In those days tulips looked very different from the ones we can see today. The tulip became so popular because of its bright colours, dramatic flames and frilly petals. Frilly petals? But these are totally smooth, I thought all tulips had smooth petals. In the 20th century it was discovered that the frilly petals and dramatic flames that gave the flower its stunning look were, in fact, the symptoms of an infection by the mosaic virus. A virus? So that's why today we think tulips should be solid, smooth and monotone. Where did the virus come from? The virus came to the tulip from a louse living on peaches and potatoes. We can still find some varieties with frilly petals today, but they are hybrids. The diseased varieties are no longer sold. Good, because I don't think my girlfriend would be too happy with sick flowers!
