I received an Amaryllis bulb in late November or very early December and it has produced several leaves (5 or 6) but has not produced a stalk yet. . .the leaves measure about 18 inches long. I'm supporting the leaves with Amaryllis supports. Will it produce a bud?

Amaryllis are usually shipped for sale ready to bud, but sometimes the bud can be damaged during shipping or packaging, which means that it can no longer produce a bud this year.

You can keep it as a houseplant and it will bloom for you next year. Here are some articles that will be helpful:
