Gomphrena Seeds
Globe Amaranth
Gophrenas are used in annual beds and borders. In masses, the round flower heads produce an interesting texture, and their bright colors last late into the season. Their low stature makes them well suited for edging around taller plantings.
It tolerates poor soils, heat and drought, and was once a favorite in British gardens. It is a true "everlasting" and one of the best flowers you can grow for dried arrangements. As an added bonus, it attracts butterflies.

How to Grow Gomphrena Seeds
Germination Media
Use a well-drained, disease-free media with a pH
range of 5.8 to 6.2, and EC less than 0.75mS/cm (2:1
extraction).
Sowing
Cover the seed with vermiculite lightly as they need light for germination.
Stage 1 Germination takes approximately 2 to 5
days.
- Seeds should be soaked in water for a day or two before planting.
- Germination temperature: 68 to 75�F (20 to 24�C).
- Light: Light is required for germination.
- Media Moisture: Keep the media medium wet (level
4) during germination.
- Relative Humidity: Maintain 95 to 97% relative
humidity until cotyledons emerge. Avoid excess
humidity later-on in the plug production, as this will
create conditions favorable for disease incidence.
Stage 2
- Temperature: 72�F (22�C) days; 68�F (20�C) nights.
- Light: Can be up to 2,500 f.c. during
Stages 2 and 3.
- Media Moisture: Keep the media medium (level 3) to
medium wet (level 4) during Stage 2.
- Fertilizer: Apply fertilizer at rate 1 (less than 100 ppm
N/less than 0.7 mS/cm EC) with a nitrate-form fertilizer
with low phosphorous. Maintain a media pH of 5.8 to
6.2 and EC at 0.5 to 0.7 mS/cm (1:2 extraction).
Stage 3
- Temperature: 72�F (22�C) days; 68�F (20�C) nights.
- Light: Can be up to 5,000 f.c. while
maintaining temperatures.
- Media Moisture: Moisture level can be reduced to
medium to medium dry (level 3 to 2). Do not allow the
seedlings to wilt.
- Fertilizer: Increase the fertilizer rate to 2 (100 to 175
ppm N/0.7 to 1.2 mS/cm EC). Maintain a media pH of
5.8 to 6.2 and EC at 0.7 to 1.0 mS/cm (1:2 extraction).
Stage 4
- Temperature: 68�F (20�C) days; 64�F (18�C) nights.
- Light: Can be up to 5,000 f.c. while
maintaining temperatures.
- Media Moisture: Moisture level can be reduced to
medium to medium dry (level 3 to 2). Do not allow the
seedlings to wilt.
- Fertilizer: Keep the fertilizer rate to 2 (100 to 175 ppm
N/0.7 to 1.2 mS/cm EC). Maintain a media pH of 5.8 to
6.2 and EC at 0.7 to 1.0 mS/cm (1:2 extraction).
Growing On to Finish
- Media
Use a well-drained, disease-free soil less media with a
pH of 5.5 to 6.2 and an EC of 0.75 mmhos/cm.
- Temperature
- Night: 63� to 66�F (17� to 19�C)
- Day: 65 to 75�F (18 to 25�C)
Gomphrena can be grown under moderate to cooler
temperature conditions (50�F/10�C minimum);
however, crop time increases.
Light
Light level should be as high as possible while
maintaining proper temperature
Irrigation
Avoid both excessive watering and drought.
Many gardeners set out 6-8 week old seedlings for a head start on the season.
