Stock Column Pacific Blue, also known as Matthiola incana, is a stately upright annual originally native to the Mediterranean region. This professional-grade cultivar is part of the Column series, prized for its single-stemmed habit that produces a dense, showy spike of ruffled, clear blue flowers with an intoxicatingly sweet, clove-like fragrance. Reaching a mature height of 24-30 inches, these plants thrive in full sun and rich, well-drained soil during the cooler months of spring and autumn. They are an essential architectural element for garden borders and a top-tier choice for premium fresh floral arrangements. For a sophisticated spring display, try pairing Pacific Blue with companions like white snapdragons, Ammi majus, or larkspur.
Stock Column Pacific Blue Selling Tips
Sell Stock Column Pacific Blue to customers looking for nostalgic fragrance and dramatic vertical structure for their early spring arrangements. This series is the industry gold standard for cut flowers because it provides the uniform flower quality and incredible stem strength required for professional "line" work in floral design. Your customers will love that the large, ruffled blue blooms stay vibrant and fragrant for 5-8 days in a vase. Its ability to thrive in cool temperatures ensures the garden stays full of color and scent during the early season when many other plants are just starting to grow.
Coach Your Customer Choose a planting site that receives at least six hours of full sun to ensure the most fragrant and sturdy flowering spikes. Maintain consistent soil moisture, especially during the first few weeks, to help the root system establish properly in the cool spring soil. These are cool-season annuals that will provide beautiful color and scent until the high heat of mid-summer arrives. Since these grow on a single, sturdy spike, never pinch the plant, as this will destroy the primary flower.
General Growing Tips For Your Seedling Tray
For high-quality professional production, plant one rooted liner per 4-inch container using a well-drained media. Maintain your soil pH between 5.8 and 6.5 and provide a constant fertilizer feed of 175-225 ppm Nitrogen. As a cool-weather crop, Pacific Blue should be finished with daytime temperatures of 55-65°F and night temperatures of 50-60°F to ensure high quality and prevent flower bud drop. This variety typically finishes from transplant to sale in about 10-12 weeks. Be sure to provide high light levels during production and watch for common issues like aphids, thrips, and botrytis.
Pinching
It is very important to remember that you should never pinch Column Stock; these plants are bred to produce one magnificent, high-quality central flowering spike.
Spacing
For greenhouse production, we recommend spacing your 4-inch containers 6-7 inches apart on center. This proper spacing allows for necessary airflow and sunlight penetration, which are the best preventative measures against foliar diseases and stem legginess.
Pests
Regularly scout your crop for aphids and thrips, which can damage the tender developing buds.
Disease
The most common issues are botrytis and powdery mildew, especially during periods of high humidity.
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.
