Iberis (also known as Iberis Sempervirens or Candytuft) is a perennial flowering plant native to central Europe. Snow Cone Forte has a mounding habit of 5-8" tall and 9-12" wide with white conical flowers that bloom in early to late spring. Foliage is evergreen in zone 3-9, where Iberis flourishes in sunny borders and containers. This plant is resistant to drought, deer, and rabbits while attracting pollinators to the garden. This variety developed by Syngenta requires vernalization and typically offers a second bloom when it is cut back after the first. Forte is faster-growing with smaller blooms and denser branches than Snowcone Improved. For a purple variety, try First Flush Lilac.
Snow Cone Forte Selling Tips
Sell Iberis to customers looking for a low-maintenance perennial for a border or container. Snow Cone Forte offers many benefits, including small conical white flowers, evergreen foliage, and a compact mounding habit. This plant attracts pollinators to the garden while resisting deer and rabbits and tolerating cold temperatures. With little care, Snow Cone flourishes in full sun, bringing visual interest to the landscape in early spring. Create an attractive border by pairing Snow Cone Forte with Artemesia and early spring bulbs.
Coach Your Customer
1. Space plants 9-12" apart in well-drained soil in full sun.
2. Water regularly during the first season as the plant establishes roots.
General Growing Tips For Your Rooted Cutting Liner
For best results with Snow Cone Forte, plant one plug per 4-inch or 6-inch container. Use well-drained soil with a pH of 5.6-6.0, and either SME EC of .9-1.3 mS/cm or PourThrough EC of 1.4-2.0 mS/cm. Use 100-150 ppm feed during bulking and vernalization and then reduce to 75-125 ppm during finishing. Maintain temperatures of 64-66 degrees during bulking, then 37-40 degrees during 7-8 weeks of vernalization. Finishing temperatures should be between 58-70 degrees. This plant requires bulking and vernalization, finishing in 19-22 weeks. Start plants in the fall for spring sales. Plant Forte slightly later as it grows faster than Snowcone Improved. You may see aphids or thrips, and downy mildew can affect Iberis in wet, humid conditions.
Flowering
Small conical white flowers bloom from early to late spring.
Pinching
This plant doesn't require pinching.
Spacing
Space containers for adequate airflow around the base and foliage of each pot and to allow sunlight to penetrate to the soil.
Height Control
This plant doesn't require PGRs. However, you may apply 3-5 ppm Bonzi to hold plants before flowering.
Pests
You may see aphids or thrips.
Disease
Snow Cone Forte can be susceptible to downy mildew. This fungal disease occurs when the days are wet and humid. It causes drooping leaves and yellow and brown spots. Treat downy mildew with a fungicide to prevent excessive leaf drops. Most importantly, prevent downy mildew by providing adequate airflow in the greenhouse and plenty of space between containers, watering at the base of each plant in the morning and allowing the soil to dry out between waterings, and growing plants in a location with full sun.
Planting Snow Cone Forte Liners
We recommend planting one rooted plug per 4-inch or 6-inch container. Use well-drained soil and completely bury the ellepot in the center of the pot.
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.
