Key plants in the Oregon Garden

Dainty white flowerheads that look like lacework are born in summer and seem to hover in a frothy haze above the finely cut, green foliage. The flowers are often used by florists to add a ethereal, romantic feel to bouquets, and they can last up to 10 days after being cut. This annual also looks a delight in the garden, and has quite an architectural feel. Once the flowers have faded and the seeds have ripened, they will attract finches to the garden.
 

An upright, stout-stemmed, branching perennial to 1.2m tall, with rough-textured, deeply divided, pinnate leaves. From summer to autumn it bears long-stemmed, daisy-like flower heads to 12cm across, with bright yellow, drooping ray florets around a prominent red-brown cone.

 

Small, plum-coloured, button-like flowers with wiry, upright stems, seem to hover above the neat mounds of blue-green, pinnate foliage. This cultivar is more tolerant of drier conditions, so is particularly well-suited to mixed or herbaceous borders.

Clump-forming perennial about 60-90cm tall, with hairy stems and deeply-lobed mid-green foliage. The saucer-shaped, white, blue or violet flowers are 4.5cm across and appear in early to mid-summer.
