Catharanthus Soiree Double is a garden vinca typically grown as an annual, though it is a tender perennial in zones 10-11. This hybrid produced by Suntory offers superior branching, better vigor, and more abundant flowering even in high heat. Soiree Double White blooms from spring to fall, maintaining its compact, mounding habit with dark, glossy foliage covered in 1.5-2-inch white flowers. This plant is easy to care for and makes a stunning hanging basket or mixed container. Pair with Double Pink and Double Orchid for a mixed container that will add flair to any front porch.
Soiree Double White Selling Tips
Sell Soiree Double White to customers who are looking for easy-to-care-for flowering containers or baskets. The abundant, long-lasting blooms and compact, dark foliage create a hanging basket that will turn any porch into a summer haven. Soiree Double blooms from spring through fall with good vigor and maintains a compact, mounding habit of 10-14" tall and 20-25" wide.

1. Put containers in full sun. In landscape applications, plant 4-inch containers in well-drained soil in full sun 20-25 inches apart.

General Growing Tips For Your Rooted Cutting Liner
For best results with Soiree Double White, use well-drained soil in full sun with a pH of 5.8-6.2, EC of 1.0-2.0, and moderate feed (200 ppm nitrogen). Plant 1 rooted liner per 4-inch or 6-inch container, 2 per gallon container, and 3 per 10-inch basket. Watch for whiteflies, aphids, and thrips. Soiree Double White is easy to care for and, even in extreme heat, requires little more than regular water.
Flowering
Double white flowers bloom from spring through fall.
Pinching
Soiree Double White doesn't require pinching. If you choose to pinch this plant, maintain at least two nodes at all times.
Spacing
Space containers 8-10 inches apart for sufficient airflow.
Height Control
While this plant doesn't require chemical growth regulators, you'll have the best results with 2500-5000 ppm B-9 if you choose to use them.
Pests
You may see whiteflies, aphids, and thrips.
Disease
This variety of Catharanthus is not particularly prone to disease. Watch for botrytis during short days; the grey rot affects plants in wet and humid conditions. Prevent this and other fungus and root rot in your greenhouse by watering at the base of your plants in the morning, providing good airflow, and spacing containers to allow the sun to penetrate to the soil.
Planting Soiree Double White Liners
We suggest planting one rooted cutting per 4-inch or 6-inch container. Plant two rooted cuttings per gallon container and three per 10-inch basket. For containers with one cutting, completely bury the ellepot in the center of the pot. In larger containers, equally space cuttings. Use well-drained soil.
Rooted Cuttings
Cuttings vary in size between different plant families. These rooted starter plants will arrive ready to be transplanted in to your final container. If they are to be used in a landscape application, you will need to establish them in a 4 inch pot or an 1801 before planting outside.

Before we take this relationship any further...
It looks like this is the first time you've added anything to your cart.
We just wanted to remind you that we are a wholesale starter plant company that sells to businesses, schools, clubs, and other non-profits. State law dictates that you must be growing for resale to order from us since we are not collecting sales tax.
If we aren't a match, we understand. It's not you, it's us.
We would look awful in orange jumpsuits.
