    5-8 feet? More like 10-14 feet! Super easy, I started mine in April, indoors in 16oz cups, let them grow to about 8 inches tall then sowed directly in the ground. Grew like a weed. A little shot of water from the hose every few days and a light sprinkle of 12-12-12 fertilizer once or twice a month was all the care they needed.

    Amazing to watch grow. Flower heads nearly a foot across. Dozens of bees hard at work on each flower on any given day. I will plant dozens next year to attract more bees to my vegetable garden area! Just be mindful of the shadow they cast, don’t plant them in a way they will block out the sun for things like tomatoes and peppers.

    Grows to 10 feet or higher, even when grown close to each other (2 plants per square feet). They provide great shade for plants below and thrive in the heat of Texas. Mine are just beginning to flower. I hope to get tons of seeds ๐Ÿ™‚

    These did not disappoint! My friends, family, and neighbors couldn’t believe how tall these got (peeked passed out addition’s roof)! Each easily measured 9.5-11ft tall (100% germination – grew 8 of them, about a foot apart). Unfortunately, the squirrels got to the seeds before we could! There’s always next season! A must try for sure! ๐Ÿ™‚
