These flowers are hybrids of the famous St. John’s Wart. Their commercial value is in the ornamental fruits that follow the flowers. Hypericum features stems with sprays of berries and deep green foliage. It is quite hardy, but can exhibit damage due to poor growing or storage. Check fruits for any damage, particularly blackening or collapse of skin, as well as the leaves for yellowing or evidence of rust or leaf-miner. Hypericum that is fresh and in perfect condition may be held dry for several days. Processing for wet storage is straightforward, just cut stems and place the flowers in a low sugar holding solution. Hold in coolers.
