Myriophyllum elatinoides 'Snowflake'
Common names: Myriophyllum Elatinoides 'Snowflake', Myriophyllum elatinoides
A medium to tall aquarium or wetland plant with fine feather-like leaves arranged in snowflake-like whorls and light to medium green with possible pale tips. Best used for fine pale-green stem groups; care and final appearance vary with aquarium conditions.
This medium to tall plant has fine feather-like leaves arranged in snowflake-like whorls. Its commonly observed colour is light to medium green with possible pale tips. Colour, leaf size, and internode length can change with light, CO₂, nutrients, temperature, and the individual plant.
It grows from soft upright stems with foliage that can be damaged by rough handling or debris.
It is normally used for fine pale-green stem groups. During the first few weeks, watch the growing tip, roots, and new submerged leaves. Do not judge success only from old nursery-grown foliage.
Injected CO₂ is recommended for the best form, although it is not automatically required. Stable CO₂ often produces faster growth, shorter internodes, larger or healthier leaves, and denser groups.
CO₂ must remain stable and be balanced with light, macro- and micronutrients, circulation, and oxygen. Adding CO₂ does not make very strong light automatically safe.
Increase light or fertiliser only after the plant is producing healthy new growth. Sudden changes can cause melting, algae, or stalled tops.
This plant should be rooted in substrate, floated, or allowed to spread through runners according to its growth habit. Do not glue healthy stems, crowns, or roots to wood or stone.
Frequent light trimming usually creates denser growth. Long delays between trims can produce shaded, bare lower stems.
Propagate only healthy growth. A melting, algae-covered, or recently imported plant should recover before being divided or cut heavily.
Transport, planting, and conversion from emersed to submerged growth can cause temporary leaf loss or slow growth.
Snowflake is a cultivated trade form. Fine leaves trap debris easily and need gentle circulation and regular topping.
Yellowing, holes, pale tips, red colour loss, twisted growth, or slow growth can have several causes. Possible causes include nutrient imbalance, unstable CO₂, unsuitable light, temperature stress, damaged roots, adaptation, algae, or physical damage.
Old damaged leaves will not repair themselves. Use the next several leaves to assess whether the change helped.
