The sun-loving Pin Oak Seedlings grow about 65 feet tall in acidic, moist soil. Especially when mature, this tree can handle some minor flooding, except when it is actively growing. It puts on male and female flowers. The male flowers grow on last year’s growth and are yellowish-green. These slim flowers have a cylinder shape and are usually between 1.25 and 4 inches long. Each male flower contains several stamens. Female flowers appear on short stalks that are less than 0.75 inches long. From one to four flowers can appear on each spike. These reddish-green flowers contain an ovary with three stigmata. The wind cross-pollinates the flowers.
The Leaves Of Pin Oak Seedlings
Alternate deciduous leaves grow on Pin Oak Seedlings, each capable of being up to 6 inches long. Each leaf has five to seven glossy green lobes with wide concave sinuses. In the autumn, the leaves turn russet red, bronze, or red.
Pin Oak Seedlings Acorns
Each female flower is replaced by an acorn, which takes two years to develop to its globoid shape and is usually between 0.33 and 0.5 inches long. About one-fourth of that will be covered in a tan cap while still maturing, which turns light reddish-brown when mature.
Pin Oak Seedlings Life Span
The Pin Oak Seedlings often live to be over 100 years old. Young trees have a pyramidal shape. When this tree, which usually grows up to 24 inches annually, matures, it becomes more oval. By the time it reaches its mature height after about 30 years, its shape becomes more oval. At that point, it can have a span of 25 to 45 feet.
