This has sprung up in the middle of my garden and is about 3-4 inches tall. The stem seems woody. It does not look familiar to me.
Any ideas?

I don't know what all those little white specks are – I didn't notice it at the time – perhaps it attracts every aphid within miles.

grow a tree from a stone, are near fruit trees ?
looks like an Apple tree in a sunny position
nucleolus of apples can fall or compost

Perhaps hawthorn?

At first glance I thought apple or pear, but when I look better I don't think it is.

I'm not at all familiar with the plants you might have up there.

I'd certainly say it's a tree or shrub.

The white specks just look like sand from here, all I see is irregular dots, no legs or heads, some bug eggs look similar but they'd be organized and all the same shape, or perhaps on a stalk, which I don't see.

No fruit trees anywhere around, although there is an ornamental tree uphill from me.

I will go look at the leaves.


Nope. Not that one.

but can, It is an ornamental Apple tree bred, from the pips but grows the original species, can't keep bred properties.

So either it comes from my compost or some little bird hopped around my garden.
Perhaps I will watch it for a while before I decide what to do with it.
Thanks for your help.

It will be a wild apple tree, the fruit of disgusting taste, You can graft.
