Here's the "how to " from a cutting:
and by seed:
Clean the seeds of their fleshy pulp in the early summer and sow outdoors. Germination is sporadic from one to two years. Alternatively, collect umbrella seeds in the fall and refrigerate them for four to five months at 40 degrees Fahrenheit. This is called cold stratification and mimics winter cold that prepares seeds for germination in the wild. Plant seeds in the summer in a bed of mulch at 70 to 85 F. The seeds should germinate in three to four months.

Hi Sharon, hope this helps,
Just what you need, a video tutorial for you: https://www.youtube.com/watch?v=alCB0XJr9hk
Hello here’s a link that should be informative. Hope this helps. Happy gardening!
Maybe plant little umbrellas such as these:
Thank you Betsy. It's nice to know that the picture brought a smile for at least one other person.
Hi Sharon. Propagating cuttings will create a perfect clone of the parent plant, with no chance of mutations as you would encounter with planting seeds. Take a cutting from your plant.
Plant it about 2 inches deep in a pot filled with soil. Gently pat the soil around the stem to secure it in place. Water the soil and place the pot where it will get steady light but not direct sunlight. Check on it every day and keep the soil moist. I hope this helps you Sharon. I hope you are well.
Fill a large flowerpot with well-drained potting medium such as sand and vermiculite, or perlite mixed with peat or sphagnum moss. If using your own potting medium, sterilize it in your oven at 180 degrees Fahrenheit for half an hour. Most nurseries sell pre-sterilized potting mixes.
Water the potting medium until water escapes from the hole in the bottom of the flowerpot.
Take a terminal cutting -- one with a functional growing tip -- from one or more branches. Cut through a stem about 3 inches behind a group of leaves.
Plant the stem 1 or 2 inches deep in the potting medium. Set the plant in a bright, humid spot. To accelerate rooting, place the pot over a heating mat.
Place a clear plastic bag or glass jar upside-down over the plant to enclose it and create a humid greenhouse-like environment. If using a plastic bag, secure it with a rubber band.
Mist the plant with water under the bag or jar once daily to keep the plant moist but not excessively damp.
Remove the bag or jar once the umbrella plant takes root in about 6 weeks.
Bend the head of the umbrella plant down into the water and into the mud.
You will have to scroll way down this site to get to the information on propagation, but you will learn a lot along the way!
