Hyacinth Seeds: Harvesting, Propagation & Buying Guide

Hyacinth flower can be grown from seeds.

Did you know Hyacinths are decorative flowering plants that go back to medieval times and are often used in Persian New Year?

This beautiful plant offers variedly colored and fragrant blossoms yearly, which symbolize peace, beauty, and pride.

However, they are rarely grown from seeds because it may take years of dedication but is not impossible.

Harvest Hyacinth seeds from mature flower pods in April-September; dry for a fortnight and soak 24 hours before laying on a paper towel and refrigeration, then grow in a germination tray at 70-75°F and wait for 1-6 months.

Hyacinths are rarely grown from seeds but from bulbs.

Voila! The Hyacinth seeds will begin germinating and are ready to transplant into individual containers.

Nevertheless, prepare to face the backlash as about half of the seeds will fail to sprout for many reasons.

Read on to figure out how to prepare Hyacinth seeds so you can minimize the loss during germination and yield beautiful mature Hyacinths.

Hyacinth Seeds Overview

Hyacinth (Hyacinthus orientalis) is a small spring-blooming perennial plant from the eastern Mediterranean plains.

They came around 1560 from Turkey, Syria, and Lebanon to Europe, but it was much later that they were introduced as houseplants and only owned by wealthy plant lovers.

The Hyacinth species you usually see in the garden or shops are the cultivars of the wild Hyacinth plant.

These cultivars include single Hyacinth, double Hyacinth, and multiflora Hyacinth, offering vividly colorful blossoms ranging from white, cream, pink, rose, cobalt blue, deep purple, and wine red.

The great thing about Hyacinth cultivars is that they exhibit the best forms of colors and intense fragrance and even proliferate in homes or outdoors with the least effort.

Nevertheless, growing them from seeds can become challenging because they are usually produced from bulbs.

Most Hyacinths grown from the seeds fail before they can even be germinated.

You heard it right! Successfully propagating Hyacinth seeds would require harvesting and maturing seeds, the proper preparation, and a conducive growing environment.

Here is a brief guide about Hyacinth seeds.

One way to sprout Hyacinth seeds is to treat them and place them in a plastic bag in a refrigerator. Once ready, you can germinate them in a growing medium.

Otherwise, plant them directly on the growing medium and wait until they successfully germinate.

The Hyacinth flowers will retain their color depending on your chosen cultivar, but you must wait years before they can even mature.

Like propagating Gardenia seeds, Hyacinth seed germination tends to be sporadic (occurring at irregular intervals).

How to Collect Hyacinth Seeds?

Collecting Hyacinth seeds is relatively simple; you only need to wait for the flowers to mature before you can retract the seed or flower pod.

These plants bloom in mid-spring filling the garden with lovely fragrance, indicating that the seed is also growing.

They require an ideal growing condition, including full sun and optimal darkness, loose and well-drained soil, weekly watering, and temperature over 60°F to blossom.

Hyacinth will begin producing seed pods when it starts blossoming. Once the flower spikes appear, they put energy into creating seeds.

Growers who often nib the flowers in mid-spring will likely fail to get Hyacinth seed pods. Therefore, be wary about pruning the flowers.

Remember, the plant does not self-pollinate, requiring help from garden bugs; hence, only the outdoor grown Hyacinths are likely to produce seeds.

Steps to Harvest Gardenia Seeds

As previously mentioned, you must let the Hyacinth flower bloom and avoid pruning to get seed pods.

Look for brown-colored pods in late summer or early autumn that indicate they are matured, but leave the pods be if they are still green and fleshy.

Simply pick them from the plant and split the pod into two to retrieve black seeds. Carefully gather these seeds in a Ziploc bag so you can use them later. 

Storing these seeds is relatively simple. Start soaking them in fresh water for 24 hours and tap drying using a paper towel. Place another paper towel over before putting them in a refrigerator.

This will ensure the seeds stay healthy for future use as well as sprout before they are germinated.

Note: Wait about 2-3 months to let the seeds sprout.

Steps to Germinate Hyacinth Seeds

Remember, germinating Hyacinth seeds can be difficult because most seeds fail to sprout.

Not all Hyacinth seeds will pass the stratification; therefore, collect as many seeds as possible to increase the likelihood.

Moreover, the germination process is more sporadic and may take well over 4 to 5 years for the seedling to mature into a flower-bearing plant.

Therefore, you can cut the process short by propagating the extracted bulb from the healthy Hyacinth plant.

If you are determined to germinate Hyacinth seeds at home, here is a detailed process.

Materials Required

Here is the list of materials required for successful germination.

Materials RequiredPurpose
SeedsFor germinating
Seed Starter MixFor growing the seeds
Seed TrayPotting Medium
Gloves
For safety
Plastic bag or sheetTo maintain humidity and temperature for the seeds
2-3" PotCeramic, Clay, or Plastic pot with drainage holes for transplantation

Step 1: Prepare the Seed

Freshly extracted Hyacinth seeds need to be prepared before they can be germinated.

  • Known as stratification, the process involves soaking the seeds in lukewarm water for 24 hours to swell their outer layer so the sprout can begin.
  • Retrieve and place them on a paper towel to soak all the remaining water.
  • Immediately place another paper towel over it and keep it in the refrigerator but freezer. The temperature should stay above sub-zero.
  • Check for new green sprouts from the seeds, which would take about 2 to 3 months.

You can continue sprouting the seeds throughout the winter to germinate them in early spring.

Check whether the store brought Hyacinth seeds that are already sprouting. Otherwise, you must soak them in water and store them in the refrigerator to induce sprouting.

Step 2: Germinate the Seed

Start preparing the starter mix, which you can quickly make at home or buy in a supermarket.

  • The seed starter mix is similar to other seed starter mixes. Mix an equal part of peat moss and perlite.
  • Moisten the mix before placing it in the germination kit.
  • Mix about 4 grams of seeds with a small amount of sand to make them easier to sow.
  • Sprinkle the seed and sand mixture over the germination kit and gently press them inside.
  • Add up to 2 to 3 seeds per section and about 1 to 2 inches apart from each other.
  • Afterward, induce a mini greenhouse by covering the tray with a clear plastic bag or cover and placed under LED grow light for 10 to 12 hours.
  • Ensure the temperature stays between 70 to 80°F along with an average of 60% humidity to boost the germination process.
  • Consider slipping the heating pad under the tray for seedlings grown in a cold climate to keep them warm.

Voila! Your Hyacinth seeds are germinated within 5 to 6 months.

Step 3: Transplant the Seedlings

The next step involves transplanting the seedlings into an individual pot.

The seedling will have at least 1 to 2 tiny leaves sprouting out of the mix. It indicates that they are ready to be moved.

  • Start preparing the potting mix containing organic and inorganic matters like potting soil, perlite, and orchid bark.
  • Gently turn the germination tray and slide the seedling out.
  • Ensure to keep the mix well-draining. They are not particular about soil pH.
  • Take a 3 to 5 inches clay or terracotta pot and fill it with the prepared mix.
  • Moisten the mix before placing the seedlings into the pot, and then scoop the mixture on and around the seedlings.
  • Move it to a sunny location, such as outdoors; if it is spring, continue with the regular care.
  • These plants can grow well in cold climates like USDA Zone 4 to 8; provide full sun to ensure healthy growth.

The seedlings will not sprout for the first year as they store energy to develop the bulb or root.

When the care and maintenance are ideal and regular, the plant will grow many inches taller and produce green foliage and magnificent flowers.

However, it can take up to six years before some Hyacinth varieties will even develop a flower when growing hyacinth from seed.

Care Tips for Hyacinth Seeds After Germination

Here is a brief guide about caring for Hyacinth seedlings after germination.

CareSpecification
Sunlight1. Provide at least 6-8 hours of full sunlight or partial shade.
2. Avoid low-light areas that may prevent healthy blossoms.
3. When grown indoors, consider providing at least 12-14 hours of lighting
Temperature1. Provide 60°F or above temperature during spring and summer.
2. The saplings prefer a consistent 65°F during the day and 60°F at night.
3. They are quite picky about high temperatures, so avoid growing them in USDA zones 10 or above.
Humidity1. Hyacinth is not too picky about humidity as it prefers a combination of low to moderate temperatures.
2. Provide a relative humidity of around 50% at all times.
3. Regular misting will help achieve moderate humidity for outdoor grown Hyacinth.
Watering1. Do not overwater Hyacinth, they hate staying with "wet feet"
2. Let the top 2-3" of soil dry out between watering.
3. Provide 1/2 inch of water per week in the growing season to the potted plant.
4. Plant grown in garden will require at least 3x more amount of watering.
4. Water every 20-25 days in the fall and winter
Fertilization1. Provide a scant handful of balanced dry garden fertilizer in spring.
2. Use fertilizer with NPK 10-10-10 to feed the bulbs for healthier growth.
3. Avoid fertilizing immediately after blossoming to avoid problems.

Conclusion

Early growers believed that Hyacinth symbolizes the flower of the sun god Apollo and advocates peace and beauty.

They were not wrong because this plant is widely used for decorating venues and events.

Carefully harvest, stratify, and germinate Hyacinth seeds to ensure most of them grow further.

However, be patient and continue the regular care to keep your Hyacinth on the right track until they blossom in the next 4-5 years.
