Calla lilies can be grown from seed, but it requires patience and specific conditions to successfully germinate and develop healthy plants.
If you’re wondering whether calla lilies can be grown from seed, the short answer is yes—they definitely can, but growing them from seed is quite different and more time-consuming compared to growing from rhizomes or bulbs.
In this post, we will explore how calla lilies can be grown from seed, what you need to know about growing calla lilies from seed, how to successfully germinate their seeds, and tips for nurturing them to bloom.
Let’s dive into everything you need to know about growing calla lilies from seed.
Why Calla Lilies Can Be Grown From Seed
Calla lilies can be grown from seed because their flowers produce seeds that, when properly handled, can grow into new plants.
Unlike some plants that are sterile or hybridized and do not produce viable seeds, calla lilies naturally produce seeds that retain the ability to sprout.
Growing calla lilies from seed is a simple concept: collect the seeds when the flowers fade, plant them in the right medium, and nurture them through germination and early growth.
1. Calla Lilies Are Seed-Producing Plants
Calla lilies produce seed pods after their flowers fade.
Once pollinated, the flowers develop seed pods filled with small, hard seeds that can be collected for planting.
This natural seed production enables gardeners to propagate calla lilies sexually, which can sometimes lead to new variations and colors.
2. Seeds Provide Genetic Diversity
Growing calla lilies from seed means the new plants will have genetic variation.
This is because the seeds result from sexual reproduction, unlike bulbs or rhizomes, which are clones of the parent plant.
For those interested in breeding or experimenting with new colors and varieties, growing calla lilies from seed is an exciting option.
3. Seeds Offer a Low-Cost Propagation Method
Starting calla lilies from seed can be more economical than purchasing new rhizomes or bulbs every year.
If you already have mature plants producing seeds, you can collect those seeds and grow your own new calla lilies without spending extra money.
This makes growing calla lilies from seed an appealing option for budget-conscious gardeners.
How to Grow Calla Lilies From Seed Successfully
Knowing that calla lilies can be grown from seed is just the first step; the key to success lies in understanding the best way to germinate and care for these seeds.
Growing calla lilies from seed takes patience because it can take several weeks to germinate and even longer for the plants to mature and bloom.
1. Seed Collection and Preparation
To grow calla lilies from seed, you first need to harvest the seeds at the right time.
Once the flowers are pollinated and the seed pods start to dry and turn brown, you can carefully collect them before they crack open.
Extract the seeds from the pods and let them air dry completely before storage or planting.
2. Seed Soaking to Speed Germination
Calla lily seeds have a hard outer coat that can slow down germination.
Soaking the seeds in warm water for 24 to 48 hours softens the seed coat, which helps encourage faster and more successful germination.
Change the water every 12 hours to avoid stagnation and potential mold.
3. Selecting the Right Growing Medium
Calla lily seeds need a well-draining, light seed-starting mix to germinate successfully.
A blend of peat moss, perlite, and vermiculite works well to provide moisture retention without waterlogging the seeds.
Fill a seed tray or small pots with the mix and moisten it before sowing the seeds on the surface.
4. Sowing Seeds Correctly
Plant calla lily seeds about ½ inch deep in the prepared soil.
Cover them lightly with soil, as burying them too deeply can hinder germination.
Keep the soil consistently moist but not soggy throughout the germination period.
5. Maintaining Ideal Germination Conditions
Calla lily seeds germinate best in warm temperatures ranging between 70°F to 75°F (21°C to 24°C).
Using a heat mat under the seed trays can help maintain a consistent temperature for faster germination.
Make sure to keep the seed-starting mix moist but avoid waterlogging, which can rot the seeds.
6. Patience During Germination
Calla lily seeds can take anywhere from 14 days to 30 days or longer to germinate.
Don’t give up if you don’t see sprouts immediately; some seeds just take time.
Keep monitoring moisture and temperature and be patient for the young seedlings to emerge.
Tips for Growing Healthy Calla Lilies From Seed to Bloom
Once your calla lily seeds germinate, there are some essential steps to ensure those seedlings grow into flowering plants.
1. Gradual Exposure to Sunlight
Young calla lily seedlings need bright, indirect light to thrive.
Direct sunlight can be too harsh and scorch delicate leaves.
Gradually introduce your plants to increasing sunlight as they mature to prepare them for outdoor conditions.
2. Transplanting Seedlings Properly
When seedlings get their first true leaves and look strong enough, transplant them into individual pots or larger containers.
Use well-draining potting soil rich in organic matter to promote healthy growth.
Ensure good drainage to prevent root rot.
3. Watering and Fertilization
Calla lilies prefer consistently moist soil but don’t like sitting in waterlogged conditions.
Water them regularly but allow the top inch of soil to dry out between waterings.
Feed seedlings with a balanced liquid fertilizer every two to three weeks to encourage healthy foliage and eventual flowering.
4. Providing Adequate Temperature and Humidity
Calla lilies thrive in warm, humid conditions.
Maintain temperatures between 65°F and 80°F (18°C to 27°C) and moderate humidity levels to keep plants happy.
Avoid cold drafts or sudden temperature fluctuations, which can stress the plants.
5. Patience Until First Bloom
Calla lilies grown from seed can take up to two or even three years before they flower.
While this requires patience, the reward of watching your plants bloom after growing them yourself from seed is satisfying.
Keep looking after your plants through their growth stages and enjoy their elegant flowers when they appear.
Common Challenges When Growing Calla Lilies From Seed
Although calla lilies can be grown from seed, you should be aware of the common challenges to avoid disappointment.
1. Slow Germination
Calla lily seeds can be slow to germinate and sometimes unpredictable.
The hard seed coat and need for warmth mean you must be patient and maintain consistent conditions.
Inconsistent moisture or temperature often leads to failed germination attempts.
2. Seedling Vulnerability
Young calla lily seedlings are delicate and prone to damping-off disease if overwatered or kept in poor air circulation.
Prevent problems by using sterile seed-starting mix and spacing seedlings properly to allow airflow.
Avoid overwatering and remove any moldy or rotting plants immediately.
3. Long Time To Flower
One of the biggest challenges is that calla lilies grown from seed take much longer to produce flowers compared to bulbs or rhizomes.
Sometimes it can take 18 months to three years to see blooms, which requires patience and dedication.
If you want quick results, growing from bulbs might be a better method.
4. Genetic Variations in Seed-Grown Plants
Because seed-grown calla lilies come from sexual reproduction, the offspring may have different flower colors, shapes, or sizes than the parent plant.
While this can be a fun way to discover new varieties, it also means you might not get the exact look you expected.
If you want identical plants, bulbs or rhizomes are preferable.
So, Can Calla Lilies Be Grown From Seed?
Calla lilies can be grown from seed, and doing so offers the chance to propagate new plants, explore unique variations, and save money on buying new rhizomes.
Growing calla lilies from seed requires patience, proper seed preparation like soaking, consistent warmth and moisture, and careful nurturing of seedlings.
Although it takes longer for seed-grown calla lilies to flower compared to bulbs, the process can be very rewarding for gardeners who enjoy propagation and experimentation.
With the right care—choosing a good seed-starting mix, keeping temperatures warm, avoiding overwatering, and providing bright indirect light—you can successfully grow calla lilies from seed and enjoy their elegant blooms in time.
If you’re ready for some patience and a bit of practice, starting calla lilies from seed is a wonderful gardening project that can add diversity and charm to your garden.
So yes, can calla lilies be grown from seed? Absolutely, with proper attention and care, your calla lily seeds can grow into beautiful flowering plants.
