Fun Fact: Hyacinth is a cousin of Asparagus!
Hyacinth is another flower synonymous with Spring. It grows in easter-egg colors of white, pink, purple, blue, and yellow, and smells just like Lilac flowers. Hyacinth is native to the Mediterranean and has been around for a very long time. It is even mentioned in Homer’s Iliad! Each bulb produces one stalk on which dozens of tiny flowers bloom. Hyacinth, like other Spring bulbs, are wonderful plants for pathways and borders, and also grow very well when planted in pots. Plant with Crocus and Tulips for waves of Spring blooms! In Flower Language, Hyacinth is rather impish as it represents things like playfulness and rashness, though each color has a different meaning, and can also represent sincerity.
HYACINTH PLANTING AND STORAGE:
Hyacinths begin as bulbs, and those bulbs are planted in the Fall. You can plant tulip bulbs directly into your garden (they make lovely path liners), or into a pot stored in a cool (but not cold) dry, dark place through Winter. A good example would be an unheated garage, or shed, or a cold frame. The idea is to keep them cool but safe from rapid changes in temperature. Hyacinth bulbs can also be stored in a way that prepares them for being “forced” in glass vessels in Spring. Place them in a container and add soil, then a layer of bulbs stored close together but not touching, add a layer of soil deep enough to allow room for roots to begin to develop, and then plant another row, and so forth until all of your bulbs are planted. Moisten the soil and keep it from drying out, but do not over-water. Storing Hyacinth bulbs in this way can help your bulbs survive and begin to develop roots in order to be able to “force” the bulbs in a glass vessel in the Spring.
Hyacinths, and all bulbs that bloom in the Spring, need to make their home in soil that is kept moist but never soggy. These bulbs can be a favorite of squirrels, and they will often dig the bulbs up over the Winter for a nice big meal. To prevent this from happening, we have had success with staking hardware mesh over the areas that bulbs are planted in, and removing the mesh once the plants start to bloom. All bulbs should be planted in orientations and at depths specific to the plant. For Hyacinth, plant the bulb pointy side up in a hole that is about 6 inches deep. It’s a good idea to loosen the soil at the bottom of the hole, as well. Hyacinths prefer a sandy/loamy soil and full sun.
FORCING BULBS IN THE SPRING:
To “force” bulbs in the Spring, select either a vase created specifically for allowing these bulbs to grow and bloom without soil, or a tall, slender vase and line the base with a generous amount of stones, nearly to the top of the vase, and place your bulb on top of the pebbles. You will fill the water to just under the base of the bulb, and keep the water at that level until roots form. At that point, keep the roots in water at all times until the bulb has bloomed. To prepare the bulbs for blooming, place them near a very bright source of light (a grow light is best) until they begin to develop leaves. Make sure the area they are stored in to soak up the light is no warmer than 65 degrees Fahrenheit at any given time. They are now ready to go in your vessel to bloom!
You may reuse bulbs again and again, but they must be allowed to collect energy from the sun via their foliage. The easiest way to accomplish this is to plant the bulb in some soil and place it in a spot where it will get plenty of sun. Wait until the foliage has browned and withered, then dig up your bulbs and store them as before.
