ELEOCHARIS OBTUSA - COMMON SPIKERUSH

 
Common Spikerush - Eleocharis Obtusa
The Common Spikerush is a very versatile plant, but does best in wet soil. Though generally short, they can grow up to 4 feet tall. Their stalks are tall with triangular cross sections that spiral in three layers. At the tops of these stalks are small golden brown flowers with a spike-like appearance. Common Spikerush is important to wetlands. It will grow best in zones 4 through 9 and prefers moist to wet soil conditions. It will only grow to be just over a foot tall. It will not do well in dry soil it needs to be went to thrive. It will survive to be up to 20 years old, and it will enjoy full sunlight. The most active growth time is from April to May. It is an excellent plant for lakes, ponds, and other wetlands. Since it is tolerant of hardy winters, it is very common, but does die out if the temperature gets below 30 degrees. As the common name would imply it is found in every state except Georgia and Florida, where other spike rush species take up its place. It is seen growing in mountain bogs, streamsides, along rivers, in the desert alkali wetlands, and even coastal swamps. It will remain green throughout the year in most states. It would also be great for use to fill in large bare spots in lawns or fields. It has a hardened nutlike fruit called an achene with a single seed. The achene's head is adorned by a diamond shape tubercle or short tooth. It's achenes are bright golden yellow and smooth, with the tubercle that is arrowhead shaped on top. A wide variety of wetland bird species obtains meals from the fruits of this plant. It's flowers are enclosed by a dark brown or black bract and is not very showy.
