Corylopsis pauciflora
Medium · Some experienceAbout Buttercup Winterhazel
Buttercup Winter Hazel is a delicate deciduous shrub from Japan and Taiwan, growing 4-6 feet tall with a spreading, layered habit. In very early spring—often before forsythia—it produces pendulous clusters of 2-3 fragrant primrose-yellow bell-shaped flowers along bare branches. The emerging leaves are tinged bronze-pink, maturing to soft green. One of the earliest and most refined spring-flowering shrubs, it brings a quiet elegance to woodland edges and partly shaded borders.

History
Corylopsis pauciflora occurs naturally in the mountains of central and western Honshu, Shikoku, and Taiwan, typically as an understory shrub in cool deciduous forests. German botanists Philipp Franz von Siebold and Joseph Gerhard Zuccarini described the species in 1835 in Flora Japonica. The epithet pauciflora, meaning few-flowered, refers to its relatively short inflorescences (usually 2-5 flowers per cluster) compared to the many-flowered spikes of other Corylopsis species.
The genus name Corylopsis means resembling Corylus (hazelnut)—the relationship is to the leaf and catkin shape, not a close botanical tie. Along with Hamamelis (witch hazel), the winter hazels are among the earliest shrubs to flower, opening in late February through April depending on climate. The primrose-yellow tubular bell flowers dangle in short chains before the leaves emerge, emitting a soft honeyed-cowslip fragrance.
The species was introduced to Western cultivation around 1862 via Siebold's nursery and is the most compact of the winter hazels (to 1.5 meters), suited to smaller woodland gardens. Native to mountain forests of Japan and Taiwan. The genus name Corylopsis means 'hazel-like', referring to the similarity of its leaves to those of hazel (Corylus). The 'pauciflora' (few-flowered) species is the most dainty and refined member of its genus, with the fewest flowers per cluster but perhaps the most garden-worthy proportions. Introduced to Western cultivation in 1862 from Japan.
