A big field of clover is ideal in spring and summer. Your local nursery can help with advise as to a good choice for your area. Fruit trees are also good but take several years to get very big. If you decide to plant flowers choose the ones that come back every year. I don't know of anything that will bloom in winter so you just have to be sure they have plenty of food all winter. If the queen decides to swarm they are gone. This can happen if she decides to look for a better place or if a new Queen takes over. The USDA office would be a great help. I'm sorry I can't be more help but it has been many years since I helped my Dad.
