Choice perennials for this July

July is a time when herbaceous perennials are the star performers in the garden. We have put together a list of must-haves for the summer border, containers and hanging baskets.

Clematis ‘Bijou’ is a new variety of patio clematis which only grows to a 30cm, this looks wonderful in a hanging basket with its large purple-blue flowers appearing from June to August. It also makes fantastic groundcover at the front of a border. Grow in full sun or dappled shade and cut back to the lowest pair of buds in early spring.

Geum ‘Totally Tangerine’ (as seen in the photo above) is the best geum for flower power, flowering from May to the first frosts. It forms a large clump, reaching a height of 90cm and a spread of 60cm. The apricot-orange flowers of this Chelsea favourite work perfectly with strong, deep-purple tones, so grow with Salvia ‘Caradonna’ or Veronica ‘Royal Candles’.

Verbena ‘Bampton’ is a recent introduction and looks fantastic in both naturalistic planting schemes with grasses and in a container on the patio. It has deep purple foliage and stems and then delicate, violet-blue flowers from July until October. This variety grows to 90cm in height and has a spread of 60cm. It needs full sun and does well in a hot, dry situation.

Salvia ‘Caradonna’ is arguably one of the hardiest and best salvias for its deep blue-purple flowers over compact, grey-green foliage from June until October. This plant is great for a sunny spot, is drought-tolerant once established and will attract bees and butterflies into your garden. 

Rudbeckia Summerina is a new series which are an intergeneric cross between a perennial Echinacea and an annual Rudbeckia.  These plants have a bushy habit, are great for bees and are reliably hardy and perennial. They come in shades of orange, yellow and brown and have a long flowering time, from mid-June through until the first frosts.
