LATIN NAME: ERIGERON SPECIOSUS
COMMON NAME: Showy Fleabane
The showy fleabane flurries the clumping, upright perennial with the narrow, lance-shaped leaves and the loose clusters of the many-petalled, daisy-like flowers in the soft blues, the violets and the whites with the yellow centres that open through the summer, the blooms flurrying above the foliage in the long succession. The plant grows quickly into the bold clump, and it likes the sun, and the moist, well-drained soil.
Scientific Research & Plant Biotechnology
The many-petalled flowers of the showy fleabane give it a recognised place in the research on the meadow perennials of the daisy family, and the speciosus species appears in the studies of the long-summer bloom and the pollinator visits. The work looks at the way the blooms flurry above the foliage, the soft colour range, and the seed biology. The ecologists value the bee pasture, and the growers of the naturalistic border perennials keep the species in their catalogues.
Ecological & Economic Value & Wide Applications
In the sunny border and the wild garden, the showy fleabane flurries the summer border with the blue-white daisies. The flowers open for the bees and the butterflies, the daisies fill the vases, and the plant makes the bold, reliable clump. It grows well in the moist, well-drained, sunny ground. Blue-white, generous and pollinator-fed.
To grow the Showy Fleabane from seed, scatter the seeds over the surface of the fine, damp mix, then press them in, keep the tray in the cool, bright spot and mist lightly, and the seedlings appear within a couple of weeks.
Keep the tray in the cool, bright spot and mist lightly, and pot the seedlings on as they grow. The flurry blooms come within the season. Plant the young plants in the sunny, moist ground, and the flurry blooms will open through the summer.

LATIN NAME: Erigeron speciosus
COMMON NAMES: Oregon Fleabane, Showy Fleabane, Aspen Fleabane
Erigeron speciosus is a hardy clump‑forming perennial wildflower originating from mountain meadows and open woodland edges of western North America. Elongated soft‑green basal leaves create neat leafy rosettes, while upright branching stems carry narrower stem‑leaves. Large daisy‑like
flower heads rise above foliage throughout summer, featuring countless fine lavender‑blue or pale pink ray petals surrounding bright golden‑yellow central disks. The abundant blooms draw bees, butterflies and many local pollinator insects. After flowering, dry seed‑bearing achenes equipped with fine pappus bristles mature for wind‑driven natural dispersal. This adaptable perennial tolerates rocky slopes, average garden soils and seasonal dryness, widely used in pollinator‑focused borders, wild‑meadow plantings, hillside stabilisation and native‑species garden arrangements. Seed‑raised clumps establish reliably and preserve natural flower‑colour variation within seedling batches.
Growing Oregon fleabane from seed brings practical merits for landscape‑building projects. Seed‑raised plants build dense fibrous root mats that hold loose hillside and rocky topsoil securely. Broadcast sowing works well for large‑scale naturalised planting. Natural variation within seed lots brings pleasant differences in blossom shade and plant height among individual clumps.
Seed‑holding flower heads ripen through late summer once they fade to straw‑brown. Harvest mature capitula, then thresh and sift to separate tiny achenes from dry floral fragments and chaff. No cold stratification treatment is required for this species. Clean dried seed maintains good planting vigour under cool dry storage.
Mix the fine seed with light dry sand to achieve even distribution across porous, sharply draining flower‑seed starting substrate. Press seed gently onto the medium surface; minimal covering is needed, since light favours positive seed activation. Bright filtered light supports steady seedling development. Maintain gentle consistent surface moisture and strictly avoid water‑logged compost. Under favourable mild temperatures, numerous neat young seedlings emerge steadily.
Young seedlings produce simple narrow green leaves and build compact low rosettes. Careful thinning eliminates overcrowding and gives underground root systems room to spread. Young clumps transplant smoothly into individual containers or direct garden positions once several leaf pairs develop. Settled in sunny or lightly shaded sites with reliable drainage, these seed‑raised plants grow into free‑flowering vigorous clumps. Mature specimens produce long‑lasting summer‑time daisy‑like flower displays, feed local pollinator populations, and deliver low‑maintenance wild‑flower texture for temperate meadow‑style and pollinator‑garden layouts.
Native to Mexico, this perennial plant has established
itself in many Mediterranean areas and here in the UK too.
Grows to around 30 cm tall with a spread of around 60cm.
Pink daisy like DOUBLE flowers are produced
in as little as 3 months from sowing.
