Description

A touch of magic shines in your garden with the wild crocus 'Firefly'. The striking purple flowers with their bright yellow throats attract everyone's attention. Particularly fascinating is the different coloring of the inner and outer petals, which give this crocus a unique beauty. The delicate flowers appear from February onwards and provide a valuable source of food for the first beneficial insects such as bees and bumblebees. The wild crocus 'Firefly' is ideal for your pot, box or home garden and also likes to grow wild. Make sure to store the bulbs in a dry and airy place so that they retain their high germination capacity. 'Firefly' propagates quickly and ensures an ever-growing sea of flowers in your garden year after year.

Growing tips

Location and soil Early-flowering botanical crocuses thrive best in sunny spots in the garden, while the autumn-flowering crocuses also do well in semi-shady spots. The large-flowered hybrids, i.e. the classic garden crocuses, prefer a sunny to semi-shady location. However, it is important to know that the longer the location is shaded during the day, the sparser the flowering. What they all have in common is their preference for well-drained soil, as waterlogging causes the tubers to rot. While the spring-flowering species also thrive in sandy or stony soils, the autumn crocuses prefer a good garden soil with a clay content. For early bloomers, on the other hand, you should improve heavy soil with a little sand. Planting The best time to plant spring-flowering crocuses is from October to November, while fall-flowering species are best planted in August. The planting depth for spring-flowering crocuses is six to ten centimetres, as is the distance between the bulbs. Autumn-flowering crocuses are planted a little deeper because of the larger bulbs. As crocuses use their traction roots to access nutrients and moisture from deeper soil layers over time, it is not a problem if the tubers are planted relatively shallowly. Always place about ten bulbs next to each other, as the small flowers are best displayed in groups. If you want to turn your lawn into a crocus meadow, a loose, random distribution is recommended. The golden crocus (Crocus flavus), spring crocus, small crocus and elfin crocus are particularly suitable for growing wild. They form dense clumps that should be divided after a few years. Care tips Crocuses do not require any special care once planted. It is important not to cut off the leaves immediately after flowering. They should only be removed when they wilt, otherwise the plants will be weakened and die more quickly. Therefore, if you have planted crocuses in the lawn, you should wait until the leaves have yellowed before cutting them back. If necessary, fertilize in early spring as soon as the leaves sprout. An organic liquid fertilizer that is applied with the irrigation water is suitable.
