Frequently asked
- Which colour is classic?
- Deep blue is the trademark. Giving delphinium means giving blue — other colours are rare and pricier.
- In a bridal bouquet?
- Very popular for 'something blue'. Slightly formal — fits classic weddings, less rustic farm looks.
- Is delphinium toxic to cats and dogs?
- Yes, significantly. All plant parts contain diterpene alkaloids (including delphinine) and are toxic to cats, dogs and horses. Young shoots are the most potent. Keep the vase out of reach of pets and clear away fallen florets promptly.
- How long does delphinium last in a vase?
- Around 5 to 9 days. Deep, fresh water changed every two days and a cool spot noticeably extend its life, as the blooms are sensitive to ethylene.
