Toskanischer-Krokus 'Zwanenburg'

Season Overview

Description

What a sight when the Tuscan crocus 'Zwanenburg' produces its magnificent purple flowers from February onwards! The flowers stand out particularly well against the dark green leaves. Crocus etruscus 'Zwanenburg' thrives when planted in a sunny to semi-shaded location with well-drained, loose, nutrient-rich, sandy soil. It grows upright and reaches heights of 10 cm to 15 cm with a width of 5 cm to 8 cm. The Tuscan crocus 'Zwanenburg' is also very decorative in pots or boxes.

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 will be. 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 the species that flower in the fall are preferably 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.
