RHS Award of Garden Merit® Plants

The Royal Horticulture Society's Award of Garden Merit goes only to plants that meet a minimum of the following requirements: "excellent for ordinary use in appropriate conditions, available( at nurseries and garden centers ), of good constitution, essentially stable in form and colour, and reasonably resistant to pests and diseases". The AGM list is updated periodically to ensure that these are still the best of the best. "Awards are only made after assessment by an RHS forum of experts appointed by the Society to assess that particular trial. Each forum has its own area of expertise, and draws upon the experience of a wide range of experts, including nurserymen, specialist growers and well-known horticulturists. This assessment must then be ratified by the relevant Plant Committee. The trial and assessments usually take place at one of the four RHS Gardens but can also take place at one of our partner gardens, National Trust gardens or commercial nurseries." For more information and to see all of the RHS AGM winners visit https://www.rhs.org.uk/plants/trials-awards/award-of-garden-merit.

American Gold Rush Black-Eyed Susan, Rudbeckia, Coneflower

Rudbeckia 'American Gold Rush' PP28498

A 2020 All American Selections Herbaceous Perennial award winner! 2-3" wide dark-eyed golden yellow daisies are produced throughout the summer and even into fall atop a dense and compact well-branched plant. American Gold Rush Rudbeckia was selected with disease resistance in mind as well as this plant's ability to flower throughout summer and a compact habit. It may be most similar to and is considered to be a hybrid of Rudbeckia fulgida var. deamii, or the Brown-Eyed Susan, which can reach 3' in height. Like its parent, expect this hardy clump forming perennial to revel in the heat and sun of summer with its disk flowers providing nectar for smaller pollinators and the ripened seeds of fall and winter are sure to attract songbirds. Provide American Gold Rush Rudbeckia with a full to mostly sunny site in an average moist, well-drained soil for optimum vigor and flowering. Add this easy to grow perennial to the garden and landscape but it is also compact and free-flowering enough to provide a summer long show as a container plant.

Blackhawks Big Bluestem, Turkey Foot Grass

Andropogon gerardii 'Blackhawks'

One of the hottest new native grasses on the market! Blackhawks Big Bluestem starts off in spring as a deep green clump of upright to arching blades that may be tipped with red to purple. It is in late summer when the real show begins with the upright and arching foliage and flowering stems of August deepen to red to red-purple and further deepening and intensifying as the cooler fall weather arrives becoming nearly all black as its sturdy and showy flowering stems begin to mature. Blackhawks Big Bluestem is a slightly more compact plant reaching about 4-5' high when in flower. The species is native throughout much of the eastern 2/3's of the US and is a clumping to slowly spreading rhizomatous grass whose seeds are utilized by a number of seed eating birds. Provide a full to mostly sunny site with an average to well-drained, acidic soil for the deepest foliage colors and optimum vigor. Plants are in their best form when grown in a low fertility soil. Overly fertile soils can cause them to topple at maturity. Images courtesy of Brent Horvath, Intrinsic Perennials, all rights reserved. Item# 12169

Outdoor Light: Full sun, Mostly sunny, *Part shade, *Part sun

Blaumeise is considered by many to be one of the best of the Lacecap Hydrangeas producing very large flower clusters that are surrounded by some of the most deeply colored and themselves very large, showy sterile florets. In acidic soils the flowers are a deep royal blue and in alkaline soils the flowers are a dark rosy red. The foliage is large and shiny and is held on stout sturdy stems. The only drawback for this amazing Hydrangea cultivar is that it has limited cold hardiness and is will probably be best grown in zones 8 and warmer. An eastern or partially shaded southern exposure might be optimum even then. Item# 10731.
