Sterile: Free from living microorganisms; in botany, incapable of producing viable seeds or pollen.
Think of “sterile” in gardening like a doctor’s surgical tools: completely clean and free of any unwanted living things. This is important when starting seeds or propagating plants, as it prevents diseases from spreading. In terms of plants themselves, a sterile plant is like a flower that can’t have babies; it might produce beautiful blooms, but no seeds will come from them.
In a home garden, you might encounter the concept of sterility when sterilizing soil or seed-starting mixes. This is often done by heating the soil to kill off any harmful bacteria, fungi, or weed seeds. It’s like giving your seedlings a clean and safe environment to grow in. As for sterile plants, they are often bred for their showy flowers because the plant puts all its energy into blooming, not seed production. This can be desirable in some situations but also means you can’t propagate the plant from its own seeds.
Ultimately, sterility is a tool and a characteristic. It’s about creating a clean environment for your plants or choosing plants prioritizing beauty over reproduction. It’s like having a clean slate, or a plant that’s all dressed up with nowhere to go, reproductively speaking.
