Native to humid or wet North American lowlands and borders of deciduous forests and the most widespread of the native hollies. Glabrous, moderately glossy leaves.

Both male and female plants required for fruit set. Excellent massed, especially near water and large ponds. Can be grown directly in water, but does equally well in ordinary garden situations. Wild collected in Ontario.

ILLIAMNA rivularisAll Summer1906
Mountain Hollyhock120cm  Zone: 4
This native of western North America, from California to BC, is very lovely and garden worthy. The plant has a bush-like habit and very lovely pink saucer-shaped flowers over a long period in summer to fall. Notwithstanding its common name, the flowers, at least to my eye, resemble small pink single roses, more than hollyhocks. Interesting maple leaf foliage. Full sun to light shade. Thank you to Jesse Ritz, who wild collected this for us in the BC interior, at the most northern part of its range.

IPOMOPSISFamily: POLEMONIACEAE
24 species of perennials and biennials mostly native to North America.

IPOMOPSIS rubraSummer to Late Summer1932
Standing Cypress90-180cm  Zone: 4
Normally grown as a biennial, which perpetuates through self-sowing. Coral-red to salmon trumpets are spotted red and yellow inside, in a long, dense spike, a serious hummingbird attractor. Foliage is wonderful; soft, feathery and twirled. It is impossible to pass the plant without touching. We like to grow this tallish plant at the front of the border for its vertical affect, and also because it is light, airy, and skinny. One should plant a half dozen closely for an incredible show!
Germination Instructions: Easy, warm germinator.
