Summary
Eryngium vesiculosum, commonly known as Prickly Rattlesnake or Bubble Eryngo, is a perennial herb native to coastal plains and sandhills in Australia. It typically grows to a height of 1-3 feet (0.3-0.9 meters) and a width of 1-2 feet (0.3-0.6 meters). This plant is characterized by its spiny, silver-blue foliage and spherical, steel-blue flower heads that bloom in the summer, providing a unique texture and color contrast in the garden. The flowers are quite showy and attract pollinators such as bees and butterflies.
Prickly Rattlesnake is valued for its drought tolerance and its ability to thrive in poor, sandy soils, making it an excellent choice for xeriscaping and naturalistic plantings. It is often used in rock gardens, coastal landscapes, and as an accent in borders due to its striking appearance. Eryngium vesiculosum requires full sun to maintain its best form and color and prefers well-drained soils, although it can adapt to clay, loam, or sandy soils with medium moisture levels. While generally low-maintenance, it can be susceptible to root rot if overwatered or planted in poorly drained soils.CC BY-SA 4.0
