Generally, lilies (lilium) only shoot up one stem per year so unless it's a double nose bulb, don't expect anything this year. However, you didn't kill the bulb and it will come back up next Spring. It will be a little smaller, but it will still live and be back to normal the year after next. Sometimes they'll shoot up a small 'side offset' too, and if it does, let it grow. Many lilies fall victim to garden hoes, big feet and curious trowels this time of year.
