Plant of the Month

Text Box: Paper Bush
Edgeworthia papyrifera

   It’s the dead of winter, the color and cheer of the holidays are gone, and spring seems very far away.  This is a tough time of the year for gardeners.  The only consolation seems to be a warm fire and a stack of new seed or plant catalogues.  However, should you chance to wander into your yard one sunny but chill January day, wouldn’t it be perfect to find a bare-branched shrub coming into bloom with clusters of white and yellow flowers?  You’d be likely to visit again the next day and the day after that just to see how your hardy little winter blooms were progressing and eventually you’d be rewarded with not only a bloom but an intoxicating honey-citrus scent wafting across the garden.  And that’s what your paper bush is counting on, although it’s actually trying to attract a pollinator insect rather than an enchanted human. 

Rather than compete in the hurly-burly of pollination that is spring, paper bush has chosen to bloom in the winter when quite often it may be the only plant in bloom.  But there is risk to this plan, and the paper bush must compensate for it.  Even though there are no competitor plants, there are also very few polli-nators.  So how does a plant best attract those few that are out there?  Try a wonderful fragrance that floats across a far distance.  And it is this combination – lovely scent and unusual bloom period – that makes paper bush such a unique and valuable addition to the garden.

Paper bush is native to the moist mountain areas of China.  It is a relative of another winter bloomer with fragrance, daphne.  They can both be found in the family Thymelaeaceae.  Here are the pertinent cultural facts:
