FAQs
What is the best time to sow Black Eyed Susan seeds?
Sow seeds indoors 6-8 weeks before the last expected frost date. Transplant outdoors after all danger of frost has passed and the weather is reliably warm.
Can these seeds be grown in cooler climates?
While they prefer warmth, they can be grown in cooler climates if started indoors early and transplanted into a very warm, sheltered spot or a conservatory. Protection from frost is essential.
How tall do Black Eyed Susans grow?
Their growth habit is either climbing or trailing. Depending on support, they can reach heights of 1-2 meters (3-6 feet) when climbing, or trail effectively over edges.
What does 'Susie Mix' mean?
Susie Mix indicates a blend of varieties within the Black Eyed Susan (Thunbergia) family, offering a range of colors including orange, yellow, and white, often with distinct dark centers.
How often should I water my Black Eyed Susan plants?
Water regularly, keeping the soil consistently moist but not waterlogged. Reduce watering slightly in cooler conditions or if grown in a conservatory.
Do I need to provide support for these plants?
Yes, if you want them to climb, provide stakes, netting, or a trellis. If you want them to trail, ensure they have a suitable edge to grow over, such as a wall or container rim.
Troubleshooting
Seeds are not germinating
Ensure seeds are kept consistently warm (around 21-24°C) and moist. Avoid overwatering. Try using a heat mat if germination is slow.
Seedlings are leggy or weak
Provide more light immediately. Ensure adequate spacing between seedlings to prevent overcrowding and competition.
Plant is not flowering
Ensure the plant is receiving enough sunlight and is in a warm, sheltered location. Check for adequate watering and nutrients. Deadhead any previous blooms.
Leaves turning yellow
This could be due to overwatering, poor drainage, or insufficient nutrients. Adjust watering schedule and ensure the soil drains well.

Setup, Compatibility & Care
Sowing: Sow seeds indoors 6-8 weeks before the last frost date in a warm location (around 21-24°C or 70-75°F). Use a seed tray with a good quality seed compost. Cover lightly with compost or vermiculite. Keep moist and warm.
Transplanting: Once seedlings have developed their first true leaves and the risk of frost has passed, transplant them into pots or their final growing positions. Ensure the location is warm and sheltered.
Growing Conditions: Black Eyed Susan thrives in full sun to partial shade. They prefer well-drained soil. Water regularly, especially during dry spells, but avoid waterlogging. Support climbers with stakes or netting.
Care: Deadhead spent flowers to encourage further blooming. Protect from strong winds and frost. If grown in pots, ensure they are large enough to accommodate root growth.
