sweet-scented yellow flowers, blooming from April to November. _J.
revolùtum_ is the earliest flowering one, and of the same colour; it is
apt to grow straggling, and should be close pruned as soon as done
blooming, which will be about June. _J. grandiflòrum_ is frequently
called Catalonian, and should be pruned early in spring to make it bloom
well, especially old plants. _J. officinàle_ is a hardy climbing plant

reported there is a double one.
