Colutea arborescens syn. Colutea brevialata
Common Bladder Senna
Colutea are deciduous shrubs. They have pinnate leaves, and, in Summer, short axillary clusters of yellow or orange pea-like flowers that are followed by translucent, bladder-like fruits that, when ripe, "explode" to release the seeds within. Colutea arborescens is a vigorous shrub with pale green leaves and yellow 2 cm.flowers 2cm across, followed by 8 cm. fruits. This is a shrub that does well in coastal areas, where it will self-seed and spread. It is a low-maintenance plant

Colutea arborescens syn. Colutea brevialata
Colutea are deciduous shrubs. They have pinnate leaves, and, in Summer, short axillary clusters of yellow or orange pea-like flowers that are followed by translucent, bladder-like fruits that, when ripe, "explode" to release the seeds within. Colutea arborescens is a vigorous shrub with pale green leaves and yellow 2 cm.flowers 2cm across, followed by 8 cm. fruits. This is a shrub that does well in coastal areas, where it will self-seed and spread. It is a low-maintenance plant
Flowering
From Late Spring TO Mid Summer
Pea-like yellow or orange flowers appear in Summer
Planting
From Early Spring TO Late Spring
Colutea will grow in either poor or fertile soil, as long as it is free-draining and is in full sun. It thrives in coastal situations, and will also grow happily in a sunny border.
Propagating by seed
From Early Spring TO Mid Spring
Once established, this is a plant that will self-seed readily. The seeds are spread by the bladder-like fruit "exploding". The seed could also be collected, before the fruits open spontaneously, and sown in a seed tray in the greenhouse Spring, or in a cold-frame in Autumn, until sufficiently grown to plant out in the desired site
Propagating by cuttings
From Late Spring TO Early Summer
Take softwood cuttings from new growth early in the day in Spring or early Summer. Cut, neatly, a 4" approx. piece of a non-flowering shoot, pinch out the tip, and cut off the bottom leaves. Dip the bottom of the cutting in hormone rooting powder, and carefully place in a pot of cutting compost with the leaves just above the level of the compost. Water, label, cover with a polythene bag, and place in a warm, bright place, out of direct sunlight. Take the polythene bag off periodically for a while for ventilation (at least twice a week)
