I have never bothered worrying about Spring bulbs surviving cold temperatures. However, this year I had an extended cold snap along with a snow/ice storm in mid-March. Some of my hyacinths had already started to get color in the buds when the storm hit. I'm sorry to say that the cold and snow damaged the buds to the point where those bulbs won't bloom this year. The hyacinths that had flower stalks but the buds were not so far along are fine and should bloom as normal.

Keep hyacinths watered during dry spells in the fall. After plants are finished flowering in spring, cut back flower stalks but allow the leaves to die back naturally. You can hide the unsightly foliage with other plantings. An annual application of compost should provide adequate nutrients. Flower size may decline in subsequent years, so some gardeners treat hyacinths as annuals and plant fresh bulbs each fall.

"Hyacinthus is a small genus of bulbous flowering plants in the family Asparagaceae, subfamily Scilloideae. Plants are commonly called hyacinths. The genus is native to the eastern Mediterranean (from south Turkey to northern Israel), north-east Iran, and Turkmenistan.

Several types of brodiaea, squill, and other plants that were formerly classified in the lily family and have flower clusters borne along the stalk also have common names with hyacinth in them. Hyacinths should also not be confused with the genus Muscari, which are commonly known as grape hyacinths.

Hyacinthus grows from bulbs, each producing around four to six linear leaves and one to three spikes (racemes) of flowers. In the wild species, the flowers are widely spaced, with as few as two per raceme in H. litwinovii and typically six to eight in H. orientalis, which grows to a height of 6–8 inches. Cultivars of H. orientalis have much denser flower spikes and are generally more robust.

Hyacinth bulbs are poisonous; they contain oxalic acid. Handling hyacinth bulbs can cause mild skin irritation. Protective gloves are recommended."

Last fall I planted an Oriental Hyacinth mix that I bought from Colorblends. Came up really pretty this spring. I will wait and see whether they come up next spring, and if they do, how well they flower. Might just have to replant next fall.
