Corylopsis spicata

Phonetic Spelling
kor-i-LOP-sis spih-KAH-tah
Description

Spike Winter Hazel can be bushy and open or upright with spreading picturesque branches. It prefers light, moist, but well-drained soil.

It performs best when located where it can receive some protection from the afternoon sun as well as high winds.  The recommended soil should be humus-rich, fertile, well drained, acidic with regular moisture.  A sheltered location will help protect this plant.  Although these are the optimum conditions, it may also do well in less desirable locations.  

It blooms on racemes in the early spring before the leaves unfold.  Plants have many racemes and each raceme has from 6 to 12 flowers.  

Pruning should be accomplished immediately  after flowering.

Insects, Diseases, and Other Plant Problems:  No serious insect or disease issues.  Protect from afternoon sun and high winds.  Late spring frost can damage the blooms.  Extreme heat will conditions require watering.

Differences between Corylopsis pauciflora and Corylopsis spicata:

  •      Flowers:  C. pauciflora - 2-3 per stem; C. spicata -  many flowers in one stem
  •      Stamen:  C. pauciflora - reddish ; C. spicata - yellow
