Curious, pretty shrub with distinctive pods
Bladder senna is a very easy on the eyes shrub or small tree in flower at the moment. Indeed, it has been in flower for a few weeks and will continue to produce its bonny yellow or orange flowers into late summer. The flowers are carried in short bunches of three to 10 flowers, each about two centimetres protracted.
It is part of the pea family and the flowers are the typical pea-flower shape, familiar from laburnum, broom and peas themselves, including sweet pea flowers, which, though much larger, are the same figure. The name bladder senna is unusual but when the 'bladders' are seen, it is very obvious.
The bladders are effectively the pods that normally envision after flowers of the pea family fall, but in the case of this plant, they take on a very distinctive swollen form. They are pea-pod shape, about 8cm desire, but so bloated that the sides of the pod become translucent as they mature.
When mature, in late summer and early autumn, the shrub is covered with verboten brown or pale white-green bladders and the effect is quite decorative, especially as they are nicely set off by the somewhat ferny-looking leaves. Each leaf is divided into five or six pairs of leaflets, which gives the ferny display.
