Eutrochium fistulosum, commonly known as hollow Joe-Pye weed, is a tall and impressive perennial plant that can reach heights of 4-7 feet. Its striking feature is its erect and clump-forming growth habit, which adds a dramatic element to any garden or landscape.
One of the key identifiers of Eutrochium fistulosum is its dark green lance-shaped leaves. These leaves are typically large, measuring up to 12 inches in length. They have a coarse texture and are serrated along the edges, giving them a slightly jagged appearance. The leaves are arranged in whorls of 4-7, with 6 being the most common number of leaves in each whorl. This unique leaf arrangement adds to the visual appeal of the plant.
The stems of Eutrochium fistulosum are another distinguishing feature. They are sturdy and green, with a hollow center. This hollowness can be observed by gently pressing on the stem and feeling for any give or lack of solidity. The hollow stems not only contribute to the plant’s overall structure but also provide an interesting characteristic to observe.
When identifying Eutrochium fistulosum, it is important to consider its overall growth habit. This perennial tends to form clumps, with multiple stems emerging from a single base. The clumps can gradually expand over time, creating a dense and impressive display. Observing the plant’s growth pattern can help confirm its identity.
In terms of flowering, Eutrochium fistulosum produces numerous small, pinkish-purple flowers that form in dense clusters at the top of the stems. These flowers are attractive to pollinators, particularly butterflies and bees, adding to the plant’s ecological value.
To summarize the key characteristics of Eutrochium fistulosum:
– Tall and clump-forming perennial, reaching heights of 4-7 feet.
– Dark green lance-shaped leaves, coarsely serrated, and arranged in whorls of 4-7 (often 6).
