Question

As summer ends and fall begins, you can still enjoy spring flowers inside! It's an easy way to make your home look pretty．Some flowers grow from seeds．Other flowers grow from bulbs (球茎)．Some bulb flowers are easier than others to grow inside．A good one to try first is called a paperwhite．As many as twelve sweet-smelling flowers can grow from one paperwhite bulb．

But how can you grow one inside? Please follow those steps below:

1.Find a large glass jar (罐) that is clear enough to see through．Fill the jar almost to the top with stones or shells．This will give the bulb's roots something to hold on to as they grow．It will also give you a place to set the bulb．

2.Place the bulb on top of the stones．The bottom of the bulb is the part that is pointed, like the bottom of a heart shape．Push the bulb into the stones just far enough to make it stay．

3.Fill the jar with water．Use just enough water to cover just the bottom part of the bulb．

4.Put the jar in a place where the bulb will get plenty of light．Check every day to make sure there is still the right amount of water in the jar．Add water when it is needed．Soon the roots will start to grow．In a few weeks, you can enjoy watching the flowers bloom (开花)．
