Dianthus Sweet Purple produces rich purple flower clusters on upright stems, giving bouquets a deeper color option without the heaviness of a large focal flower. The rounded blooms add texture, fragrance, and fullness to mixed bunches while still keeping a clean cut-flower shape.
Sweet Purple Selling Tips
This variety offers a rich, deeper tone that helps balance lighter bouquet colors. Its purple blooms blend easily with pinks, whites, lavenders, yellows, and greens, making it a flexible choice for seasonal and florist-style arrangements. The clustered flowers add texture and volume, while sturdy stems make it well suited for bunches, market bouquets, and cut flower sales.
General Growing Tips For Your Rooted Cutting Liner
Grow Sweet Purple in full sun or bright greenhouse conditions with well-drained soil or media. Keep the pH around 5.8–6.5 and avoid wet, heavy growing conditions around the roots. Feed regularly with a nitrate or calcium-based fertilizer such as 15-5-15 at 175–225 ppm nitrogen.
Flowering
Flowering occurs most in high-light conditions. Be aware that if high-light conditions are paired with high heat, the stems will be shorter.
Pinching
Pinching is not recommended and unnecessary for standard cut-flower production.
Spacing
A density of 4–6 plants per square foot is ideal for cut-flower production. Space garden plantings 10–14 inches apart for healthy growth.
Pests
Watch for aphids, thrips, whiteflies, and spider mites. Thrips are especially important to scout for as buds begin to form, since they can damage the blooms before harvest.
Disease
Keep an eye out for rust, Botrytis, Fusarium, Pythium, Rhizoctonia, and powdery mildew. Provide plenty of airflow, avoid leaving plants wet overnight, and use preventative rust protection for outdoor crops when needed.
Planting Sweet Purple Liners
Plane one plug per four inch container and three to five plugs per ten inch container.
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.
