Landscape Attributes
Blues Festival® St. John’s Wort is a multi-stemmed deciduous shrub with a ground-hugging habit of growth. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.

This is a relatively low maintenance shrub, and should only be pruned after flowering to avoid removing any of the current season’s flowers. It is a good choice for attracting bees to your yard, but is not particularly attractive to deer who tend to leave it alone in favor of tastier treats. It has no significant negative characteristics.

Planting & Growing
Blues Festival® St. John’s Wort will grow to be about 3 feet tall at maturity, with a spread of 3 feet. It tends to fill out right to the ground and therefore doesn’t necessarily require facer plants in front. It grows at a slow rate, and under ideal conditions can be expected to live for approximately 20 years.

This shrub does best in full sun to partial shade. It prefers to grow in average to dry locations, and dislikes excessive moisture. It is considered to be drought-tolerant, and thus makes an ideal choice for a low-water garden or xeriscape application. It is not particular as to soil type or pH, and is able to handle environmental salt. It is highly tolerant of urban pollution and will even thrive in inner city environments. This is a selection of a native North American species.

Blues Festival® St. John’s Wort makes a fine choice for the outdoor landscape, but it is also well-suited for use in outdoor pots and containers. Because of its spreading habit of growth, it is ideally suited for use as a ‘spiller’ in the ‘spiller-thriller-filler’ container combination; plant it near the edges where it can spill gracefully over the pot. It is even sizeable enough that it can be grown alone in a suitable container. Note that when grown in a container, it may not perform exactly as indicated on the tag – this is to be expected. Also note that when growing plants in outdoor containers and baskets, they may require more frequent waterings than they would in the yard or garden.

Want more info on sizes?
IndyPlants sells landscape size plant material. These often come in black nursery containers and are classified in sizes such as #2, #3, #5, etc. This correlates to the volume of the container, 2 gallon, 3, gallon, 5 gallon, etc. The bigger the number, the larger the pot, and the larger the plant. You’ll also see larger sizes such as 2” BB, 2.5” BB, 3” BB, etc. This stands for ‘Balled & Burlapped’. These plants are usually much larger and are not transported in black nursery pots. The sizing correlates to the diameter of the trunk of the tree.
