Jackson & Perkins Penstemon

This variety is hardy in zones 3 through 8, meaning it can withstand cold winters down to -40°F. If you live in a colder climate within this range, ensure the soil is well-drained to prevent root rot during the freeze-thaw cycle.

It requires full sun, which means at least six to eight hours of direct sunlight daily. While it is heat-tolerant, it will not bloom well or maintain its deep foliage color in partial shade.

Yes, its upright, clumping habit makes it an excellent candidate for containers. Just ensure your pot has adequate drainage holes and is large enough to accommodate its mature width of two feet.

Once established, 'Blackbeard' is quite drought-tolerant and prefers low water. You should only water it when the top inch or two of soil feels dry to the touch, as it dislikes sitting in soggy, waterlogged soil.

One of the best features of 'Blackbeard' is that its deep, eggplant-colored foliage remains dark and attractive throughout the entire growing season, not just during the bloom time.

It is a low-maintenance perennial that generally resists common garden pests. Because it is naturally heat and humidity tolerant, it requires very little intervention beyond basic watering and occasional cleanup of spent flower stems.
