McDowell falls and PNW native plants

  1. 1. McDowell Falls & the Plants That Live There{ Linda R. McMahan, Ph.D. Community Horticulture Oregon State University Extension Service
  2. 2. Most people come to picnic and play near the taller falls near theThe Waterfalls western, lower parking lot.
  3. 3. My personal favorite is the more secluded falls near the upper, more eastern parking lot, accessible from a steep but well-The Waterfalls maintained trail with overlooks.
  4. 4. What really draws me to this special place are the plants, growinglush in the moisture created from the stream and waterfalls—the mistlingers in this canyon at the western edge of the Cascade Mountains.The Plants
  5. 5. Against the backdrop of the stream, an overhanging branch of vinemaple becomes dynamic, never once the same.Vine Maple, Acer circinnatum
  6. 6. The black veins and stems of the maidenhair fern stand out againstthe green background. This moisture loving plant is common alongthe stream banks.Maidenhair fern, Adiantum pedatum
  7. 7. The nearly constant moisture fosters the growth of decomposingfungi, these on a fallen log surrounded by sword fern.Sword fern, Polystichum munitum
  8. 8. Flowers of thimbleberry attract bees and other flying insects forpollination. The raspberry-like berries will be medium red.Thimbleberry, Rubus parviflorus
  9. 9. Wild bleeding heart is still blooming in late May, but beginning to setits seed pods that seem to grow right out of the flower. The seeds aredisseminated by ants. The pollinator is a native butterfly.Wild bleeding heart, Dicentra formosa
  10. 10. Our native wild blackberries remind me of the taste of honey.Notice the bluish white stem, one way to tell them from the invasiveintroduced blackberries.Wild blackberry, Rubus ursinus
  11. 11. Named after Fort Vancouver, this elegant and popular groundcover isplentiful in the park. It is deciduous, having bright yellow fall color.Inside-out flower, Vancouveria hexandra
  12. 12. The false solomon’s seal was in full bloom, creating graceful archesagainst the tall straight trunks of Douglas fir.False soloman’s seal, Smilacina racemosa
  13. 13. The small surprises keep me coming back to see more. Each day,there is something new. Today, it was this emerging bloom of theWestern trumpet honeysuckle, Lonicera ciliosa, one of our few nativevines.Visit yourself, and see what is bloomingnow.
