You can cross breed lilies by transferring pollen from the anther of one lily flower to the stigma of another lily flower.
This process, often called hybridization, is how gardeners create stunning new lily varieties with unique colors, shapes, and patterns.
If you’ve been wondering how to cross breed lilies successfully, you’re in the right place because it’s a rewarding project that any patient gardener can master.
While it takes a couple of years to see the final results, the thrill of watching a brand-new lily bloom that you created yourself is absolutely worth the wait.
In this post, we’ll walk through exactly how to cross breed lilies, from choosing parent plants to harvesting the seeds, so you can start your own breeding adventure.
How to Cross Breed Lilies: The Basics You Need to Know
To successfully cross breed lilies, you first need to understand the basic anatomy of the flower and the timing of the process.
Every lily flower has both male parts (anthers) and female parts (stigma), making it possible to cross breed lilies within the same flower or between two different plants.
However, to create a true hybrid, you’ll want to cross breed lilies from different parent plants, ideally from different species or cultivar groups.
When you cross breed lilies, the goal is to combine desirable traits like intense fragrance, unusual petal shapes, or robust stems into a single new offspring.
Let’s break down the key steps that will guide you through this fascinating process.
1. Choose Compatible Parent Lilies
The very first step to cross breed lilies is selecting two healthy, vigorous parent plants that are genetically compatible.
Not all lilies can cross breed lilies with each other easily, as different divisions like Asiatic, Oriental, and Trumpet hybrids have varying levels of compatibility.
To increase your success rate, you should try to cross breed lilies that belong to the same division or are known to be closely related.
For example, crossing two Asiatic lilies is much easier than trying to cross breed lilies from the Asiatic and Oriental groups, though it’s not impossible with careful technique.
Choose parents that are healthy, free of disease, and blooming at the same time so the pollen is fresh and viable.
Also, consider the traits you want in your new lily like a taller stem, a deeper red color, or earlier blooming.
This thoughtful selection is the foundation of how to cross breed lilies successfully.
2. Collect Pollen at the Right Time
Once your parent plants are blooming, you need to collect pollen at the precise moment when it’s mature and ready for transfer.
The anthers, which are the fuzzy tips covered in orange or brown powder, will release pollen when they are fully ripe.
To collect pollen for your cross, simply pinch off an anther with clean tweezers or your fingers once it has opened and shed its powdery coating.
If you want to cross breed lilies at a later time, you can store the anthers in a small paper envelope in the refrigerator for up to a week.
But for the best results, use fresh pollen the same day you collect it, as this gives you the highest chance that your cross breed will take.
Avoid touching the pollen with your bare hands, as the oils from your skin can reduce its viability.
3. Prepare the Female Flower
Before you transfer pollen, you must prepare the flower that will receive it, which acts as the female parent in your cross breed.
You should choose a flower that has just opened and whose stigma, the three-lobed structure in the center, is glossy and slightly sticky.
This stickiness is a sign that the stigma is receptive and ready to catch pollen.
To prevent accidental self-pollination, you’ll want to remove all the anthers from the female flower before they release their own pollen.
This process, called emasculation, ensures that only the pollen you introduce will be used to cross breed lilies.
Use small scissors or tweezers to carefully snip off each anther, then cover the female flower with a small paper bag to protect it from stray insects and wind-borne pollen.
This step is crucial if you want to maintain control over exactly how to cross breed lilies without unwanted surprises.
4. Transfer the Pollen to the Stigma
Now comes the most critical moment in your quest to cross breed lilies, which is the actual pollen transfer.
Take the anther you collected from the male parent and gently dab it directly onto the receptive stigma of the female flower.
You should aim to cover the entire sticky surface of the stigma with a generous layer of pollen.
Use a clean cotton swab or a small paintbrush if you prefer, as these tools can also help you cross breed lilies with precision.
Continue dabbing for about ten seconds to ensure adequate pollen grains are deposited.
After you finish, replace the paper bag over the female flower to keep other pollen out and to maintain a humid environment that helps the pollen germinate.
This single act of transfer is the essence of how to cross breed lilies, and it’s surprisingly quick once you get the hang of it.
5. Tag and Track Your Cross
To make your cross breed lilies project organized and meaningful, you absolutely must tag each pollinated flower with a label.
Write down the name of the female parent, the male parent, and the date you performed the cross.
You can use small plastic tags or even pieces of string with paper labels attached to the stem.
This record-keeping is vital because it can take several weeks for the seed pod to mature, and you’ll easily forget which cross was which.
When you cross breed lilies, the seed pod will swell at the base of the flower as the seeds develop.
Once this pod turns brown and begins to split open, usually six to eight weeks after pollination, it’s time to harvest your seeds.
Collect these seeds and store them in a cool, dry place until you’re ready to plant them.
Tips for Successful Lily Hybridization
Beyond the basic steps, there are a few professional tips that will dramatically improve your ability to cross breed lilies like a seasoned breeder.
Pay attention to these details, and you’ll see a much higher rate of success in your seed production.
1. Time Your Crosses for Morning Hours
The best time to cross breed lilies is in the early morning when the flowers are fresh and fully turgid with moisture.
Pollen is also most viable at this time, and the stigma is more receptive before the heat of the day dries it out.
Avoid crossing on rainy or very windy days, as water can wash the pollen away and wind can introduce unwanted pollen to your female flower.
2. Use Multiple Flowers for One Cross
Don’t rely on just one flower when you attempt to cross breed lilies, as not every pollination will result in a viable seed pod.
You should pollinate at least three to five flowers on the same female plant to increase your odds of getting good seeds.
This redundancy is a smart strategy that professional breeders use, and it will make your experience with how to cross breed lilies far more rewarding.
3. Practice Patience from Seed to Bloom
A crucial tip for anyone learning how to cross breed lilies is to manage your expectations regarding time.
After you harvest and plant your seeds, they will take about three to four years to grow into flowering bulbs.
This long timeline means you won’t see the results of your cross for quite a while, but that’s okay.
Keep your young plants in a dedicated nursery bed or pots, providing consistent moisture and fertilizer.
When that first bloom finally opens, you’ll be amazed at the new pattern or color that resulted from your careful work.
So, How Do You Cross Breed Lilies Successfully?
You cross breed lilies successfully by following a simple but precise sequence of pollen transfer, flower isolation, and patient seed growing.
From choosing the right parents to pollinating the stigma and tagging your crosses, each step plays a vital role in creating a new hybrid.
Whether you’re aiming for a novel color combination or a stronger stem, the process of how to cross breed lilies is both an art and a science.
So grab your tweezers, pick your favorite lilies, and start experimenting because the next great lily variety might just come from your own garden.
Remember to give it time, and enjoy every moment of the journey.
Happy breeding, and may your lilies be spectacular.
