Red Maples In Bloom

4-20-17 red maple male flowers IMG_2938

Red Maples (Acer rubrum) are celebrated in the fall for their vibrant colors, but they produce equally vibrant reds and yellows in early spring when they are flowering. Most Red Maples have dense clusters of either male flowers or female flowers (dioecious), although some have both male and female flowers (monoecious). Under certain conditions, a Red Maple tree can sometimes switch from male to female, male to both male and female (hermaphroditic), and hermaphroditic to female.

The showier male, or staminate, flowers contain between four and twelve stamens, with long, slender filaments and red (young) or yellow (mature) anthers at their tips. Both red sepals and petals can be seen at the base of the stamens.  A staminate Red Maple in full bloom is a blaze of gold and red. (Photo: mature staminate Red Maple flowers)

  2. Spectacular! I love seeing red maples in the spring, but mostly see the flowers after they’ve fallen, when they’re a bit wilty. This photo is lovely. And thanks for yet another interesting lesson in the details of it all…

    I’ve always enjoyed the blush of red maple blooms across the landscape, but this lovely photo makes me realize I’ve never examined the blossoms up close. Thanks for opening my eyes to them! Now I need to go find a low-hanging branch.

  4. Great photo, Mary. I love seeing the rosy hues on the hillsides and today, I noted the chartreuse maple flowers are starting to bloom – how I love that color!
