Green Fuse Botanicals introduced the Salvia nemorosa Sensation series, including Deep Blue, Deep Rose, Sky Blue and White. Bred by Florensis, the compact plants reach a height and width of about 12 inches. Plants flower the first year without vernalization, although cold temperatures are beneficial. Cosmic Evolution is an addition to the Big Bang coreopsis series from Skagit Gardens. It produces large creamy-white flowers with magenta striping, which is more predominant in cooler temperatures. Bred by Darrell Probst, the plants are hardy to Zone 5 and possibly Zone 4. The well-branched plants reach a height of 30 inches and spread of 24 inches. They flower from June through October. They can be used in landscape beds, borders and large containers. They also make excellent fresh cut flowers. Hydrangea macrophylla Passion (‘RIE 4’) from PlantHaven has a sturdy upright growth habit and produces soft pink double blooms from summer through fall. For pink flowers, treat with superphosphate and maintain a pH of 6.0-6.2 to prevent aluminum uptake. For deep blue flowers, treat with aluminum sulfate and maintain a pH of 5.2-5.5. It has deciduous, glossy dark foliage. It is best grown in partial shade and moist soils. Passion can be used as an indoor and outdoor pot plant, as a specimen plant and in landscape plantings. From a 4-inch liner, a 2-gallon container finishes in 12 months. Florist de Kwakel has introduced additions (Vivian, Romy, Valeria and Linsey) to its Garvinea hardy perennial gerbera, which are available from Northern Innovators. Outdoors the plants’ small flowers provide a tremendous amount of color until winter. The strong plants with compact foliage can take cold temperatures. Hardy in Zone 7. Bright Bicolor is the newest addition to PanAmerican Seed’s F1 Mesa gaillardia series. Yellow, which was released in 2010, was an All-America Selection and Fleuroselect Gold Medal winner. Its clean seed makes for easier and faster sowing. These first year flowering plants produce red flowers with a bright yellow band. The band width varies depending on environmental conditions. The well-branched upright plants do not flop over and fill in a gallon container quickly.
