Widely known for disease resistance and garden performance, the All-America Selection Gold Medal-winning zinnia Profusion series has become an extremely popular variety in the United States. Now, there are two new colors in the series: ‘Profusion Apricot’ and ‘Profusion Fire’. Apricot is a light coral-colored flower with a terra cotta center. This will be a very popular item in both spring and fall pots, flower beds and planter boxes. Fire has a scarlet-orange flower, which offers a striking contrast against its dark green foliage.
Expect the same excellent garden performance from these two new colors, which also have the same cultural characteristics and production time as the other three colors of the series. Profusion is a dwarf variety with strong basal branching. It is best to sell in the green stage for high-density cell packs (36 cells or greater). For color sales, it is best to use larger containers like an 1801 or 4-inch pot. Peat-lite mixes work well at a soil pH of 5.5-6.5. Weekly applications of 200-250 ppm nitrogen using a well-balanced calcium nitrate-based fertilizer helps produce high-quality plants. Warm temperatures (above 75° F) can stretch the plants. It will take 6-7 weeks after transplanting to flower. Sakata Seed America. (408) 778-7758.
The Sweet series is the first professional cutflower dianthus series offered in vivid individual colors, but it can also be grown as bedding plants. No vernalization is required. It is first-year flowering and very uniform for height and flowering time field-grown plants reach 18-26 inches tall. There are large very fragrant, long-lasting blooms on tall, straight stems. Four colors make up the series: Coral, Purple, Red and White.
When grown as bedding plants, in plug production, 406-cell or larger trays are suggested. Use a well-drained, medium with a pH of 5.8-6.2, as well as good aeration and water-holding capacity. Temperatures should be maintained at 65-70° F. In finishing, Sweet is suitable for 4-inch or gallon production and can be grown pot tight. Temperatures should be kept at 60-72° F. After plants are established, apply a calcium-based fertilizer or 15-5-15 at 100 ppm 1-2 times a week. Sweet is very responsive to PGRs. Experiment with concentrations and application timing. A Bonzi spray at 20 ppm can be applied two weeks after transplant into a 4-inch or larger pot. For 6-inch pots or gallons, another Bonzi spray at 20 ppm may be required two weeks later.
