Somewhat new to the United States aquarium interest, Pogostemon helferi has an unmistakable and special overall look. With wavy leaf margins and compact bushy expansion, it stands out not only in its genus but amongst all aquarium crops.
Typically acknowledged by its frequent identify downoi (“little star”), P. helferi is observed at the edges of streams in Asia. Throughout the damp period, it grows submerged and generates dense mats. In the dry period the crops are uncovered, and in the emergent sort the internodes will lengthen. Interesting but compact (significantly less than an inch) purple bouquets will sort on a terminal spike.
P. helferi is not significantly hard to improve if its requirements are satisfied. Delicate to medium-challenging h2o with a wholesome substrate can be useful, but accessible h2o column nutrition are essential to access the comprehensive likely of this species. Enough nitrogen will consequence in broader, darker eco-friendly leaves, and together with greater lights, really encourage compact expansion.
Other macronutrients these as phosphorous and potassium are essential but not essential in good quantities. Micronutrients ought to be considerable for the finest outcomes. If lights is way too dim, the internodes could lengthen and leaf form will be significantly less captivating. Extra COtwo injected into the h2o will assist in healthful expansion and is proposed.
Propagation: The abnormal overall look of P. helferi could feel to existing a problem, but it can make an interesting mid- to foreground plant in the correct format. Irregularly formed plantings of it in the midground with small-rising carpet crops like Hemianthus callitrichoides in the foreground operates properly. Meticulously positioned rocks will enhance the format with no drawing way too significantly consideration from the crops. Development fee is not significantly speedy, so it is attainable to sustain a steady overall look with no regular trimming. P. helferi is not likely to access the area in all but the most shallow aquariums.
Notes: Sideshoots will produce as the crops experienced, producing a bushy overall look. Roots will quickly sort on the sideshoots, and you can snip them off and replant to commence a new cluster. It is also attainable to snip off the tops of the more mature and taller stems, leaving the foundation and sideshoots intact, and replant the clippings in entrance of the cluster.
As they improve out, you will accomplish an interesting, staggered overall look and the illusion of much more crops in a smaller sized area. P. helferi is bought by a number of business nurseries in the U.S. and can typically be attained simply from fellow hobbyists.
