I was recently asked if it is still possible to plant some tulip and daffodil bulbs that were purchased a few months ago. The answer is maybe. If the bulbs have been kept cool (not frozen!) and dry, and are still plump and firm, and you can find an unfrozen patch of ground to plant them in, then go for it! You might also consider planting the bulbs in containers outside on your porch or patio. The bulbs now need to stay cold for about six weeks to trigger new growth and flowering. The odds of success are low, but better than simply throwing the bulbs away.
To enjoy flowering bulbs indoors, look to your local greenhouse or garden center. They will be offering potted, blooming spring bulbs like hyacinths, daffodils and tulips very soon now.
