Hypericum prolificum – This wonderful St. Johnswort species produces masses of small deep yellow St. Johnswort flowers for a very long period in summer. What the flowers lack in size the shrub more than makes up in number, hence “prolificum”. This shrubby St. Johnswort is a bee magnet, abuzz with many species for all the many weeks it is in bloom. The warm brown exfoliating wood which remains attractive in winter supports multitudes of 3-sided seed capsules. These supply winter interest or may be cut and used in dried arrangements. We have ours planted with Spiraea x bumalda ‘Neon Flash’ and the two make a strong summer coupling. For gardeners towards the northern end of its range spring planting is advised.
