Description
There’s none other like it.
- F1 hybrid uniformity and vigor partnered with high levels of disease resistance build a premium package not found in other trailing vinca. Screened against 36 contemporary strains of aerial Phytophthora, including ten of the most virulent that cause Phytophthora blight on annual vinca.1
- Large, high-quality flowers completely cover plants creating blankets of color lasting all season long.
- Perfect for use in premium hanging baskets and landscape applications in harsh conditions.
- 1 Confirmed in collaboration with Clemson University; these isolates were found at grower facilities and in landscapes across the southern U.S.

XDR Disease Resistance
XDR: Cora® Cascade XDR vinca is screened against 36 contemporary strains of Phytophthora nicotianae, including ten of the most virulent that cause Phytophthora blight on annual vinca, confirmed in collaboration with Clemson University and in independent trials across North America. However, they are not immune to the disease. For this reason, we highly recommend chemical rotations as a responsible and critical part of a disease resistance maintenance program. Applications are also advised to control several other diseases that can infect vinca, such as Thielaviopsis, Rhizopus, Rhizoctonia, Pythium and Tospovirus (INSV and TSWV).
Germination
Germination time: 7–8 days
Media temperature: 76–78 °F (24–25 °C)
Chamber: Optional
Light: Not required for germination
Seed cover: Yes
Seeds per cell: 1
Moisture level: 5 - SATURATED: Soil is dark brown and shiny, free water is present at the surface of the soil, water drips freely from the bottom of the tray, and trays are heavy with a visible bend in the middle.
Young Plant Production
Recommended tray size: 288-cell tray
Temperature
Day: 74–76 °F (23–24 °C)
Night: 74–76 °F (23–24 °C)
Average daily temperature: 74–76 °F (23–24 °C)
Lighting
Day extension lighting: Not necessary
Light intensity: 2,000–3,000 foot candles (400–500 micro mols)
Day length response: Day neutral
Daily light integral (DLI): 14–16 mols/day
Media pH: 5.5–5.9
Media EC: SME EC: 0.9–1.3 mS/cm
Fertilizer: 75–125 ppm N
Moisture level: Media should be allowed to dry between irrigations. Alternate between moisture level 3 and 4. 3 - MOIST: Soil is brown in color, strongly squeezing the soil will extract a few drops of water, and trays are light with no visible bend. 4 - WET: Soil is dark brown but not shiny, no free water is seen at the surface of the soil, when pressed or squeezed water drips easily, and trays are heavy with a visible bend in the middle.
Pinching: No
Plant growth regulators (PGRs): Usually not needed in propagation; under low light levels B-Nine® WSG may be sprayed at 1,500–2,500 ppm. Do not use Bonzi® to avoid potential phytotoxicity.
Plug grow time: 5 weeks in a 288-cell tray
Tech tip: Soil temperatures lower than 75 °F (23 °C) during germination may decrease germination rates. Keeping media pH at 5.8 or lower will help reduce the likelihood of Thielaviopsis infections.
Finishing
Temperature
Day: 76–78 °F (24–26 °C)
Night: 64–66 °F (18–19 °C)
Average daily temperature: 70 °F (21 °C)
Lighting
Day extension lighting: Not necessary
Light intensity: 6,000–8,000 foot candles
Day length response: Day neutral
Daily light integral (DLI): Greater than 18 mols/day
Transplanting: Transplant directly into the finished container. Place the rooting media slightly below the level of media in the container. Make sure that the root ball is covered and that the cutting is situated in the center of the pot.
Media pH: 5.5–5.9
Media EC: SME EC: 1.5–2.1 mS/cm, PourThru EC: 2.3–3.2 mS/cm
Fertilizer: 125–175 ppm N
Pinching: No. Pinching is not recommended or needed.
Plant growth regulators (PGRs): If needed sprays of B-Nine® WSG at 2,500–5,000 ppm or A-Rest® at 2–4 ppm may be applied.
Tech tip: Start with a disinfected growing area and keep media pH below 5.8 to help avoid Thielaviopsis infections. Cora Cascade's disease resistance is targeted to aerial Phytophthera which is a serious landscape disease in southern climates. It may have higher resistance to other diseases but is still susceptible to Thielaviopsis. Control Thrips to prevent INSV or TSWV infections. Do not try to finish Vinca early in the North since the plants need high light and warm temperatures to grow adequately. PGRs are usually not required except in pack production. Never apply Bonzi® to Vinca since leaf spotting may occur.
Moisture level: Media should be allowed to dry between irrigations. Alternate between moisture level 2 and 4. 2 - MEDIUM: Soil is light brown in color, no water can be extracted from soil, and soil will crumble apart. 4 - WET: Soil is dark brown but not shiny, no free water is seen at the surface of the soil, when pressed or squeezed water drips easily, and trays are heavy with a visible bend in the middle.
Common pests: Thrips, Fungus gnats, Shore flies
Common diseases: Thielaviopsis, Rhizopus, Rhizoctonia, Pythium, Tospovirus (INSV and TSWV)
Postharvest: Try Chrysal Alesco®, a postharvest foliar spray, to protect ethylene sensitive crops during shipping and retail
Scheduling

Grower Success Guide
Look for our flowers in garden centers across the country. Many of our seeds are available to consumers from seed packet companies online.
Growers, retailers, agencies, and brokers - can access images through the Trinity Image Library. The library link is conveniently located in the footer of every page.
Yes, during transport, plants experience a lot of stress and when plants are stressed they can release ethylene. Higher temperatures, enclosed spaces, and damage to the plants increase the ethylene concentrations in the shipping environment.
