Honeywort, also known as Cerinthe, is a beautiful and easy-to-grow annual plant that produces clusters of unique blue and purple bell-shaped flowers on tall stems. Easy to grow in beds and containers, Honeywort is nectar-rich, attracting hummingbirds, butterflies, bees, and other pollinators. Honeywort also makes for a great cut flower, holding up nicely in vases. During the coolest part of the day, harvest when bracts darken and are at their peak color. While in fresh, clean water, Honeywort should last about seven to ten days.
When to Plant Honeywort Seeds
Honeywort seeds can be started indoors four to six weeks before the average last frost or planted directly outdoors in spring after the danger of frost has passed. If you are starting seeds indoors, make sure you have a sunny windowsill or grow lights available.
Where to Plant Honeywort Seeds
Once the seedlings have grown a few inches tall, have developed a few leaves, and the weather is reliably warm, they can be transplanted into larger pots or directly into the garden. Make sure to plant them in well-draining soil in a sunny location with 12 to 18 inches between plants.
How to Plant Honeywort Seeds
Soak Honeywort seeds overnight in water to speed up the germination process.
If you are starting seeds indoors, plant the seeds individually in small pots or plugs filled with moist potting soil. Make sure to plant them at a depth of about ¼ inch. Keep the soil moist but not waterlogged. Use a spray bottle or a gentle watering can to avoid disturbing the seeds. Honeywort seeds require plenty of light to germinate and grow. Place seed trays in a sunny location or under grow lights. Expect germination in three weeks if the temperatures remain between 65°F and 85°F.
If you are planting seeds outdoors, sow them directly into well-drained soil in a sunny location. Space each plant 12 to 18 inches apart.
How to Care for Honeywort
Honeywort plants require minimal care. Water them regularly and fertilize them with a balanced, water-soluble fertilizer once a month during the growing season. Remove spent flowers to encourage more blooms.
