The Protea is one of the most durable cut flowers in a bouquet and is the longest-lasting cut flower out of the water, which is handy to know if your bouquet can’t get to a vase for a little while. They are native to Africa and are drought-tolerant. Proteas are an excellent cut flower as they are long-lasting and add spectacular texture, colour, and form to a bouquet of flowers. Most proteas have a vase life of between 7 and 14 days, and some varieties can even last up to 21 days with proper care.
