Plants that bloom in June in Zone 4 with green flowers

Coral Bells

Grown mostly for dramatic foliage, but the tiny bell flowers are a bonus.

Flowering Tobacco

Tubular flowers that release sweet fragrance at dusk. A cottage garden classic that attracts moths and hummingbirds.

Incrediball Hydrangea

Annabelle's bigger sibling with stronger stems that don't flop. Blooms the size of basketballs.

Japanese Painted Fern

Silver and burgundy fronds unlike any other fern. Foliage plant that earns its keep on color alone.

Karl Foerster Feather Reed Grass

Strong vertical plumes emerge in early summer and persist as tawny stems through winter.

Lady's Mantle

Chartreuse frothy flowers and pleated blue-green leaves that hold water droplets like mercury. The ultimate filler plant.

Ostrich Fern

Tall vase-shaped fronds that unfurl from fiddleheads in spring. Spreads to form dramatic colonies.

Rhubarb

Huge leaves and thick red stalks give a lush look while supplying tart harvests.

Tufted Hair Grass

Airy gold-green flower clouds hover above dark evergreen tufts. One of the few grasses that thrives in moist shade.
