38. Choosing Native Plants for Your Garden Look for:

  • Ornamental Value
  • Sentimental Value
  • Plants from Close By
  • If you want show, go for it

39. Oregon is All About Rain

  • The western 1/3 has lots of it, except for the summer months
  • The coast and coast range have even more, sometimes arriving as seasonal storms
  • Central and Eastern Oregon have limited precipitation, falling mostly as winter snow or in storm events, and often drains away quickly

40. Understand Wild Habitats

  • Coastal habitats are often extremely wet and plants need extra water to survive
  • An exception are those of sand dunes which can be very hardy

41. Understanding Wild Habitats

  • Western mountain forests are wet and shady
  • Plants from these habitats sometimes need extra water and shade Oxalis, bleeding heart, Piggy-back plant, and more

42. Understanding Wild Habitats

  • Willamette Value Prairie habitats and other prairie sites in Oregon have some good garden plants that are often drought tolerant and colorful, Examples are lupine, Oregon sunshine, Penstemon serrulatus, Sidalceas, and yarrow

43. Understanding Wild Habitats

  • As we go east, the land becomes dryer, as in the Columbia River Gorge Catherine Creek here
  • Plants require good drainage and the more delicate ones sometimesdo not do well in gardens, sedums, the Oregon form of California poppy

44. Understand Wild Habitats

  • Central Oregon conifer forests are also dry, plants require good drainage, but can often withstand both heat and cold, many penstemons, desert parsley, eriogonum

45. Understand Wild Habitats

  • The Eastern Oregon is wildly beauty with drought tolerant desert natives, some of which are extremely adaptable to the rest of Oregon like the golden currant.


  • Oregon Flora Project 47. Care of Native PlantsReally there is no mystery!

  • Appropriate Water Use
  • Soils and Fertilizers
  • Pruning

48. Appropriate Water Use

  • Oregon natives are adapted to periods of summer dry, and some require this to survive
  • You may need to adjust irrigation if natives are planted with other more water-needy plants
  • In some cases, the plants will look better in a cultivated setting if they receive more water than falls in your area, especially if the plants are away from their natural habitat.

49. Soils and Fertilizer

  • Use the native soil if possible
  • Increase of decrease drainage as appropriate for the plants you are using
  • Use minimal if any fertilizer--the plants may actually grow too tall!

50. Pruning

  • The style is up to you:
  • Can be dramatic
  • Can be subtle
  • Can be non-existent
  • In all cases, prune appropriately for the plants structure

51. My 10 All-Time Favorites
