Thunbergia alata 'Lemon Star'

Black-eyed Susan is a native of east Africa and, as might be expected, enjoys warm, slightly humid weather with shelter from cold winds. It used to be regarded as a conservatory climber, but it's now regularly grown outdoors, both in hanging baskets and in more protected corners of the garden.

Thunbergia alata ‘Lemon Star’ bears bright yellow flowers with a contrasting dark brown eye. It's a vigorous climber, and will quickly cover a trellis or obelisk. Grow in moist but well-drained soil in a sheltered, sunny spot. It can also be grown in containers.
