As noted earlier this week, I have hyacinth in bloom. So far, all pink, but the blue flowers will not be far behind. ANYONE can grow hyacinth in vases like this. There is little to no effort involved. First, buy a hyacinth vase and bulb. I think if you buy as a kit, the bulb has already been kept at a cool temperature. If you do like I do and just buy the bulbs to use with vases you already have, just buy a bag of hyacinth bulbs in the fall and store them in the back of the refrigerator for 10 weeks or so.
Step 2, remove the bulbs from the refrigerator around January 1, place them in the vases with some water, and leave them alone. I did check water levels once and added a bit of water to a few of them a few weeks ago. That’s it. They are doing this all on their own.
I’ve only known of one person who couldn’t get their bulb to bloom, and that was because she didn’t realize which end was up. Flat end goes down, tip goes up! “Practically” fool proof!
