Strange plant

I think it is Lantana.

Yes, I agree with you, Elleme, definitely Lantana.

It's frost tender, so most people treat them as annuals in the UK.

I also think it's Lantana. Be careful of the berries though, they can be toxic to animals (including dogs) and children, a fact which the garden centres in the UK don't make very clear on their labels. My friend's granddaughter ended up in hospital after eating a berry.

Okay. I appreciate everyone's input. I do have lantana growing on my property. The leaves are 1/2 to 3/4 of an inch long. This plant is growing erect. The flower clusters are the size of a silver dollar (maybe slightly larger) and the leaves are 3" long and 2" wide. The texture of the leaves is also very different from my lantana. Do different species of lantana have these kinds of differences? I really don't know but maybe one of you are more knowledgeable than I am. I just plant and watch things grow but my knowledge is quite limited.

I am so impressed with you guys. I began to research lantana on the internet and sure enough this plant is a lantana camara. I have lived at this location (Clifton, AZ) for three years and I am living in the old high school band room building. I have had some really strange plants beginning to show themselves since we have had more rain than ususal. I think this lantana plant will be a keeper along with the wild rose bushes which have also let their presence be known. Thanks to everyone for their assistance.

Thats Lantana:)It looks like Lucky sunrise Rose:)I could be wrong but that's what it looks like to me
