AestheticsWhat are your favorite colors/combinations, and your
least favorite colors/combinations?Consider: a plant may have a beautiful flower, but it
also needs to have good foliageWhen do you want the show?Are you stuck on the idea of perfection?
creating your plant list…ScienceKnow your site: dry and wet areas, sun and shade,
compacted soil; soil test!!Put sun plants in the sun and shade plants in the
shadeCold and heat hardiness issuesBottom Line: performs well in Ohio weather and soil,
and can be tolerant of less than optimal conditions
creating your plant list…
where do plants live?
woodland: upland, bottomland, vernal pools
prairie/meadow: dry, wet, mesic
aquatic: lakes, rivers
wetland: swamps, marshes, bogs, fens, vernal pools
edges: the boundary of two habitats
PracticalPurpose of the garden?Maintenance considerations: dividing, staking,
fertilizing, pruning, weeding, watering….Native vs. non-native issue? Invasive/non-
invasive issue!! “plays well with others”Has other redeeming qualities beyond its beautyAppeals to youBudget
creating your plant list…
the cultivar conundrum
often the basis of plant selectionbiodiversityappropriate for habitat?appropriate for pollinators?find the balance
