This St. John's Wort makes a superb filler for borders, even before the blooms appear! Eye-catching blue-green foliage forms a bushy semi-evergreen mound that is covered with golden yellow flowers from July through to September. The sunny blooms of Hypericum kalmianum 'Blue Velvet' are followed by prominent, conical red-tinged fruits that extend its season of interest well into autumn. A low maintenance, rounded shrub that is easy to grow and tolerates a wide range of growing conditions. Height and spread: 90cm (36").
Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.
