Double Japanese asters (Kalimeris pinnatifida) are not true asters. They bloom in summer unlike the more popular fall blooming asters (Symphyotrichum spp.). Essentially, the genus Kalimeris (from Asia) and Boltonia (U.S. native) are closely related and used interchangeably. ‘Pinnatifida’ is without question the best known cultivar. In August the plant is smothered with 1-inch diameter semi-double white daisy flowers […]

Panicle, PeeGee or PG hydrangeas (Hydrangea panculata) brighten up the July and August garden landscape. They’re native to China and Japan.

PG hydrangeas are vigorous growers with upright branching and coarse textured […]

Some plants deserve more respect. Over the years several U.S. native species have been tamed or domesticated. Yet, they retain their common name “weed”. Four popular former “weeds” are: butterfly weed (Asclepias tuberosa) ironweed (Vernonia lettermannii ‘Iron Butterfly’), sneezeweed (Helenium autumnale), and Joe-Pye weed (Eupatorium spp.). Butterfly weed (Asclepias tuberosa) […]

Here come the heucherellas (x Heucherella), also called “foamy bells”. Heucherellas are hybrids that result from crossing two U.S. native genera: foamflower (Tiarella spp.) and coral bell (Heuchera spp.).
