Do hyacinths grow outside where you live?
I put mine outside (in pots) over summer, feed until foliage dies down, then bring them in before hard frosts, they flower in spring. If you want them for next Christmas i think you have to cold treat them to make them think its winter, then put them in a dark place in about September, bringing out when the shoots show.
I had some paperwhite narcissi last year, still waiting for flowers to show. Hyacinths are never as good as first year, but do flower and scent.
