Magnify glass

Thunbergia alata Arizona Glow

Black Eyed Susan

Perfect for a sunny spot

A vigorous climber that produces brightly coloured reddish-brown flowers from spring, through summer and into the autumn. The dark centres to the flowers give them an exotic charm.

Where?

This climber loves being in full sun, in a sheltered spot. It is best grown in a container and allowed to scramble through other shrubs or to trained up a trellis.

How?

If grown in a container, use a good quality potting compost and feed each week through the summer with a suitable liquid fertiliser. If planting in the ground, add some coarse grit or sand to the base of the planting hole and water sparingly. Remove faded flowers to encourage new ones.

Planting instructions

Water the plant in its pot thoroughly before planting – give it a good soaking. Prepare the area by digging a hole twice the size of the pot at least 15cm away from the wall, fence or support. Dig compost into the base of the hole. Remove the pot and position the plant – along with its supporting cane in the hole, leaning onto the support, with the top of the rootball about level with the surrounding soil. Refill the planting hole with a mixture of garden soil and compost, firming as you go. Arrange and tie the stems onto the support. Water in well and keep well watered during the plant's first year.
