Common name: Golden chain

Scientific name: Laburnum anagyroides

Hazard associated: All parts of the plant are poisonous.

Notes:

• These plants are commonly used in gardens for their showy chains of golden yellow flowers.
•  All parts, including the seeds and berries, are extremely poisonous. Eating as few as 20 seeds or 3-4 unripe berries can kill an adult.
• Traditionally, this laburnum is sometimes deliberately used to induce vomiting but as so many factors can affect the dosage strength, this is not considered a good practice in modern medicine.
• Other uses include pesticide manufacture and timber for woodturning.
