Amaranth Seeds

About Amaranthus

Amaranth is an easy to grow summer bloomer that's great for cut flowers. These hanging blooms attract birds with their seedy heads and make beautiful backdrops or edge pieces for your flower garden.

Where to Plant Amaranthus Seeds

Amaranth needs full sun and can be grown in almost any well-drained soil besides dense clay.

How to Plant Amaranthus Seeds

Plant your seeds about 10-12 inches apart and cover lightly with soil. They will germinate within 3-4 days if the temperatures are between 60-90 degrees F. When moving your seeds outside, sow them 1.5 to 2 feet apart. Amaranth is drought and heat resistant, so it is only necessary to water once or twice a week during dry periods. For taller plants, add fertilizer once or twice a year or add compost. Amaranth grows between 4 and 6 feet tall but with particularly rich soil with plenty of nitrogen and phosphorous, the plants can get to around 8 feet!

How to Care for Amaranthus

Amaranth will flower until the first hard frost, so there will be plenty of seeds to harvest! Seeds from the flowers are usually ready for harvest after 3 months. To harvest, shake the flower heads and catch the falling seeds.

When to Plant Amaranthus Seeds

Amaranth can be planted inside or outside in the Spring, but we would recommend starting the seeds indoors 6-8 weeks before your last frost. If you decide to plant outside, wait until the soil is warm.
