@Embothrium Thank you for naming the plant. I was just wondering, do you think it will grow into a bush or tree?

My first thought was some sort of Banksia, but maybe my eyes are just Oz-centric.

I reckon Embo has nailed it...

" I was just wondering, do you think it will grow into a bush or tree?"

What form is it taking now and do you intend to ever prune it?

HU, I'll wager that there are Toyon shrubs all over the place in your community, you've just not noticed. They are covered with red berries in the fall, does that ring a bell?

Botanically speaking, Toyon (common name) is described as a large shrub. However, large shrubs are very successfully pruned into small tree forms all the time; it's a practice that I strongly encourage for the right plant and right place. It can also be botched by an untrained practitioner.

Am curious about the environment in which this particular plant is growing.

May I suggest that if you decide to frequent the Gardenweb, you take the time to sign in with a recognizable user name. The HU number is off putting at the worst, makes you unrecognizable to this community at best.

when you are given a latin name.. take it to a search engine.. and flip to the images side.. and you can 'see' hundreds of pix ... which will give you a general idea.. of what its natural form is.. and what it might be pruned into .... i see some that have been pruned.. to a tree LIKE form ... though those plants look decades old ...

@cearbhaill I found it growing next to my orange tree last week and I replanted. This picture is was taken last week so this the current form. I don't mind it growing into a large bush but I do prefer a tree. To answer your question, yes I think I will be pruning it if it will train the plant to grown into a tree.

@rhizo_1 I have a few thorny pyracantha plants in my yard which grow red berries and have started to become invasive but I don't think I have come across a toyon plant before. Or maybe I just wasn't looking at the plants right.

Next step will be to see if it comes through being dug up in August. Especially if it is a self sown seedling that has never been disturbed in the past.

The red berries are more winter in timing, hence one of the common names, Christmas berry. California has laws against harvesting the berries in the wild, due to their popularity during that season for decorating wreaths and other holiday items.

see section one of the link below ... timing is important ... as noted.. august is rarely the right time.. for a vast majority of us ... just too much stress on the leaves. to cut off half the roots ....

note the section on proper watering .... and perfect that ...

dont be surprised if it starts losing leaves... due to the stresses ...but if you water and keep the roots alive .... then it can releaf .. sooner or later ...
