You can also get parrot tulips that has ruffled petals, fringed tulips with serrated edges and goblet-shaped tulips called lily-flowering. You can also sometimes find what is called French tulips. They are specially grown for the florist trade as they have bigger flowers and much longer stems and the price is accordingly.
Tulips come in a very wide variety of colours from pink, purple, white, red, orange and yellow to striped and variegated colours.
If you look after them they can last for about 5-10 days.
Condition the flowers as soon as you come home by removing any leaves that would end up below the waterline in the vase, as well as any broken or damaged leaves.
To make sure your flower last as long as possible re-cut the stems every 2 days, clean the vase and fill the vase with fresh cool water.
Tulips are both phototropic and geotropic - they reach for the light and they are affected by gravity. On top of that they also continue to grow in the vase as much as five centimeters. So this is why they keep bending, reaching and move around in the vase.
Some people like their tulips straight and if that is the case, you can after conditioning the flowers, try wrapping them tightly in newspaper and leave them in water for a while. Some other ways is to use a vase with a just big enough opening that will support the flowers, another is to cut the stems short and use bottles or bud vases.
I have also found that a lot of people like their tulips to 'dance around' in the vase and let them do their own thing.
Whichever look you prefer tulips will always be a beautiful and welcome flower at this time of year.
