Scientific Name
Crassula helmsii (Kirk) Cockayne
Common Names
Swamp Stonecrop, Australian Swamp Stonecrop, New Zealand Pigmyweed
Synonyms
Bulliarda recurva, Tillaea helmsii, Crassula recurva
Scientific Classification
Family: Crassulaceae
Subfamily: Crassuloideae
Genus: Crassula
Description
Crassula helmsii is a small aquatic or semiterrestrial species of succulent plant. The shoots are rather stiff, carrying narrow parallel-sided leaves in opposite pairs, each leaf being up to 1 inch (2.5 cm) long. Small white flowers with four petals are produced in summer on long stalks arising from the upper leaf axils.
How to Grow and Care
Crassula are easy to grow, but they are susceptible to mealy bugs and fungal diseases. As with all succulents, overwatering is sure to be fatal, so err on the side of too dry rather than too wet. Never let your Crassula sit in water. If you water from beneath by letting the plant sit in a saucer of water, make sure to pour off any excess water after a few minutes.
Repot as needed, preferably during the warm season. To repot a succulent, make sure the soil is dry before repotting, then gently remove the pot. Knock away the old soil from the roots, making sure to remove any rotted or dead roots in the process. Treat any cuts with a fungicide. Place the plant in its new pot and backfill with potting soil, spreading the roots out as you repot.
