It is of hybrid origin, but we cannot speak of its parents
with any certainty: one of them might be P.
dumosum, and the other related to P. maculatum. It is a
very free grower and an abundant bloomer; and, from
its numerous branches, it is always a bushy plant.
Although the flowers are produced only singly or in
pairs on the stem, yet their abundance makes up for
that deficiency. It thrives well in a mixture of turfy
loam, peat, and sand; and cuttings strike root readily,
if planted in pots in the same kind of soil, and placed
in a sheltered situation.
