In environments with less light, plants grow more slowly and use less water.Low lighting is not sufficient for starting seeds indoors.In their native growing environments, these plants are “understory plants” meaning they grow underneath the branches of larger plants. Low-light plants require little to no direct light.A low-light plant would be suitable for a north window or a fairly dark corner.While a plant may tolerate lower light growing conditions, more light may be required to promote dense foliage and flowering. Then choose plants with light requirements that match your indoor environment. Even though this window is south-facing with plenty of natural light, the plants get indirect light for much of the day.īefore getting a plant or starting seeds, determine the quality and hours of natural light in your space. Humans have known about this moss for centuries, even if they didn’t understand the mechanisms that cause it, and that is why this wonderfully unique species has earned so many common names.Overhanging roofs can block light for part of the day. When observing goblin’s gold protonema that develop under high light conditions, researchers have found that they do not develop lens shaped cells and therefore are not capable of reflecting light in the same way. ![]() Interestingly, there appears to be some plasticity to this light-concentrating habit as well. Also, the protonema itself is capable of asexual reproduction so colonies can grow to epic proportions in dark areas, only producing mature gametophytes in a few spots. When that refracted light mixes with the green light that isn’t absorbed by the chloroplasts, it bounces back into the environment, giving the whole protonemal mat a green florescent glow when viewed in just the right way.īy being able to make use of what little light finds its way into these dark habitats, goblin’s gold can grow largely free of competition. As light enters the lens, small amounts of it are refracted around the cell. The light concentrating mechanism of the goblin’s gold protonema happens to have a wonderful and stunning side effect. Through this process, each cell is able to concentrate what little light is available so that they can photosynthesize in light so low that nearly all other plants will starve. Being able to sense the direction of the light, the chloroplasts within each cell can actually move around so that they are always in a position that maximizes their exposure. When light, no matter how weak, strikes these lens cells, the curvature focuses the light down into the cell so that it is concentrated into the tip at the bottom. The opposite side of each cell narrows to a cone. When grown in deep shade, the protonema of goblin’s gold develops a layer of lens-shaped cells on its surface. Luckily, the protonema can make do with much less light that the mature gametophyte, which also happens to be how this tiny moss earned so many interesting nicknames. In much the same why that fungal hyphae fan out into the soil in search of food to decompose, goblin’s gold protonema fan out over the damp substrate, searching for spots where enough light filters through to fuel growth. To grow long enough to reproduce, it has to find spots where there is enough light to complete its lifecycle. Because goblin’s gold grows in such dark habitats, it can’t afford to grow its gametophyte anywhere. The protonema spreads outward as it grows, gradually producing hormones and other growth regulators that will control the development of the mature gametophyte. ![]() ![]() Instead, it grows into thread-like, multicellular fillaments called a “protonema.” You can think of this as the juvenile stage of the gametophyte. When a moss spore germinates, it doesn’t immediately look like what we would recognize as a moss.
