This
shrub is also known as the Easter Rose and it seems to
be in bloom every year at Easter time. Mature shrubs can be large
(6 x 4) with arching branches. The growth is twiggy and airy -
it is not a dense shrub. There are two varieties - one has pom-pom
type flowers and the other has single flowers (the double 'Pleniflora'
is shown at the right). One of the outstanding characteristics
of this shrub is that it will bloom in heavy shade. Another nice
feature is the branches stay green during the winter. It is very
easy to grow and does not require any special conditions. It is
outstanding in a shrub border or against a dark colored house.
The kerria is a great choice for a difficult shady spot which
calls for a large shrub.
