I recently purchased a hyacinth plant (bulb) in a small glass vase. In the 2 weeks i have had the plant it has bloomed w/beautiful fragrant pink flowers. Question: has it continues to bloom it is now top heavy. Can i keep it in a bigger vase of just water forever or in spring plant outside? The only care INSTRUCTION WAS TO KEEP 3/4 FULL W/WATER. Should the bulb not touch water? It doesn't in the purchased vase.
