Non-flowering plants reproduce by a ground-layering process such as sending air roots, side shoots or runners. See how various non-flowering plants reproduce without seeds with plant advice from an urban horticulturist in this free video on gardening.
Hi, I'm Stan DeFreitas, Mr. Green Thumb. How do plants reproduce that don't have flowers? Well, a lot of our flowering plants, they're going to produce seeds, and that's an easy way for them to reproduce, but there's a whole bunch of other plants out there, that don't have flowers, and they can reproduce by either kind of ground layering, where a branch will kind of reach over, and go into the ground, or it may send air roots down, like some of the ficus members do. Some of the ficus members can travel up to a quarter of a mile, with their rooting system. They send out a branch, the roots fall down, roots come down to the ground, they peg in, and then they start to root. Bamboo plants will send up side shoots. Many of the grasses will send runners, either stolons or rhizomes, and as those little side roots and shoots come along, they'll come back up, and start a new plant. We see that in St. Augustine grass. We see it in a number of grasses actually, but you'll also see it in a number of other plants as well, where they'll come along the roots area, and they'll tend to send up another shoot, when it's far enough away from the mother plant. Starting plants, by doing that of course, you can help by doing your own cuttings, or sometimes by taking a layer, putting it into a ground, into a pot, putting a brick on top, and letting it root that way as well.
