First of all: Growing calla lilies from seeds is time-consuming. Above all, it takes several years for the plants grown in this way to produce their first flowers. It is only worth sowing indoor calla lilies if they are particularly beautiful varieties that are not otherwise available.
How to grow calla lilies from seeds?
To grow calla lilies from seeds, harvest or buy the seeds, sow them in clean potting soil in spring, keep them evenly moist and warm (20-22 degrees Celsius). As soon as the seedlings are large enough, separate them.
Growing calla lilies from seeds
- Cut off seeds
- Hang to dry
- Shaking out seeds
- Store in a dry and dark place until spring
- Sow from January
Harvest seeds yourself or buy them
You can only get germinable seeds from your indoor calla flower if it has been pollinated. Either use a brush or leave the blooming calla on the terrace for a while.
The seeds are located on a small cob within the colored bract, often referred to as the flower.
When the flower has finished blooming, cut off the bulb and hang or place it in a dry place. The small, round or egg-shaped seeds depending on the variety can then be easily shaken out and stored in a dark place until sowing.
Buy or exchange seeds in specialist stores
You can also get seeds for the indoor calla from specialist garden shops. Here you can be sure that the seeds will actually germinate.
There are exchange circles among flower lovers in which members exchange seeds for particularly beautiful house plants.
Sowing calla lilies
Prepare a planting bowl (€35.00 on Amazon) with very clean potting soil. Sow the seeds as thinly as possible and dust some soil over them. Place the plant bowl in a location that is 20 - 22 degrees and keep it moist.
It takes a while until the first seedlings appear. As soon as they are big enough, they are separated and planted in their own small pots. Make sure that the soil must be free of bacteria and fungal spores.
Even if the indoor calla grown from seeds will not produce flowers in the first few years, you need to keep it moist until August and let it dry out during the rest period.
Tips & Tricks
Instead of growing your favorite calla from seeds, you can also propagate it by dividing the tubers. This requires significantly less effort and the new plants usually bloom the following year.
