Macrocentra Or just a guess try maybe 'Red Ferrari'… there are so many red amaryllis in the market today…depending on where they originate. North or South hemispheres. North are bulbs from the Netherlands bloom Nov. Dec -Feb March cold temp seasons. Southern hemisphere grown bulbs from Peru/Africa bloom later in the season June - August during warmer temperatures , depending on zones. I'm guessing since your blooming amaryllis is in august sept… could be a bulb originated from the southern hemisphere. Also plus very few blooms with the long anther that set low in the bloom position . It is a huge gorgeous bloom. What a beautiful statement this time of year.
Not familiar with orange blooms… in my opinion any color amaryllis is always spectacular any time of year.
Apple Blossom blooms are spectacular always a crowd pleazer… one of my favorites.
All of my amaryllis are dormant now. Some from both north and south hemispheres,
By Oct. I will repot them all and have some lovely blooms for the Holidays.
