Esfera grow to a diameter of about one metre. Their roots are shorter than those of the Lige or Haarukka, as the Esfera does not need to be anchored so strongly. This is due to its spherical shape. The spikes on an Esfera are needle-thin and sharp, but make up for it by containing a deadly poison. Once it infects a victim's bloodstream, they will die slowly and painfully, over a period of 24 hours.
Esfera get their nutrients through the soil alone. The main roots, that anchor the plants, are short, but longer, slimmer tendrils reach down much deeper, to reach fertile soil that hasn’t been baked by the sun.
