Garden Layout

Type: In-ground bed, approximately 10ร—20 ft Orientation: Tall species on north side so they don’t shade shorter plants Soil: Amend with compost at planting. Most species prefer average to lean soil โ€” don’t over-fertilize natives.

Moisture placement:

  • Marsh marigold and jewelweed on the downhill/wet edge where water collects
  • Bloodroot and wild blue phlox on the north side where tall plants cast afternoon shade (woodland edge species)
  • Everything else in full sun

Irrigation: Netafim Techline CV at 12" spacing, surface under mulch. Most native perennials need irrigation only during establishment (first 1-2 seasons), then can be disconnected.

Seed Collection Guide

When to collect: Wait until seed heads are fully dry and brown on the plant. Seeds should be hard and dark. If you can shake the head and hear rattling, they’re ready.

How to collect: Cut the entire seed head with 6" of stem. Place upside down in a paper bag. Label with species name and date. Let dry for 1-2 weeks in a cool, dry place.

Storage: Clean seeds by rubbing dried heads over a screen or into a bowl. Store in labeled paper envelopes (not plastic โ€” moisture causes mold). Keep in a cool, dry, dark place. Most native seeds remain viable 2-5 years.

Cold stratification: Many native Ohio species need 60-90 days of cold/moist treatment before germination. Species requiring stratification: golden alexanders, wild columbine, bloodroot, blue false indigo, rattlesnake master, butterfly weed. Method: mix seeds with damp sand in a zip bag, refrigerate Dec-Feb, sow in spring.

Self-sowing species (minimal effort): Black-eyed Susan, partridge pea, jewelweed, wild columbine, blanket flower. These will naturalize on their own once established.
