Cinquefoil is a popular plant in gardens of various sizes and is often found in city parks and arboretums. They have several flower colours and thanks to zero maintenance they can be planted almost anywhere.
Description of the plant:
White flowering cinquefoil McKay’s White was discovered by an employee of McKay’s Nursery in Waterloo, Wisconsin, USA, as a sport of an older cinquefoil variety Katherine Dykes. It features almost snow-white, 2.5-3 cm wide, single, 5-petalled flowers. The plant tolerates summer heat which results in continuous production of flowers from June until September. It grows fast into a dense and well-branched shrubs about one meter tall and wide in just 5 years. Palmately divided leaves are small, medium green, not very showy but handsome. Pruning is possible in early spring. Thanks to very little care needed and high resistance to whims of weather, pests, and diseases it is ideal for low maintenance gardens.
Cinquefoil grows best in well-drained, poor, or moderately fertile soil in full sun. Fast and large growing varieties can be trimmed in early spring. It does not need extra fertilizing or watering once established, though a good selective fertilizer may enhance continuous production of new flower buds. It is fully hardy to abt. -40°C (USDA zone 3), and suitable for outdoor pots down to zone 5, just do not let them dry out completely.
