Robust Milkweed

Robust milkweed is a butterfly magnet, attracting butterflies to the garden in droves. It is a low mounding perennial that blooms throughout the summer in borders of a country style or cottage garden. It performs best in a sunny spot.

Gayfeather Is a Garden Charmer

Gayfeather, Liatris spicata, is an interesting perennial that produces 1- to 3-foot-tall spikes of bright purplish pink or white flowers in late June to early fall. It is an ideal plant to grow in a butterfly garden.

Red Hot Poker

Drought- and heat-tolerant red hot poker plants are easy to grow. They will do well in mid summer heat, when other plants have wilted. The leaves are long, thin and dagger like. They produce flowered spikes from spring through fall.

Fair Foxglove

Foxglove is a vigorous perennial that bears elegant clusters of pure white flowers marked with purple or pale violet from early to late summer. It is easy to grow and cold hardy, plus it attracts bees, making it good for the cottage garden.

Purple Geranium

Purple geranium is a hardy geranium that has lots of gorgeous clear magenta purple flowers early in the season on a neat and very attractive mound of rich green foliage. Blooming often continues througout the summer in cooler areas.

Hatties Pincushion

Astrantias, or Hatties pincushion, are woodland perennials with showy, lobed, palmate leaves and colorful small flowers with delicate bracts. The flowers are useful for dried arrangements.

Yellow Button Flowers

Santolina chamaecyparissus, or lavender cotton, is a fine-textured, mound-forming shrub that has gray foliage and yellow button-like flowerheads formed by tubular flowers appearing in summer. Good for Mediterranean gardens and as edging.

Soft Shield Fern

The soft shield fern is an evergreen fern with arching, lance-shaped fronds. It will form large clumps in deep shade with lots of moisture.

Plantain Lily

Hostas, or plantain lilies, are popular because they give color and texture to perennial shade gardens from mid spring until mid fall. Large clumps of basal leaves produce lilylike flowers on tall stems. They are good for borders or edging.

Japanese Anemone

Japanese anemone is one of the best fall flowers. Its foliage is glossy and brilliant. Flowers are saucer shaped in single and fully double forms. They combine with other perennials in the border, and thrive best in slightly shaded areas.

'Pink Impression' Tulip

The lustrous petals of ‘Pink Impression’ tulip are a deep, rich rose at the center, shading to a delicate pale pink at the edge, while doing amazing things in between that include shades of melon to sunset.

Ornamental Onion

Allium giganteum, or ornamental onion, bears large rounded flower heads in summer that can reach up to 4 inches across. They produce a multitude of star shaped lilac pink flowers that attract butterflies. Grow in sun and well drained soil.
