Best plants for Indiana
These species reliably perform in Indiana's climate — a blend of regionally-adapted ornamentals and native plants that don't need babying once established. Start with this short list, then expand once you know your specific microclimate (slope, shade, drainage).
Native plants of Indiana
Natives evolved alongside Indiana's soils, pollinators, and weather patterns, so they need almost no supplemental water or fertilizer once established. Mixing 30-50% natives into a garden dramatically improves its drought resilience and its value to local birds and pollinators.
- Tulip poplar (Liriodendron tulipifera, state tree)
- Eastern redbud
- Wild lupine
- Prairie dropseed
- Pawpaw

Frost dates and timing in Indiana
Average last spring frost: mid-April (south) to early May (north). Average first fall frost: early October (north) to late October (south). Growing season runs about 160-200 days. As always, average dates are starting points — set seedlings out a week or two later than the average last-frost for high-value crops like tomatoes and peppers, and have row cover or frost blankets ready for an unseasonable late freeze.
Use the fall planting schedule by zone to plan your second crop, and the vegetable garden planting schedule for week-by-week spring timing.
Soils and amendment in Indiana
Glacial-till loams in the north and central, alluvial soils along the Wabash and Ohio rivers, and loess in the southwest.
Challenges specific to Indiana
Heavy summer thunderstorms and hail, Japanese beetles, and poorly-drained clay subsoils that need raised beds in low-lying areas.
For drought-prone parts of Indiana, see the drought-tolerant garden design guide. If your yard sits low and stays wet, the drainage fix without regrading guide covers raised beds, French drains, and bog-tolerant planting palettes.
