Growing Fatsia japonica from seed

Fatsia japonica, also known as Japanese aralia or glossy-leaf paper plant, is a striking evergreen shrub native to Japan. It is a popular choice for gardens and indoor spaces due to its large, glossy, palmate leaves and architectural growth habit. While Fatsia japonica can be propagated through division and cuttings, growing it from seed can be a rewarding and cost-effective way to expand your plant collection. In this guide, we will explore the steps to successfully grow Fatsia japonica from seed.

Collecting seeds

The first step in growing Fatsia japonica from seed is to collect mature seeds from a healthy parent plant. The seeds are typically produced in the fall after the plant has flowered. Look for seed heads that have turned brown and started to dry out. Carefully remove the seeds from the seed heads and allow them to air dry for a few days before storing them in a cool, dry place until you are ready to plant.

Preparing the soil

Fatsia japonica seeds prefer a rich, well-draining potting mix. You can create a suitable mix by combining equal parts of peat moss, perlite, and compost. Fill a seed tray or small pots with the potting mix, leaving a little space at the top for the seeds.

Planting the seeds

Plant the Fatsia japonica seeds about 1/4 inch deep in the prepared potting mix. Gently water the soil to ensure it is evenly moist but not waterlogged. Place the seed tray or pots in a warm, bright location, but out of direct sunlight.


Keep the soil consistently moist but not soggy during the germination period. Fatsia japonica seeds typically germinate within 2-4 weeks, but it can take longer, so be patient. Once the seeds have germinated, you can move the young seedlings to a slightly cooler location with indirect sunlight.


Once the seedlings have developed several sets of true leaves, they can be transplanted into individual pots filled with a well-draining potting mix. Be gentle when handling the seedlings to avoid damaging the roots. Water the newly transplanted seedlings and place them in a location with bright, indirect light.

Care and maintenance

Provide your Fatsia japonica seedlings with consistent moisture, but avoid overwatering, as this can lead to root rot. Fertilize the seedlings with a balanced liquid fertilizer every 4-6 weeks during the growing season to promote healthy growth. Keep an eye out for pests such as spider mites or aphids and treat them promptly if necessary.

Hardening off

Before planting your Fatsia japonica seedlings outdoors, it is essential to harden them off to acclimate them to the outdoor conditions. Gradually expose the seedlings to increasing amounts of sunlight and outdoor temperatures over a period of 7-10 days. This process will help prevent transplant shock and ensure the seedlings thrive once planted in the garden.

Planting in the garden

Choose a planting location for your Fatsia japonica that receives partial shade to full shade and has well-draining soil. Dig a hole slightly larger than the root ball of the plant and gently loosen the roots before placing it in the hole. Backfill the hole with soil, water thoroughly, and mulch around the base of the plant to help retain moisture.


Growing Fatsia japonica from seed can be a rewarding experience that allows you to witness the plant's growth from a tiny seed to a mature shrub. By following the steps outlined in this guide, you can successfully propagate Fatsia japonica and enjoy its striking foliage in your garden or indoor space.
