Lily of the Incas, Lily of Peru, not so easy but so beautiful!

The lily of the Incas, also called lily of Peru in still alstromer, is a beautiful bulbous plant that looks like a tropical plant. It bears its name because it comes from South America and probably more precisely from Peru. It is its flowers with petals of different lengths and shapes that make us think of orchids for example. The colors and in particular the spots on the petals also play a role as its long colored stamens. Alstroméria likes to be cultivated in soil rich in humus, well drained, deep and light, it is under these conditions that its root system will develop best. There are many varieties as well as many colors and therefore necessarily the ones you dream of for your garden. The plant is not very hardy, down to -8 ° C, in mild regions the bulb can remain in place where in the coldest it will have to be sheltered from winter by thick mulching of dead leaves. The plant is easy in the garden but you have to be careful about its establishment. In hot regions with strong sun, we prefer partial shade, in regions with less biting sun, full sun exposure will suit it perfectly. Either way, ideally we will shelter the alstromeria from the wind.
