Upcoming WPPC Events

2021 Walks on the Wild Side Schedule is Released!

Garden Walks:  We’ve scheduled a complete line-up of native plant garden walks in 2021.  From mature woodlands to newly landscaped yards to nature preserves, there’s something for everyone in our 2021 schedule.  There will be a total of seven walks this year between April and September.  These are excellent opportunities to see how beautiful our native Midwestern plants are, and to get ideas on how to incorporate them into your own yard.  Update:  The location of the walk for May 16 has been changed.  The walk will now take place at the property of Chris and Paul Rechten and will be offered on both May 15 and May 16.  Walks are scheduled both days at 1pm and 3pm for a total of four possibilities.  This yard stands out for for the emphasis that the owners have placed on horticulture and propagation.  It features many unusual plants including several species of Trillium and Orchids.

Plant Sale:  We made the difficult decision to cancel our 2021 plant sale after losing access to our venue.  We will be back with a wide variety of high-quality native plants for sale on May 1, 2022.  Look to us for natives for your wetland, woodland or prairie garden.

WPPC Volunteers:  Recently a group of WPPC volunteers traveled to Glacier Park to help the McHenry County Conservation District plant and cage several species of small trees and shrubs that were purchased with funds donated by the WPPC.  Our members participate in many volunteer activities in the Chicago area including native plant presentations and education, habitat restoration and rare plant monitoring.  Contact us if you’d like information on volunteering with our programs or with other conservation organizations in the area.

Evening Primrose is a biennial Illinois native plant that can be up to 7 feet tall but is usually around 4 feet. there is usually a central stem with alternate leaves but sometimes can have multiple stems having a bush-like appearance.  The light or olive green leaves are up to 8″ long and 2″ wide. The flowers can be about 4″ wide and open in early evening and last until the next morning usually done before noon. On cloudy day they can last longer. Flowers have a lemony scent and bloom from mid-summer into fall.

The plant prefers full sun, average moisture and sandy soil but will tolerate other growing conditions often found in disturbed areas. The plant forms a stubby rosette during the first year, but becomes tall during the second year when it flowers, sets seeds and then dies.
