Senna corymbosa

Senna corymbosa
Aka Cassia corymbosa. A splendid South American subtropical shrub that produces a succession of large rich golden yellow flowers over dark green pinnate leaves through the summer.
Lapageria rosea, & Senna corymbosa
This species can be grown in a sheltered situation outside in the UK and can put on a wonderful display after a mild winter. After a hard winter it tends to get cut by frost but this just means it begins to flower later in the autumn.
Lapageria rosea, Senna corymbosa & Buddleja salviifolia
The parent plant of these has lived against a south facing wall in mid Sussex through at least the last 10 years and always came back vigorously and flowered before the autumn frost came. If in doubt - mulch heavily, or alternatively, an excellent pot plant for patio or cool greenhouse.

One of a number of peculiar herbaceous perennial (non-climbing) species from the eastern USA. This one makes a pale leafy clump to about 12ins high with fuzzy-felty rounded nodding white flowers over quite a long period in early summer.

Very intriguing and a great favourite here. Easy on a well drained soil in sun.
