There is a product called Gibberellic acid. It is use it to induce flowering on some kinds of plants.

Never tried it on bulbs, but Amaryllis are a form of grass - monocot.

Hudson seed sells it. http://www.jlhudsonseeds.net/GibberellicAcid.htm

Here is a guy in NZ that you might direct your questions too. http://www.gibb-gro.co.nz/aboutus.html

All those bougainvillea that you see blooming at the big box stores are treated, but I think they use Florel. Makes the plants bushy, but, delays flowering. I am pretty sure that it's generally used only on broad leaf plants. Might be worth trying since it is not expensive.

I have used Florel and one of the 'side effects' is that treated plants will blooms out of their normal season about 6-7 weeks after treatment.

Here is an info sheet from the folks I buy it from http://www.southernag.com/docs/labels_msds/florel.pdf
