Vasculus

Vasculus is a genus of flowering plants in the family Asteraceae, commonly known as asters. The genus is native to North and South America, with a significant diversity of species found in various habitats ranging from grasslands to forests. Vasculus species are typically herbaceous perennials, characterized by their daisy-like flower heads. These heads usually consist of a central disk of florets surrounded by ray florets, which are often vibrantly colored in shades of purple, blue, pink, and white.

The leaves of Vasculus plants are generally simple and arranged alternately along the stem, though their shape and size can vary considerably between species. Some species have smooth leaf margins, while others are toothed or lobed. The root system is often fibrous or can form rhizomes, allowing for vegetative propagation.

Ecologically, Vasculus plays a role in supporting various insect pollinators, including bees and butterflies, making them valuable components of native plant communities and garden landscapes. Several species are cultivated for their ornamental value, appreciated for their late-season blooms that add color to gardens when many other plants have finished flowering. The genus name itself is derived from the Latin word for "little vessel," possibly referring to the shape of its achenes or seeds. Conservation statuses of Vasculus species vary, with some being widespread and common, while others are rare or endangered due to habitat loss and other environmental pressures.
