Filamentosa is basically trunkless. If you want the look of a trunked yucca in your yard you could try Yucca recurvifolia or possibly Yucca rostrata. In your climate they would probably require some protection such as a south facing wall. A raised, gravely bed would also increase your chances of survival. Go to the Plant Delights Nursery web site and look at their yucca offerings.

Don ..... I grow half and dozen or so Yucca trees here on the east coast and I actually like the look they give more them palms. The grand-daddy of them all in size is the Yucca faxoniana ... huge barking trunk in diameter and very cold and moisture tolerant ..... the Rostratas are nice too, the Yucca elata in my opinion is the most cold and moisture tolerant maybe only second to the Rostrata. Make sure you plant them in well drained soil, do not over water, and you may want to raise the bed a good 6-12 inches .... make sure you identify where the root and trunk lines are and do not plant the yucca above the trunk line, it will rot at the base if you do so ... do not heavy mulch either ... Yuccas are very cold tolerant, more so then palms but they can not stand long period of moisture in the winter months, mulch holds to much moisture around the base, they are better off taking the cold at the cost of keeping as much moisture away from the base. Calplants mail-order in Vegas has large size Yucca trees for sale and ship. Good luck Like another post here ..... Windmill palms, do you protect them in the winter???

Most likely multiple plants. Recently I have seen stores are getting various kinds Ficus and most are multiple rooted cuttings in a single pot. I guess they look fuller that way and perhaps more attractive to customers. For a multiple trunk tree the individual trunks will be very close to each other at the soil line.

what is your plan with this thing.. will it be going on mother earth.. or remain potted forever??? as you can see here.. they are not small plants for pots: https://duckduckgo.com/?t=ffcm&q=Podocarpus+Gracilior&iax=images&ia=images the potential lifespan for this conifer.. is counted in decades ... i suspect you have some instant gratification issues with wanting to prune it.. to shape it ... whats the hurry ... lets figure out why it lost its leaves previously ... how you can do better ... and lets leave the pruning shears in the house for a year or two ... and best of all ... lets figure out how to plant it in mother earth.. or how to properly get you set up with it living in a pot long term ... more facts please ken
