Let’s face it, there are plenty of white and red flowering plant options for the garden, but if you look hard enough you can find some blue flowers as well. And no, I’m not talking about pansies. Try these three plants in your garden to make the festive feel of the 4th of July last throughout the season.

Blue Flowers of Campanula ‘Blue Clips’ Grow 6-9″ Tall

1. Campanula carpatica ‘Blue Clips’      Commonly referred to as Bellflower, Campanula provides a striking blue flower 3″ wide in the shape of a little bell. Campanula is hardy in zones 3-7 and prefers sun, though it is not tolerant of hot and dry conditions. Flowers appear from late spring through early summer. Blue Clips is a short cultivar growing only 6-9″ tall in a mounding form which makes it perfect for a spot front and center in the garden.

Caryopteris ‘Longwood Blue’ Blooms in Late Summer to Fall

2. Caryopteris x clandonensis ‘Longwood Blue’     Commonly referred to as Bluebeard or Blue Spirea, this shrub grows 2-3′ tall and wide boasting silvery leaves with spiky light blue flowers at the ends. Caryopteris is an herbaceous perennial hardy in zones 6-9 which can be cut back hard in winter. The blooms appear in late summer/ early fall which is a great feature since many other plants are finished blooming by the time Caryopteris takes center stage. Caryopteris will flower best in full sun but can tolerate partial shade.

The Flower of Hydrangea ‘Blue Lace Cap’ is Flat as Opposed to Globose like other H. macrophylla Cultivars

3. Hydrangea macrophylla ‘Blue Lace Cap’     Commonly called Lace Cap Hydrangea, I think this is an often forgotten Hydrangea which deserves a place in the landscape. The flowers are unlike most other H. macrophylla blooms in that they are very delicate, lacey and flat as opposed to globose. The blue flowers appear in July and August. Hydrangea m. ‘Blue Lace Cap’ is hardy to zone 5 and grows 3-5′ tall.

Amsonia (also known as Bluestar) is an underutilized native wildflower you should consider adding to your perennial beds. Two species widely found in retail nurseries and garden centers include Amsonia hubrichtii and Amsonia tabernaemontana. These species are very similar but the latter has wider leaves in addition to tongue-twisting binomial nomenclature.

Finely textured Amsonia foliage

Amsonia provides three seasons of interest in the garden. Clusters of small star-shaped flowers in shades of blue cover the plant in June. The blooms peak at a time in the season when many perennials are on a flowering hiatus. The bright green foliage lasts through summer and has a striking fine texture not commonly found on herbaceous perennials. Amsonia provides an additional season of interest with a glowing fall color. The vivid yellow-orange leaves are a highlight in the autumn landscape.

Fall foliage

Reaching a height and width of about 2-3 feet, Bluestar can easily find a home in the garden. It thrives in sunny locations and can tolerate poor soils and drought conditions. Bluestar will steal the show on its own, but a mass planting would be absolutely stunning.
