Goldsmith Varieties Bloom In Beijing

Goldsmith Varieties Bloom In Beijing

The Water Cube, where Michael Phelps won a record eight gold medals, was the place to be at the Olympics in Beijing, China. Those who visited the Water Cube were treated to a blanket of color in the form of two vinca varieties from Goldsmith Seeds–’Cora Deep Lavender’ and ‘Cora White’–that thrived in the extreme tropical heat and high humidity.

Over three years, Beijing Flowers & Trees Corporation–the company responsible for the landscape during the Olympics–organized flower trials that included dozens of varieties from around the world. Cora, Sparkler and other Goldsmith varieties were among those that won out. ‘Sparkler Blush’ and ‘Sparkler White’ were planted in a bed outside the Bird’s Nest National Stadium.

Here are some growing tips for growing Cora vinca from bedding plant consultant David Koranski:

– Provide a well-aerated media: Finish plants in areas with protection from seasonal rains, and adequate dry back will occur in 18 to 24 hours.

– Maintain an EC range of 1.2 to 2.0 to finish plants: An EC less than 1.2 will stress plants and may cause susceptibility to disease. An EC greater than 2.0 in a dry substrate for longer than four to eight could result in iron-deficient plants with stunted roots and shoots.

– A slow release fertilizer can be added: Plants treated with slow-release fertilizers should not be allowed to dry down. Dry down could result in iron-deficient plants with stunted roots and shoots.

– Provide a pH no greater than 5.5: With a pH greater than 5.5, vinca may become susceptible to Thielaviopsis, creating and environment for secondary infections such as Phytophthora and Pythium.

– Monitor pH weekly: Vinca can raise the pH of the growing substrate by as much as one unit in 10 to 14 days. If Thielaviopsis is prevalent in your greenhouse, treat plants with a preventative fungicide during the first seven days after transplant.

– Grow vinca in soil temperatures no less than 70°F (21°C) day and night: An average daily temperature of 80°F (26.7°C) is optimum.

– Grow vinca in humidity of 40 to 70 percent: If growing in greenhouses, avoid foliage diseases such as Botrytis and Rhizopus with horizontal fans to lower humidity.

– Review and employ methods to eliminate Thielaviopsis:  First, employ a pH of 5.5. Second, if this disease has infected your greenhouse, maintain an EC of less than 1.5. Third, use preventative fungicide following label directions.

– Use a reputable plant lab to diagnose problems so an effective treatment plan can be applied.

– Only use new plug trays and finish containers.

Other varieties displayed at the Olympics were PrimeTime petunias, Xtreme impatiens, La Bella snapdragons, Super Parfait dianthus, Antigua marigolds, Kiss gazanias, Asti osteospermums, Duchess torenias, Frost petunias, Ramblin trailing petunia, Magellan zinnias and Swizzle zinnias.

California Spring Trials 2016 visitors to Syngenta Flowers found the breeder company and its employees happy and excited for the future, in the wake of the announcement of its acquisition by ChemChina. Now Syngenta Flowers is ready to move forward with its breeding efforts in geraniums, pentas, and other crops, and it is opening its perennials offerings to the whole supply chain for a better chance to get those plants to retail.     Syngenta Wants To Revolutionize Geranium Breeding The big news in this year’s trial, says Karl Trellinger, Technical Services Representative at Syngenta, is the change in Syngenta’s breeding efforts in geraniums and pentas. The Calliope geranium series, long considered a premium line in the market, is getting a makeover. Growers have told the breeder that they love the colors available in the Calliope series, but the plants are just too vigorous for smaller containers and combinations. As […]

Golden State Bulb Company Shows Off New Concepts In Cal…

There’s no question that Golden State Bulb Company’s specialty is in breeding virtually any color of Calla Lily, available in about any habit — cut flower, bouquet pot, upright pot type — the list goes on. But now, the bulb specialist is focusing on making calla lilies more accessible to the masses, for use in combination planters and the landscape, with calla six-packs. Calla breeder Peter Beckman showed us the shrunken-down version of these beauties, and they’re certainly perfect for patio pots, planting along paths or at the front of the garden, or en masse for an elegant statement. This presentation makes it easy for consumers to pick up and use callas, without the intimidation they might feel from a bulb crop, says Dr. Allan Armitage.   They’re also versatile for growers to plant in early to mid-February to add to finished containers in the spring, or to sell in […]

Floricultura-Pacifica in Salinas opened its doors to invite California Spring Trials visitors to experience new offerings from European breeders including Westhoff Flowers, Beekenkamp, and PAC-Elsner, as well as California native The Plug Connection. While there, it was interesting to witness the ongoing and highly automated production of orchids, as well as construction of more greenhouse space happening simultaneously. As is tradition, Westhoff Flowers invited its visitors to flag their favorite combos at the entrance, and showed off its unique assortment of annuals, as well as a few concepts. The breeder is working loosely with Florist Holland to show mixes used with Westhoff Flowers — or Westflowers — annuals and Florist gerberas in the center. The combinations are bright and cheerful, and spur a happy reaction in those who have seen them, so it will be interesting to see what happens with this concept going forward. Another new idea is putting together […]
