Rumex maritimus aka Maritime Dock
Taxonomy ID: 9329
Rumex maritimus, also known as golden dock, bristle dock or seashore dock, is an annual plant species from the Polygonaceae family. It can be found in Argentina, Burma, Canada, China and the United States, but is native to Canada and most of the 48 states. The plant typically grows to be 15 cm to 75 cm in height, with upward or ground-laying stems and wedged-shaped leaves that are commonly narrow on both ends. The inflorescences on the leaves and stem of Rumex maritimus are golden yellow or green/yellow in color. The species is hermaphroditic and pollinated by wind, with flowers that produce triangular or rhombic triangular flowers ranging from 2.5 mm wide and .75 mm tall to 3mm wide and 1.2 mm tall. Rumex maritimus prefers moist or wet soil, but can tolerate maritime exposure. While it can grow in semi-shade or no shade, it does best in direct light less than 1 foot from a window. As a super rare houseplant, Rumex maritimus needs regular watering and well-draining soil, and typically doesn't require added fertilizers if repotted each time it doubles in size. It should also be noted that this plant may be poisonous.

How difficult is it to take care of Maritime Dock
Even if you don't have a green thumb, you can successfully care for Maritime Dock due to its easy-going nature.
What is the growth pattern and size of Maritime Dock?
Maritime Dock grows vertically and new growth emerges from the top of the plant.
What is the region of origin of Maritime Dock
Maritime Dock’s native range is Europe, including Britain, from Scandanavia south and east to Spain and the Caucasus.
What are the water needs for Maritime Dock
Maritime Dock should be watered regularly, allowing the soil to dry out between waterings.
What is the right soil for Maritime Dock
Maritime Dock loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
What is the sunlight requirement for Maritime Dock
Maritime Dock thrives in bright and direct sunlight. To ensure your plant receives enough light to survive, place it less than one foot from a window. The current weather in your area may affect the placement in your home. For example, if you live in a region that has longer and more intense periods of sunlight, then you may want to place the plant farther away from the window to avoid direct sunlight and reduce the risk of sunburn. Alternatively, if you live in a region with relatively milder temperatures and less intense sunlight, then you may be able to place the plant closer to the window for increased exposure. Ultimately, the current weather in your area should be taken into consideration when determining the best placement for your Bristle Dock.
How to fertilize Maritime Dock
Repotting the Maritime Dock is necessary either when it has doubled in size or once every year, whichever happens first. With fresh potting soil replenished annually, the plant will receive all the necessary nutrients, rendering the use of fertilizer unnecessary. Keep in mind that the source of a plant's energy is the sun, not fertilizer.
