How to Grow Amaryllis from Seed

Amaryllis plants display large, colorful, trumpet-shaped flowers on long, slender stems framed by glossy green leaves. Flower colors can range from pure white to yellows, oranges, pinks or reds and are often multicolored with a variety of patterns. While Amaryllis are usually propagated by separating new bulbs from older plants, they can also be grown from seed. Amaryllis seeds collected from pods or purchased online or from seed catalogs can be germinated relatively easily.

Feel each amaryllis seed for a bump in the middle. This indicates the seed is most likely viable.

Float the amaryllis seeds in a bowl of water and put the bowl in a warm, sunny place. Watch for the seeds to sprout in the water in about 4 weeks.

Prepare a mixture of equal amounts of potting soil and coarse sand. Fill planting flats with the soil mixture and water to moisten the soil.

Plant one of the sprouted seeds, carefully, in each cell in the flat. Ensure that the bump in the seed and any roots beginning to form are covered lightly with soil and any green shoot is above the soil level. Water the seeds lightly. Place the flat in a warm, bright area. Water occasionally to keep the soil moist, but not wet

As the seedlings mature, transplant them to 1-gallon containers to grow out. Continue to water the amaryllis plants, lightly.

Plant outdoors in spring or summer, or grow indoors as a house plant at any time.

Raise Amaryllis From Seed

Gather amaryllis seeds after the flowers fade and ripen into capsules. Wait until the seed capsules turn pale beige or yellow and begin to split open, exposing the shiny black seeds. Discard any damaged, moldy or off-colored seeds since they are likely inviable. Soak the amaryllis seeds in a bowl of water overnight to determine which are viable. Sow those that sink to the bottom. Prepare a growing container for each amaryllis seed. Fill 3.5-inch starter pots with a mixture of half thoroughly rinsed coarse sand and half milled peat. Sow one seed in each pot at a depth of 1/4 inch. Add water whenever it feels mostly dry on the surface. Water until the top 2 inches feel moderately moist. Feed the seedlings with general-purpose fertilizer diluted to one-quarter strength once three mature leaves emerge.
