I
am not sure why Shakespeare had his “primrose path” lead to “dalliance”,
but a primrose path is certainly a colorful way to lead a visitor to
your door. The most characteristic primrose color is yellow, but there
are many other colors available. All the species have cheerful spring
blooming flowers and most are easy to grow. Some have evergreen leaves
and some will rebloom a little in fall. The most commonly sold primroses
are hybrids of Primula x Polyantha; these come in just about any color
you can name and several of them bicolored. Moreover the :candelabra”
types, which include Japanese primrose (P.japonica), have clusters of
pink, purple or white flowers atop stems as tall as two feet, and they
bloom in late spring.
Japanese
star primrose (P.sieboldii) is shorter in rosy shades. It is hardy and
The Barnhaven strain is particularly vigorous. If you want to grow
“Primrose” then you should prefer part shade and humusy, moisture
retentive soil. The candelabra types like the soil to be wet. None of
them do well in very hot climate. The species can be grown from seed;
hybrids are propagated easily by division. Division also renews vigor.
Do it right after they have finished blooming, at least every other
year. Source: Charismatic Planet
