Strawberry plants

They to send out runners that produce young plants. They start with no roots and as the runner grows more appear and the oldest runner plants begin to put down roots. I
f you want more, then dig a hole below a runner plant, place a plant pot with soil in under the runner plant and peg it down into the pot. Keep watered and within a few weeks,the runner plant would of put down roots into the pot and if all the plantlets along the runner have been rooted like this, then you can separate them from the parent plant and there you have it. Don't remove from the parent plant before it roots or it will die.

If, like us, the birds eat a number of the fruits, you may get self seeded plants in various places. Not all of them produce good fruit, but enough to to be worth keeping to fruting size.

you are right they do produce new plants on runners like spider plants.
