Regional Highlights

Pacific Northwest

“Buy June‑blooming plants now to pick exact colors and varieties,” says designer Genevieve Schmidt. Monthly nursery visits let you evaluate seasonal gaps and coordinate a continuous show.

California

Matilija poppy (fried‑egg plant) steals the show with 9‑inch white, yellow‑centered flowers. Great for wild, dry hillsides — but spreads by suckers, so site carefully.

Southwest

June is the toughest month — hot, low humidity. “Ensure plants get enough water until summer rains arrive in July,” advises horticulturist Noelle Johnson.

Rocky Mountains

Prioritize planting schedules for edibles — many need specific days to maturity. Get on the grow‑your‑own bandwagon now.

Texas

Plan creative projects: compost bin, simple deck, water feature, or insect habitat. Insect habitats recycle dead wood, sticks, straw — great for kids to learn recycling and life cycles.

Central Plains

No hummingbirds? Moths pick up the slack. Bumblebee hummingbird moths love tubular blooms like ‘May Night’ salvia and penstemon.

Great Lakes

Shade garden still has blooms: goatsbeard, astilbe, masterwort, mophead hydrangeas (pink in alkaline soil; acidifier turns them blue).

Northeast

Peonies take center stage — lush, fragrant, perfect for bouquets. Invite neighbors to fill mason jars.

Mid‑Atlantic

“Save pruning until all baby birds have fledged,” says writer Amy Renea.

Southeast

Plant milkweed (Asclepias tuberosa) — sole host for monarchs. Expect it to be eaten to a nub; that’s success.
