Cultivated tulips.

Tulips cannot be cultivated in a warm climate because they need colds nights and a cold winter to be able to grow.

Tulip bulbs are usually planted in October and November.  The period of flowering  runs from mid April till the end of May.  Apart from the cultivated tulip one also knows the ‘botanical tulip’, which is very well suitable for the garden, because  the bulbs can stay in the ground and will come out again the next year.

Cultivating new bulbs happens by planting tulip bulbs in the autumn (October and November). The buds between the tunics of the bulb grow out to new bulbs where the old bulb is used for nutrition.  The bud next to the grow point the so-called ‘A’ bud, grows out to be the bulb that can be sold for flower production, or directly to the consumer.  The planted bulb contains, next to the ‘A’ bud, between its bulb tunics, more small buds, the so-called b, c, d and e buds that will grow out to small bulbs (clusters).  These clusters are attached to the big bulb and are removed from the big bulb during husking (removal of old skin and roots) in summertime.

During the next autumn they are replanted, to grow out to a big bulb.  This way one keeps the amount of bulbs in score: the big bulbs are used for flower production or sold directly to the consumer and the small bulbs are replanted during autumn.  More than 75% of the cultivated tulip bulbs are meant for flower production home and abroad.  The rest is sold as flower bulb to the consumer or ends up in parks and public gardens.

The tulip knows many random mutations that give new colours and varieties.  These mutated tulips used to be very valuable, because they made a new line for cultivation possible with interesting new colours.

Some tulips of a certain cultivar are striped or spotted.  These effects arise due to a viral infection of the bulb, and are not transferred to a new generation when it is raised by seed.
