What Is A Bulb Jar: Bulb Vase Info For Forcing Flowers
By: Mary H. Dyer, Credentialed Garden Writer
If you’re interested in forcing bulbs to bloom indoors, you’ve probably read about bulb forcing jars. Unfortunately, available information doesn’t always provide much detail about bulb glasses for flowers and how bulb glass vases work. The idea of bulb forcing jars may seem complicated, but it’s much simpler than you may think. Read on for some helpful bulb vase info.
What is a Bulb Jar?
Basically, bulb glass vases are simply that – glass containers for forcing bulbs. The size and shape of bulb forcing jars depend primarily on the type of bulb you are attempting to force.
Hyacinth – Glass containers for forcing hyacinth bulbs can be simple, but they are often attractive containers that accentuate the beauty of the hyacinth blooms. Some hyacinth containers are collector’s items. Jars manufactured specifically for forcing hyacinth bulbs usually have a round, squatty bottom, a narrow midsection, and a rounded top that nestles the hyacinth bulb just above the water. Some jars are taller with a more slender shape.
Bulb forcing jars for hyacinth don’t have to be elaborate or expensive. For example, you can make a simple hyacinth jar with a standard canning jar. Just fill the jar with enough marbles or pebbles to hold the bulb above the water.
Paperwhites and crocus – Small bulbs, like paperwhites and crocus, are easy to grow without soil, and nearly any sturdy container will work, including bowls, vases, or canning jars. Just the fill bottom of the container with at least 4 inches (10 cm.) of pebbles, then arrange the bulbs on the pebbles so the base of the bulbs is just above the water, close enough that the roots will contact the water.
Tulips and daffodils – Larger bulbs, such as tulip and daffodil bulbs, are usually forced in wider, deeper containers that can accommodate three or four bulbs or more. Even a glass bowl is fine as long as it holds at least 4 inches (10 cm.) of marbles or pebbles. The pebbles support the bulbs and the base of the bulbs should be just above the water, near enough so the roots – but not the base of the bulbs – will contact the water.

Growing hyacinths in water (sometimes called forcing hyacinths) is a beautiful way to bring a touch of color and a gorgeous scent to your home. Although it's a somewhat lengthy process, growing the bulbs in water can help your hyacinth blooms last for weeks. Hyacinth bulbs produce fragrant blooms, ranging in color from light pinks to deep purples. Bulb vases, also known as hyacinth vases or forcing jars, hold the hyacinth bulb above water while giving the roots access to the space and water they need to grow.
Why choose tulips?
To begin with, why should you use tulips to create this ultimate look in your home? Well, to be honest, it’s because they are absolutely beautiful.
These springtime blooms are colorful, classy and wonderful to look at.
With the tulip being a common addition in Persian art and poetry due to its beauty and grace, they are often thought of as the perfect addition to any home environment, guaranteed to uplift the mood and ambiance.
A cheerful display of blooming tulips can revive any gardener’s spirits during the cold, wet winter months.
So, by planning and preparing your tulip bulbs you can be sure they will begin to make an appearance indoors long before they begin to bloom in your garden.
The process is pretty simple and requires a minimal amount of supplies, meaning the entire family can get involved in growing tulips in your glass jar.
This will guarantee that you will get a touch of spring in your home, before it even reaches your garden.
Step 2: Add Water
If you buy pre-chilled bulbs, remove them from their pot and rinse off the soil (if they've been potted), and snip off up to half of the roots' length. Fill the forcing vase to just below the cup where the bulb will rest. The bulb will reach for the water. You can also use water gel beads, which can make the vase look a little more attractive. Just set the bulb in the base, then fill in with water gel beads (1 teaspoon of dry beads soaked in 3 cups of water usually becomes about a quart of wet beads in about six hours). You might also need to add a little extra water to make sure it reaches the roots.
Now is the time of year my thoughts turn to hyacinth vases. I have started my hyacinth bulb forcing (see www.gardenwithindoors.org.uk) including using this recently purchased Menu vase. I did have a larger Menu vase in the past and regretted giving it away so pleased I saw this smaller version on ebay. I like the design with the metal insert sitting on the ledge. The ebay listing explained that the company is no longer in business but will still look out for old stock / used vases on ebay.

Tye Hyacinth Vases
While I'm organising my bulb forcing, it gives me a chance to look at them and photograph them. These are all my Tye vases (made by GP Tye in the 1850's - 1860's (I forget the exact dates)).
The vases are stamped on the base except the amethyst one which is exactly the same size as the others and appears to be the same aside from the stamp and I think it is a Tye vase, just unstamped. I think I've blogged about this before but I noticed it recently and it reminded me of it.
putting the vases together like this, one can see they are the same size
