hollyhock – Iliamna rivularis


iliamna rivularis flowers

This eye-catching, Idaho native is a member of the mallow family (Malvaceae). As its common name implies, it mainly occurs along stream banks and in wet meadows at elevations ranging from the foothills to subalpine zones. It varies in height depending on its location, but is typically between 3 to 6 feet tall. It sends up numerous flower stalks that are loosely populated with large pink to rose-purple (sometimes white) flowers. Its large lobed and toothed leaves resemble the leaves of maple trees or grape vines. The flowers, fruits, and seeds are similar in appearance to its cousin, hollyhock (Alcea sp.), which explains the other half of its common name. In the wild, forest fires encourage the seeds of Iliamna rivularis to germinate.

The western United States is lousy with penstemons. Idaho alone claims at least 43 native Penstemon species. Neighboring states claim similar numbers. It is hard to think of the West without them, which is why Idaho Botanical Garden has made it a point to showcase as many of these plants as we can get our hands on. We currently have around 60 different penstemon taxa (including varieties, subspecies, and cultivars) distributed throughout our gardens. In fact, a small handful of these penstemons are part of a nationally accredited collection through American Public Garden Association’s Plant Collection Network.
