Sea Purslane Info:
It’s thick vigorous roots form dense underground net-like mats often in areas normally in scorching full sun under salty sand all day! It can survive up to a week fully submerged under salt water before the leafy portions begin heavy disintegration. Meanwhile they can grow with roots fully submerged in salt or fresh waters (say floating beds aquaculture style), as well as grow in ordinary earth as a durable edible (whole plant) groundcover. It’s versatility has it suitable for salt marsh environments, as well being capable of growing in clay soil types. Most fascinating… it performs phytodesalination, that is it strips salt from it substrates (soil, water etc)!
Sea Purslane As Natural Marine Aquarium Filtration:
Properly arranged, it should prove a quality reef tank / saltwater marine aquarium specimen for refugium sump (possibly tide pool style) filtration for nutrient export (where the stems & leaves hang out above the water and can easily be trimmed off as it grows). The trimmings can go right onto your dinner plate as garnish, so if your aquarium methods don’t render those cuttings fit to eat (at least after a couple months) then you aren’t doing it right! But for the sake of argument this is a prime species for environmental phytoremediation meaning it soaks up toxins (which should break them down but in wild over-polluted environmental situations they’ll probably be overloaded and only be eaten in moderation to the situation).
Sesuvium portulacastrum is effectively natural substitute for Purigen, a fine synthetic polymer product that removes heavy metal toxins. Sea Purslane is well documented for removing heavy toxic elemental metals like Arsenic (As), Cadmium (Cd), Chromium (Cr), Copper (Cu), Lead (Pb), Mercury (Hg), Nickel (Ni) and Zinc (Zn), along with other toxins such as the sulphonated azo dye “Green HE4B”, as well as other various organic human pollutants within sulphates, chlorides and more.[1 2 3 4] Apparently this plant is so effective with metals it also may strip out Iron (Fe) and Manganese (Mn) which may be of consideration for a saltwater aquarist. Considering the above, in terms of edibility of export cuttings, for first month or so with it attached to your system might not be eaten, if never ‘properly’ filtered out before. From there, it should stand to reason Sea Purslane will inherently absorb Nitrate, Nitrite and Phosphates, typical of most any plant, while its clear it definitely removes ammonia nitrogen & nitrite nitrogen rather dramatically .
One might argue this to be the ultimate marine aquarium filtration plant considering its foliage rests outside of the water zone (and all of the above). Since roots are normally associated with absorbing mostly/only oxygen, potential CO2 related headaches should be marginal. Mangroves are a popular plants grown roughly the same style in light here, yet many scoff them due to slow growth and far less than ideal trim-ability. With Sea Purslane we get the same inside+outside of the water growth arrangement as Red mangroves, yet this stuff grows like weeds! Just leave nodes for new shoots behind your cuts (rule #1 when it comes to pruning most plant types) and make some dinner (with the plant not the fish of course) when it goes wild.

Plant Germplasm (definition): Any portion of genetic material that can be grown into a live plant. Examples include seeds, stem cuttings (via many methods including air layering), root cuttings, root divisions (multiplication via division), leaf cuttings, leaf fragments (in tissue culture), rooted nodes (vines), “eyes” (offshoots from potato tubers), cacti pieces, etc. The term germplasm can also be used to describe a collection of genetic resources for an organism such as as a seed collection or, for trees, a nursery.
