Spartium (Spanish Broom)
Spartium junceum, 9 to 10 ft., the only species, is here classified as evergreen because the long, whippy flowering shoots remain green, although its leaves are rarely seen except on young plants. The main flush of large, yellow, fragrant pea-flowers is in the summer, but odd flowers appear at almost any time.
Prune established plants well to make them bushy and, if they are used for hedging, to keep them low. Sometimes the plants are badly cut by severe winters, but this only has the same effect as hard pruning and new growth always bursts in the spring. Plant from October to March in ordinaryon a dry, sunny bank.
