California grey rush 'Elk Blue'

Juncus patens 'Elk Blue' | Also known as: California gray rush 'Elk Blue', Blue rush 'Elk Blue', Spreading rush 'Elk Blue' | Rating: 0 votes | Print / Pdf

One of the most common species of rush, juncus patens is also one of the most preferable due to its attractive dome-shaped habit. Its tall, lean stems are usually grey or blue-green in colour, thus the reason it is known by some as the blue rush, but its vigorous spreading trend means it is best known as the spreading rush. It thrives in marshy areas with its light brown six-tepalled flowers emerging in spring from the side of the stems rather than in spikes at the top. Spreading rush grows best in acidic, marshy soil, so it is perfect for ponds, lakes and stream banks. But it can also be planted in containers and maintained in city gardens.
