This is an old trick, but still fun, and it livens up any room in the house. These in the photo are in our dining area.
In spring as buds begin to swell, cut a few twigs from fruit trees or flowering shrubs. Put them in a vase with water. In a matter of days, the blossoms will open. This is also fun to do with non-fruit trees. The bare twigs will produce lovely little leaves.
