Crocus are the messengers of spring, and there are varieties that bloom in the fall (but they are rarer). Most of them originate from Mediterranean region. More than several hundred species are known, but only one third of them are cultivars. Today they do not resemble their ancestors at all. They look very nice when planted in a large group. They are planted in rock gardens, on the edges of the garden, under the trees and shrubs, and may also be planted on the lawns. They’re easy to grow because they quickly adapt to the new environment. They can be grown in pots and on the balconies, and are resistant plants that can handle the low temperature, and are planted in the fall. The depth of planting depends on the type of soil, in clayey land is planted on a smaller depth. Clayey soil should first be dug up and added coarse sand, due to drainage.
