Winter White, also known as Arenaria Montana or Sandwort, is a perennial flower native to southwest Europe. Syngenta developed this cultivar as a compact variety that blooms without vernalization. It offers an upright mounded habit of 4-6" tall and 10-12" wide with white flowers from early to late spring. Perennial in zone 6-9, Sandwort flourishes in full or partial sun with moderate water, bringing whimsy to patio containers, cottage and rock gardens, and landscape borders. For a longer blooming variety, try Summer White.

General Growing Tips For Your Rooted Cutting Liner
For best results with Winter White, plant one rooted liner per 4-inch container or two per gallon container. Use a well-drained soil with a pH of 5.8-6.2, EC of SME 1.5-2.1or PourThru 2.3-3.2, temperatures of 66-68 daytime and 56-58 nighttime, and light feed (75-125 ppm N). Use a Bonzi drench if needed. This plant needs long days (14 hours of 4,000-6,000 fc). This plant benefits from 7-8 weeks of cold treatment at 50 degrees on average but doesn't require vernalization. You may see aphids. This plant can be prone to root rot, Botrytis, and powdery mildew in wet conditions.
Flowering
White flowers bloom from early to late spring.
Pinching
Pinch once.
Spacing
Space containers for adequate airflow around the base of each plant and to allow sunlight to penetrate to the soil level.
Height Control
This plant doesn't typically require PGRs. Use a Bonzi drench of 10-20 ppm if needed.
Pests
You may see aphids.
Disease
Winter White is prone to rust and should be sprayed preventatively. In overly wet conditions, root rot, botrytis, and powdery mildew can infect Arenaria. Prevent these conditions by taking some simple precautions.
1. Water at the base of each plant in the morning and allow the soil to dry between waterings.
2. Space containers for airflow around each plant and to allow sunlight to penetrate to the soil level.
3. Provide adequate airflow in your greenhouse. We recommend using horizontal airflow fans.
Planting Winter White Liners
We recommend planting one rooted liner per 4-inch container or two per 6-inch or gallon container. Use a well-drained soil and completely bury the ellepot in the center of the container or evenly space the ellepots in gallon containers.
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.
