Welcome to our comprehensive guide on the spiked water-milfoil (Myriophyllum spicatum), a fascinating aquatic plant species that can be found in various bodies of water. In this article, we will explore the key facts about this plant, including its appearance, habitat, and growth habits.
Appearance: Spiked water-milfoil is a perennial plant with long stems that can reach up to three meters in length. The leaves are finely dissected and arranged in whorls around the stem, giving the plant a unique feathery appearance. One distinguishing characteristic of this species is its spiked inflorescence, which consists of small flowers densely packed along the stem.
Habitat: Spiked water-milfoil is a highly adaptable plant that can thrive in a wide range of aquatic habitats. It can be found in both freshwater and brackish water environments, including lakes, ponds, rivers, and estuaries. This species prefers areas with slow-moving or stagnant water, as it requires ample sunlight for photosynthesis.

Characteristics of Spiked Water-Milfoil
Spiked Water-Milfoil (Myriophyllum spicatum) is an aquatic plant that belongs to the Haloragaceae family. It is often found in freshwater lakes, ponds, and slow-moving streams. This submerged perennial herb has unique characteristics that make it easily identifiable:
The spiked water-milfoil has a long stem that can reach up to 10 feet in length. The stem is covered with feathery, dark green leaves that are arranged in whorls. The leaves are finely divided into many thread-like segments, giving them a delicate and feathery appearance.
The plant also produces unique spiked clusters of flowers that emerge above the water’s surface. These floral spikes are dense and slender, resembling a spike or a finger.
Spiked water-milfoil is a fast-growing species that can quickly colonize large areas. It spreads through vegetative reproduction, with new plants growing from fragments of the parent plant. This rapid growth can lead to the formation of dense mats of vegetation, potentially affecting water flow and aquatic ecosystems.
Additionally, spiked water-milfoil has the ability to overwinter under the ice, allowing it to survive and continue its growth in the following seasons.
This aquatic plant is native to Europe, Asia, and Africa, but it has been introduced to other parts of the world, including North America. It thrives in a wide range of aquatic environments, from clear waters to those with high nutrient concentrations.
Spiked water-milfoil is often found in shallow water, but it can grow at depths of up to 20 feet. It prefers slow-moving or stagnant water bodies, where it can take root and spread efficiently.
Overall, the characteristics of spiked water-milfoil make it an interesting and important species to study and understand, as it can have both positive and negative impacts on aquatic ecosystems.
