Are you growing amaranthus in Hawaii, but don’t know when they’ll bloom?
Getting your Amaranthus to bloom is not as easy as it seems.

When Do Amaranthus Bloom in Hawaii?
As you may have already guessed, there are two main factors that determine when amaranthus will bloom: where your amaranthus are planted & weather (time).
Bloom Time Depends on Where Your Amaranthus Are Planted!!!
When your amaranthus will bloom will depend on exactly where it is planted in your yard or garden
In general, expect the following:
- If a amaranthus is planted in an area of your yard that receives full sun it will bloom around the same time every year or up to two weeks early due to warm weather and extra sunlight.
- If a amaranthus is planted in an area of your yard that received partial sun it will bloom around the same time every year.
- If a amaranthus is planted in an area of your yard that receives shade and is not protected from wind or rain it will bloom anywhere from 1 to 3 weeks later than its average time.
