About Colchicum bivonae
Colchicum bivonae, also known as Autumn Crocus or Nättidlösa, is a beautiful bulbous plant belonging to the Colchicaceae family. It is distinguished by its delicate, cup-shaped flowers that emerge directly from the ground in autumn, without leaves, in shades ranging from pale pink to intense mauve, often with a reticulated pattern. It is ideal for rock gardens, path borders, or for naturalizing in lawns, providing a surprising splash of color when many other plants have already finished blooming.
Native range
Eastern Mediterranean region, including southern Italy, the Balkans, and Turkey
Care tips
It requires a location in full sun or light partial shade and well-drained soil, preferably sandy or gravelly, to prevent waterlogging that rots the bulbs. Watering should be moderate during autumn flowering if the weather is dry, but it is crucial to avoid excessive moisture, especially during its summer dormancy period. A common mistake is planting them in heavy or clay soils without improving drainage, which can lead to corm rot. Light fertilization is recommended in spring when the leaves appear.
How to save a dying Colchicum bivonae

- What kills it
