I've grown a number of different Thunbergia as summer annuals. This year's feature has been Thunbergia 'Sunshine Susie Red and Orange', a cutting grown variety readily available as small plants early in the season. Three of these in terracotta pot are growing well up a simple cane framework attached to two downspouts on my house wall. They've easily reached 8ft / 2.5metres and have produced a continuous sprinkling (it's been too cool and wet for more) of 2in / 5cm reddish orange flowers with contrasting black eyes.

Eccremocarpus scaber now comes in a variety of colours, from rarely seen white, through more common yellow, the orange form I've illustrated below, and back to scarcer red. It's a bit pot luck with a packet of seeds - and who has the room to grow a couple of dozen seedlings on to find the elusive white or red forms? Not me, I'm afraid. For all that, even the commoner yellow and orange forms are attractive as they wend their ferny annual foliage through whatever support is handy. They will seed around and can survive for a number of years through self sowing but plants are rarely as impressive as seed sown early in the year - even the previous autumn - and then grown on in some protection until late spring planting.
