Overview

Why Na * tive Plants?

  • Propagation by Seed
  • – Identifying, Collecting, Storing, Treating, Sowing
  • Propagation by Cutting
  • – Hardwood Cutting, Softwood Cutting, Root Cutting, Layering

Why?

  • * Unordered List ItemBeauty
  • Food and Habitat for pollinators and wildlife
  • Genetic resource
  • Decrease water use
  • Storm-water management
  • Decrease maintenance
  • Hold soil in place
  • Increase soil microbiology
  • sequester Carbon

Seeds – Identification

Seeds – Collection

  • Your own yard, or with permission
  • Allow seeds to mature
  • Collect in envelopes
  • Label: Plant name, Date, Place
  • Mature Seed Heads
  • Seeds – Storage and Treatment
  • Seeds should be fully mature and dry
  • Consider how they propagate in nature
  • – Spring or Fall seeds
  • Store in refrigerator or freezer, or cool basement
  • Stratification – 30-90 days cold treatment (wet or dry)
  • Scarification – breaking seed-coat – acid or abrasion
  • Prairiemoon database
  • Seeds – Sowing
  • Sow outside in winter – seeds will stratify naturally.
  • Sow thickly in the pot – you can separate once they germinate (full packet in 4” pot)
  • Label each pot with plant name and date
  • Keep watered once they sprout
  • Or sow indoors….
  • Seeds – Transplant
  • Transplant sprouts to separate pots – grow out for a
  • few months – Grow Native seedling ID
  • Transplant sprouts directly to garden beds
  • Most wildflowers won’t flower in the first year
  • May want to plant with annuals
  • Sleep – Creep – Leap
  • Cutting – Hardwood
  • Take 1 year wood in the fall
  • Pencil thickness
  • 4-6 nodes
  • Cut top diagonally
  • Put in soil or medium over winter
  • Cutting – Softwood
  • Take during active growing season
  • 3-6 inches, 4-6 nodes
  • Strip leaves from lower part, trim upper leaves
  • Keep humidity up: spray or tent
  • Indirect lighting
  • Rooting hormone can help
  • Most will root in 2-4 weeks
  • Cutting – Root
  • Collect in late winter (label)
  • Pencil width is good
  • One or two nodes
  • 4-6 inches
  • Plant in pots and allow to leaf out
  • Plant in beds and mark clearly
  • Cutting – Layering
  • Simple layering: bend a stem down to the ground and pin it there until it roots
  • Air-layering: Place a ball of soil around a growing stem,
  • keep soil moist, cut from plant when roots are showing through.
  • Cutting – Division
