As the Dirtswimmer Radiogrub breaks up more of the soil, increasingly more nutrients are released, leading to more productive soil communities. With the soil on HRI becoming more fertile, this would obviously be followed with an increase in floral diversity - one such new flora is the Radiograss.

The Radiograss thrives in the land’s more productive soils, with wide, deep roots to absorb as much water and nutrients as it could. Its fronds are long and blade-like, shooting upwards from the soil to maximize photosynthetic potential. A network of vascular tissues help distribute essentials throughout the flora. To deal with grazings from Horrible Irradiated Baloons, the Radiograss incorporates small quantities of lead compound in its fronds, making it a much rougher meal; this has the consequence of giving its older fronds a slight weight. As this becomes the flora’s primary defense, the ancestral adhesive has been repurposed into a coagulant. One would expect to find the greatest densities of Radiograss in the steppe-like south of HRI, where winters are not as brutal as the tundra to the north (if only because of the intense radiation there). With its radioactive emissions keeping its patch of soil and the surrounding air warm, the Radiograss simply goes dormant with the onset of the polar winter darkness. Often this flora shares its range with the Horrible Piss Bush in stable coexistence thanks to the greater access to soil nutrients and its own greater lead content.

Besides photosynthesis and fusiotrophy, the Radiograss also incorporates trace quantities of spite in its tissues. The spite has the benefit of protecting younger flora from attack before building up their lead reserves.

Given enough space and if conditions are plentiful enough, new Radiograss are bud from the parent’s runners. Aside from this, spores are sent into the wind, which will hopefully settle in a suitable growing spot and develop into new flora.
