With its delicate flowers and sweet fragrance, blue woodruff is a great addition to any home. So let’s get started!

blue woodruff (Asperula odorata) is a herbaceous perennial plant in the coffee family Rubiaceae. It is native to Europe, North Africa and West Asia. The plant has a creeping rootstock and forms mats of basal leaves from which erect leafy stems arise. The leaves are oval-shaped, hairless and have small teeth on their margins. Small white flowers with five petals appear in early summer, followed by fleshy, dark blue fruits.

Blue woodruff is cultivated as an ornamental plant for its attractive white flowers and blue fruits. It is also used as a culinary herb, both fresh and dried. In Germany, the plant is used to flavor the liqueur Waldmeister.

To grow blue woodruff from seeds, sow them in late winter or early spring just beneath the surface of moistened potting soil. Keep the soil moist but not wet and provide bright indirect light until germination occurs, which usually takes place within two to four weeks. Transplant seedlings into individual pots filled with light potting soil once they have developed their first true leaves. Place the pots in a sunny location outdoors and water regularly to keep the soil evenly moist.

What You’ll Need

To grow woodruff from seed, you’ll need:

  • Woodruff seed
  • A seed starting mix
  • Peat pots
  • A propagator or warm windowsill

Sow woodruff seeds in peat pots filled with a light, well-draining seed starting mix. Place the pots inside a propagator or on a warm windowsill and keep the mix moist but not wet. Seeds will germinate in 14-21 days. Once seedlings have reached 3-4 inches tall, transplant them into individual containers filled with regular potting soil.

Sowing the Seeds

To start blue woodruff from seed, sow the seeds indoors about 6 to 8 weeks before the last frost date in your area. Fill a planting tray or pot with a sterile soilless mix, and lightly dampen it. Sow the seeds on the surface of the mix, and press them down lightly. Don’t cover them with soil, as they need light to germinate. Place the tray or pot in a location that stays between 70 and 75 degrees Fahrenheit. Water the seedlings regularly to keep the soil moist, but not soggy.

Caring for Your Seedlings

Caring for your seedlings is not difficult, but there are a few things to keep in mind. Blue woodruff likes full sun, so make sure to put your seedlings in a spot where they will get at least six hours of sunlight each day. Blue woodruff is also a fairly drought-tolerant plant, so you don’t need to water it very often. Allow the soil to dry out completely between watering. Once your seedlings are established, they will only need to be watered every week or two.

Fertilizing is also not necessary, but if you want to give your plants a little boost, you can fertilize them once a month with a diluted all-purpose fertilizer. Blue woodruff is a relatively low-maintenance plant, so it does not require much pruning. If you want to keep it about two feet tall, you can simply trim off the tips of the tallest stems once or twice a year.

Transplanting Your Blue Woodruff

When transplanting your blue woodruff, it’s best to do so in the spring or fall. Choose a location that has well-drained soil and full sun. If you’re transplanting more than one plant, space them about 18 inches apart. To transplanted your blue woodruff:

  • Water the plant thoroughly the day before you plan to transplant it.
  • Using a spade or shovel,Carefully dig up the entire plant, making sure to get as much of the root system as possible.
  • Gently loosen the roots and replant in the prepared hole.
  • Water well and fertilize monthly with a balanced fertilizer.
