  • 10. Examples of Gardens with Native Plants<br />Lady fern at the Connie Hanson Garden, Lincoln City<br />Athyriumfilix-femina is delicate, can grow tall in ideal conditions, but is deciduous and requires wet habitat<br />

  • 12. B&B native plant garden in the Cascade Mountains<br />Native sedums in whimsical pots-at least 4 sedums are native to Oregon<br />
  • 13. B&B, Cascade Mountains<br />Sword fern, rock, and an old tree trunk<br />
  • 14. B&B, Cascade Mountains<br />Oxalis oreganaand Piggy-back plant (Tolmiea menziesii) mixed groundcover<br />
  • 15. Private garden, Portland Oregon<br />Stream plant, Darmerapeltatum used in a garden setting<br />
  • 16. Private Garden, Portland, OR<br />Emerging false hellebore (Veratrumcalifornicum) growing through decomposing ash leaves<br />
  • 17. Private Garden, Portland, Oregon<br />Salal (Gaultheria shallon) and sword fern on a decaying stump<br />

  • 23. Ask yourself: Why do we garden the way we do?<br />We copy what we see and remember: family, friends, neighbors<br />Our gardening traditions are from England<br />Today, we are seeing new ways to garden (restoration for example)and we copy that too, <br />Connie Hanson Garden, Lincoln City, Oregon<br />
  • 24. History Lesson on Native Plant Gardening<br />The Victorian Era in the British Isles<br />Formal gardens of London’s Crystal Palace and the informal lines of a William Robinson landscape Photos: Wikipedia<br />
  • 25. The Wild Gardening Tradition<br />In the 1890’s, Scottish gardener William Robinson reacted to Victorian “excess” by promoting Wild Gardening—note this was gardening in a naturalistic style, not necessarily with native plants <br />Robinson’s house and garden: Wikipedia<br />
  • 26. One of Robinson’s colleagues promoted new styles that led to border gardens<br />Gertrude Jekyll (1843-1932 popularized the idea of the informal border in many publications and garden designs. The “natural” style caught on and remains popular today. <br />A modern “border garden”<br />
  • 27. Experimented widely with southeast native plants, including Osage orange as a hedge, at his Monticello home<br />Sponsored Lewis and Clark Expedition<br />Thomas Jefferson<br />(1743-1826)<br />Photos: Wikipedia<br />

  • 29. Essentially, two styles of gardening with native plants have evolved side by side <br />Substituting natives for traditional plants and developing “garden-worthy” cultivars<br />Gardening with native plants for their own sake in naturalistic landscapes<br />VS<br />Photos: left azalea and sword fern (Polystichummunitum); <br />right coltsfoot (Petasitesfrigidus)<br />
  • 30. Another thing -- growing native plants in Oregon is very recent!<br />Only in the past 15 to 20 years in Oregon and perhaps 30 or more years in the US, have we explicitly created native plant gardens <br />Mixed succulents in a private garden, including Sedum spathulifolium, center <br />
  • 31. Adding Native to Existing Garden – An easy way begin<br /><ul><li>Match conditions of the plants to those of your garden—sun/shade, water use, soil characteristics
  • 32. Start first with well-known natives, such as sword fern and red flowering currant, or established cultivars
  • 33. Choose colorful flowers or foliage, complementing features, and a “tame” habit before you explore other species
  • 34. Look for wildlife value—birds, bees, food and shelter</li></li></ul><li>Some Favorite Plants<br />Sedum spathlufolium<br />Vancouveriahexandra<br />
  • 35. Oregon grape, our state flower<br />Berberis (Mahonia) aquifolium, likes full sun, can be easily pruned, attracts pollinators and birds, easy to find<br />
  • 36. Sedum spathulifolium<br />Best native sedum, easy for containers or well-drained soil, available at many retail nurseries<br />
  • 37. Heuchera‘Palace Purple’<br />A cultivar of Heucheramicrantha, readily available, moist, rich, and well-drained soil<br />
  • 38. Mock orange<br />Philadelphuslewesii, available at native plant nurseries and SWCD sales. Fragrant and easy—sun to part shade, moderate water<br />
  • 39. Camas (Camassia)<br />Available as a bulb in better garden centers, needs wet winters and dry summers—no problem for us!<br />
  • 40. Wild Strawberry<br />Fragariachiloensis, coast or dune strawberry, and other species--vigorous ground-cover, sun/part shade, bees and birds, easily available<br />
  • 41. Epilobiumcanum(Zauschneriacalifornicum)<br />California fuchsia, full-sun, spreads slowly, attracts hummingbirds, fall bloomer<br />
  • 42. Vancouveriahexandra<br />Shade-loving deciduous groundcover, duck-foot plant<br />
  • 43. Vine Maple<br />Acer circinatum, best in part shade, some have good fall color, bird-friendly <br />
  • 44. Stream Violet<br />Viola glabella, accent or groundcover, drought tolerant, butterfly host plant<br />
  • 45. Red Twig Dogwood<br />Cornussericia, wet or dry, large, prune from the base, berries attract birds<br />
  • 46. Red Flowering Currant<br />Ribes sanguineum, February/March bloomer attracts hummingbirds, also bees. Blue/black berries are edible and a bird favorite, many cultivars available<br />
  • 47. Check out the recommended requirements for each species<br />Provide water to establish, even if the species is drought-hardy<br />Refrain from too much fertilizer-plants are usually adapted to our typical soils<br />Cultural Requirements<br />Douglas iris and Viola adunca<br />
  • 48. Leave enough space—some natives may grow larger than anticipated<br />Many can be hedged, but some gardeners prefer the natural forms<br />Prune multi-stemmed shrubs from the base<br />Cultural Requirements<br />Desert Parsely and snowberry<br />
  • 49. Don’t assume plants are “deer-proof”<br />If you want plants to self-seed or provide berries for wildlife, don’t dead-head the flowers<br />Cultural Requirements<br />Ocean spray and osoberry<br />
