Further words about cultivated tulips are unnecessary because a vast number of sorts are to be found in almost each garden today. Unfortunately many cultivated tulip sorts tend to stunted growth in the medium term. But cultivated tulips are only arisen from the wild tulips (also called botanical tulips) by cultivation and selection within the last 400 years. In Germany, you can find also one species, namely the Wild Tulip (Tulipa sylvestris). Depending on the source exist 70 to 150 botanical tulip species, whose Mayn range are the steppes of Central Asia. Most botanical tulip species are frost-hardy and tend in the long term, in contrast to cultivated tulips, to reproduction in the case of congenial conditions.
To the greatest extent wild tulips are concering their habitat preferences relative uncomplicated. Ideal is moisture in spring and warm and dry summers. During this time the new produced tulip bulbs are maturing. Waterlogging and voles niggle wild tulips.
Best planting time is between the end of September until early December on frost-free days. Give the tulip bulps at least twice to three times as deep into earth as the bulb is high. It is advantageous if you give at first some sand into the planting hole and hereupon put the bulb. Wild tulips blossom for years and set regularly seeds, which can be left on the plant until they are matured. By sowing, stolons and side bulbs many species produce larger stocks in the long term. However, until a by sowing propagated tulip blossoms for the the first time, it may last five years.
In late autumn 2009 I planted of 12 species all in all circa 400 bulbs within my lawn.
The bulbs survived excellently their first severe winter. In the following spring the bulbs spouted almost to hundred per cent. Most plants blossomed as well as produced seeds. Arising thereby, I had my first difficulty. I planted the bulbs in a still relative nutrient-rich meadow, so that at the moment of seed maturation in the end of May bis early June the bolls are almost complete vanished within the half of a metre high grass.
Summer 2010 was very rainy and was so almost out of keeping with the ideal conditions of a hot and dry summer, which the bulbs require for maturing. Thus I am curious, which survival rate arises the next year.
Against expectations the moist and cool summer 2010 did not damage the bulbs. In the end of February almost all species stspeciesed with budding. According to a first count many species proliferated in 2010: The populations are circa 15 – 20% greater.
Number of individuals has again evolved delightfully, so that I have planted further species.
In the case of most species it came again to a population increase. Tulipa greigii and Tulipa praestans reproduce well, but are lazy about blossoming. Unfortunately Tulipa altaica and Tulipa whittallii fell prey to voles.
This year population increase stagnated. By contrast, a slight increase is recorded in the grape hyacinths and wild crocuses.
The cold and wet summer of 2014 badgered the tulips. This year, only some species on drier sites came to flower. By contrast, the wild crocuses showed a good population development.
Currently, I am cultivating the following species in my garden.
