Laburnum anagyroides

Large shrub or small tree, 5-7 m tall, 3-4 m wide, main branches vertically upright with loosely overhanging twigs; medium to fast-growing.

Light yellow, loose racemes in May.

Like beans, poisonous.

In threes, medium-green.

Relatively shallow, not well anchored.

Sunny to slightly shady, needs warmth, moderately frost hardy, good for urban areas, sensitive to wind.

Dry to fresh, for loamy but not too dense substrates, prefers chalk.

Wear themselves out with profuse flower production; they are generally short-lived; replace with new plants after 15-20 years; do not cut radically.
