Hypericum pyramidatum - Great St John's Wort

This listing is for 100 seeds of this perennial cottage garden favourite.

Also known as Hypericum ascyron (and known in europe by this name), this is the North American variety, which has been renamed to avoid confusion and to distinguish it from its close relative. Known locally either as Giant or Great St John's Wort, it earns this name as it is by far the largest species in the genus of almost 500 species. It grows up to 2 metres tall and produces large yellow flowers over a few weeks in summer. Ideal for use in a cottage garden or informal setting where it adds height to the back of any plantings. It is relatively pest free and the flowers attract polinating insects to the garden.

Hardy in Zones 4 to 10, it is easy to grow from seed and will quickly establish itself. It does require a 60 day stratification period so can either be sown outdoors in the autumn, or sown in pots and then subjected to cold weather (either in a frame or in the fridge) before the warmer spring weather encourages germination. Full instructions for growing all US wildflowers can be found at this link.
