Wildflower Collection

  • NEW in 2013

  • Easy to grow

Establishing your own wildflower meadow couldn’t be easier with this diverse collection of wildflower plug plants. A wildflower patch in your garden makes a lovely informal display that needs little maintenance. You'll be amazed at the beneficial insects and birds they attract, many of which will act as pollinators and natural pest control for your garden! Try sprinkling some wildflower seed between these plug plants - they will all knit nicely together. The perennial varieties will come back year after year whilst the annuals will happily self seed and reappear in a new position each year. Height: 150cm (59"). Spread: 50cm (20").

Knautia arvensis

Field Scabious, Wildflower
Glorious scabious-like, pin cushion blooms are borne on the lax stems of this wildflower, in soft shades of lilac-blue.

Teasel

Dipsacus fullonum, Dipsacus sylvestris, Wildflower
A tall, striking native biennial, known for its large prickly seed heads which persist well into winter on roadside verges, waste ground and field edges. The lilac-pink conical flower heads are borne above serrated leaves in mid to late summer, attracting lots of bees, butterflies and other beneficial insects. The seed heads are also a good source of food for birds. Teasels are an excellent architectural plant for the back of garden borders or in wildlife gardens where they will self-seed freely for a continual display. Dried teasel flowers also make an attractive and textural addition to cut flower arrangements. Height: 1.5m (5’). Spread: 45cm (18"). More info
