Zinnias are a classic summer favourite - coming in every colour, size and shape available. They have a daisy-like head and a cheerful appearance. If you're gifting flowers, the last thing you want them is to die after only a few days - Zinnias have incredible lasting powers of up to 3 - 4 weeks. If you're giving them to a friend with pets, they are also pet-friendly and non-toxic.
Zinnias need to be picked once they are fully in bloom, otherwise, they won't last as a cut flower. If the stem is stiff and the bloom fully upright, it is ready to be cut. Once in the vase, they benefit from a drop or two of bleach as they are considered to be a 'dirty flower'. They are also sensitive to the cold, so don't place into the fridge.
