Flower bulbs are available in different sizes. This may be somewhat confusing, as buyers may get the impression that one supplier is cheaper than the other. However, this is not the case. When it comes to purchasing bulbs, the slogan ‘big is better’ applies. It is a simple fact that larger bulbs produce more or larger flowers than small bulbs. Here you see an example of the difference in flower production of a larger and a smaller bulb of the Endear daffodil. On the left is a size 10/12 bulb, most commonly the size of cheaper daffodils. The bulb produces one single stem with five little flowers. On the right the very same daffodil in a bulb size 14/16, the size Fluwel has on offer. Four stems sprout from one single bulb, two of which have five small flowers, two with three and one with two flowers – I know this for a fact, as I carefully peeled open the buts on order to count the flowers inside. The last bulb in a larger size produces no less than fifteen flowers, three times as many as the cheap daffodil in a smaller size that looked like such a good deal. When it comes to purchasing flowers bulbs, keep in mind that size absolutely does matter.
At Fluwel, we pay a lot of attention to obtaining large bulbs. Why go through the trouble of planting, only to spoil the end effect by using smaller bulbs? Your savings will be negligible and much of your time spent digging will seem wasted. Larger bulbs simply produce superior plants with more impressive flowers.
Here is a tool most Dutch bulb growers use. Its holes allow one to measure the size of the bulbs in an instant.
Bulb size is measured by circumference in centimeters. When you see a tulip variety listed as size 12cm+ it means that the bulbs won’t fit through a hole less than 12cm around (incidentally, this is generally the largest size for tulips).
