Antirrhinum majus.Ã‚Â Snapdragon Rainbow Mix seeds are a beautiful, traditional garden favourite that have been selected for their colour richness: from the palest to the deepest pinks, coral, blood-red, and yellow. Expect some bi-coloured flowers as well. The 60cm (24″) tall stems make superb, long lasting cut flowers, and bring an intense burst of colour into flower arrangements. The stems of this old fashioned mix are sturdy, with very upright growth and uniform flowering. Grow snapdragons in moderately fertile soil and keep them watered, especially in long periods of hot weather. Choose large, deep containers for Snapdragon Rainbow Mix, with good drainage.
