Forcing amaryllis and muscari bulbs: An At Home Journal (Week 8)

Flower buds have formed on grape hyacinth bulbs set in a bed of marbles and growing in only water in a wide vase. Three buds are visible.

EXCITEMENT!! Discovered not one, but three buds on the muscari bulbs growing on marbles with only water in a wide glass vase. In the early evening light, they look a bit odd. I Google "grape hyacinth buds" and see two shots that look a little like what I have.

On a day when there's supposed to be a huge blizzard, I happily pull out the camera to take photographs of my muscari and amaryllis bulbs, all growing consistently. The amaryllis bulb in the largest vase has a stem tip that is fattening, making me wonder if it might bloom on a short stem.
Change the water on both amaryllis bulbs, add a little to the muscari vase and feel encouraged about this bulb-forcing project that I have taken the time to document. I am amazed that the muscari bulbs appear to have sprouted more flower buds overnight.
