How beautiful! One of my favorites. Depending on where you live, you can put it in the ground. They prefer a bulb fertilizer like Bulbtone made by Gardentone. Otherwise if you live in south, you need to treat it like an annual.

I bought one of these too, but a white variety. I just kept the water level from getting too low. The flower spike ended up leaning over, once it grew out. Which can happen with these plants. It's nearing the end of its blooming cycle. I'm going to miss having the fragrance filling up my bedroom. I don't have any experience with these, but once the spike dies back, I plan on moving it into a small pot, giving it plenty of sunlight and fertilizer it until it goes dormant.

Forcing Hyacinths for Winter Bloom

Keep it as cool as possible indoors but even so the flower does not last long. Maybe 2 weeks. Do not allow the water to touch the base of the bulb. Once it has flowered you can plant it outside in the garden. Do not remove the foliage. Let it die down naturally after it's planted out. I grow lots of these every year and plant them all out.
