A larger upright-rounded selection with showy deep yellow flowers from June into fall and fine textured dusty green foliage; the ultimate flowering shrub for northern gardens, hardy, tough and adaptable to all conditions, but dislikes wet soils
Jackman Potentilla has yellow flowers at the ends of the branches from late spring to early fall. It has bluish-green foliage throughout the season. The small ferny compound leaves do not develop any appreciable fall colour. The fruit is not ornamentally significant.
Jackman Potentilla is a dense multi-stemmed deciduous shrub with a more or less rounded form. Its relatively fine texture sets it apart from other landscape plants with less refined foliage.
This is a relatively low maintenance shrub, and is best pruned in late winter once the threat of extreme cold has passed. It is a good choice for attracting butterflies 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.
Jackman Potentilla is recommended for the following landscape applications;
Planting & Growing
Jackman Potentilla will grow to be about 4 feet tall at maturity, with a spread of 4 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 30 years.
This shrub does best in full sun to partial shade. It is very adaptable to both dry and moist locations, and should do just fine under average home landscape conditions. It is considered to be drought-tolerant, and thus makes an ideal choice for xeriscaping or the moisture-conserving landscape. It is not particular as to soil type or pH. 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.
