Crassula Helmsii

Description

Crassula Helmsii, commonly known as swamp stonecrop or New Zealand pigmyweed, is a water-loving succulent that belongs to the family Crassulaceae. It is native to Australia, New Zealand, and Tasmania, but has become an invasive species in many parts of Europe and North America. Its ability to grow rapidly and form dense mats on the water surface has led to its classification as a noxious weed in many countries.

Taxonomic Information

Appearance

Crassula Helmsii has small, oval-shaped leaves that grow in opposite pairs along the stem. The leaves are about 3-6mm long and 1-3mm wide, and are a glossy, bright green color.

Care Guide

Crassula Helmsii is a relatively easy plant to care for, but it requires specific conditions to thrive. Here are some tips on how to care for this water-loving succulent:

• Water: Crassula Helmsii requires a constant supply of water to survive. It should be grown in water that is at least 10cm deep, but not more than 30cm deep. The water should be changed regularly to prevent the build-up of algae and other harmful substances.
• Fertilization: The plant does not require regular fertilization, but it can benefit from a small amount of liquid fertilizer added directly to the water once a month.
• Soil: Since Crassula Helmsii is a water-loving plant, it does not require soil to grow. It can be grown in a variety of containers, such as plastic pots, glass jars, or even fish tanks.
• Sunlight: The plant prefers bright, indirect sunlight. It should be kept away from direct sunlight, which can cause the leaves to burn.
• Hardiness Zones: Crassula Helmsii is hardy to USDA zones 9-11, which means it can be grown outdoors in areas with mild winters and warm summers.
