Black-eyed Susans (Thunbergia alata) are available in specialist shops as preferred plants for the garden and balcony. However, it is cheaper if you grow the climbing plant yourself from seeds. What you have to consider so that the cultivation of black-eyed Susanne succeeds through sowing.
Black-eyed Susan seeds are only lightly covered with soil when sown
Prepare the sowing
Prepare small trays for growing by filling them with loose growing soil. Preferably use trays for sowing that can be covered with a glass lid or foil.
The best time to sow Black-eyed Susans
Sowing can take place from February to April. Since the seeds germinate slowly, you should sow the seed as early as possible.
This is how the climbing plant is sown
Sow the seed thinly and cover it with some soil. After sowing, keep the surface moist but not wet.
The ideal germination temperature is 18 degrees Celsius. Covering the seed tray with a lid prevents the seed from cooling or drying out.
It takes up to three weeks for the seeds to germinate.
Put in pots after emergence
- Prick out in pots
- Trim tips
- Set up warm and bright
- Keep soil moist but not wet
Once the seedlings are large enough, plant three at a time in small pots filled with rich soil.
Trim the tops of the seedlings so that the plantlets branch well and later produce several shoots.
From the end of May, the plants can go outside
As soon as the danger of night frosts is over, i.e. after the ice saints, the black-eyed Susans are allowed to go outside.
Plant them in a sunny spot in the garden or put them in the largest possible planters on the patio or balcony. Make sure you have a climbing aid right from the start so that the black-eyed Susan's shoots can climb up.
It takes an average of 15 weeks from sowing to the first flower. But the hard-working climbers bloom well into October.
tips and tricks
Black-eyed Susanne owes its name to the black wreath inside the flower. In new breeds, the “eye” can also be brown or green, or absent altogether.
