CHINESE FORGET-ME-NOT
Cynoglos sum amabile
The Chinese forget-me-not is a charming annual that produces a multitude of small indigo-blue flowers from mid-spring to late summer. This fast-growing, bushy plant reaches up to 50 cm (20 in.) in height.
Easy to grow, it thrives in pots, containers or garden beds, even in partial shade. Let it self-seed naturally or harvest the seed heads after blooming.
Sowing Period
-
Direct sowing: Early spring, as soon as the soil can be worked — even if light frost is still possible.
-
Indoor sowing: 6 to 8 weeks before the expected outdoor planting date.
Seeds typically germinate within 5 to 10 days, especially when the soil is kept between 18–24°C (65–75°F).
Choosing the Right Spot
-
Light: Full sun or partial shade
-
Soil: Ordinary, well-drained, with a neutral to slightly acidic pH
Avoid overly rich soil, which can lead to weaker plants.
How to Sow
-
Depth: Sow seeds about 5 mm (¼ in.) deep
-
Spacing: Space plants 20 to 30 cm (8–12 in.) apart
-
Indoor sowing: Keep seeds in complete darkness until germination, then move to bright light.
Care
-
Watering: Keep the soil slightly moist, without overwatering
-
Maintenance: Remove faded blooms to encourage continuous flowering and prevent self-seeding
-
Bloom period: June to August
Little Gardener’s Glossary
When you sow seeds, you grow seedlings!
Sowing usually happens indoors in small pots (or in a greenhouse).
After a few weeks, when your seedlings are strong enough, you can gently plant them outside where they’ll continue to grow and bloom.
When and how to start seedlings?
Between February and April, as nature wakes up, sow your seeds indoors in small containers placed near a bright window.
Keep the soil slightly moist, and in no time, tiny green shoots will appear.
When nighttime temperatures stay above 10°C (50°F), it’s time to move your plants outdoors.
🌱 You can also sow directly into the soil once the weather is warm enough (May or June, depending on your region), but flowering will be a little later.
-
Sowing in pockets: Place a few seeds together in a small hole.
-
Broadcast sowing: Scatter the seeds freely across your prepared area.
