Which plant's seeds have a notable dispersal method involving sharp pointed capsules?

Bittercress is known for its unique seed dispersal mechanism. The seeds are housed within sharp, pointed capsules that, when mature, develop tension and can burst open explosively. This explosive dehiscence allows the seeds to be forcefully ejected from the plant, enabling them to travel a significant distance away from the parent plant. This effective dispersal method increases the chances of successful germination and establishment in a new location, as the seeds are scattered widely.

In contrast, the other plants listed do not have this distinctive method of seed dispersal; they are less specialized in how they release their seeds. Understanding the dispersal mechanisms of different plants is crucial in managing them, especially in terms of weed control in ornamental and turf situations.
