There are two cultivars of dwarf pomegranate, 'Chico' and 'Nana'.

'Nana' is REALLY tiny and has REALLY small ornamental (not edible) fruit.

'Chico' is the bigger one -- it will get to maybe 4 feet -- and has larger (but still inedible) fruit.

Both do fine in the Bay Area.

I have Nana here and it is 15 years old and between 5 and 6 feet tall with no pruning. I don't expect much if any more height. It blooms beautifully every year but has not made any fruit. Most years it does not completely lose its leaves over the winter, but last year it did. I bought it in a four inch pot from Carmen's Nursery and it took a couple of years to reach one gallon size when I planted in the ground. Al

I've got Nana pomegranate, it never went beyond 2 ft tall. The fruits are edible, they're tart, but they're edible enough. Quite juicy even for tiny size from 1/2" to 1 1/2" but all contained edible arils. I will germinate more seeds from the fruits I harvested.

I plan to graft them with other cultivars soon. I will be using them as ultradwarfing rootstocks. I will be looking for Kazake, Ink, Parfianka and other potentially good types of scionwood.

One thing nice with pomegranate is that they can be grafted as easily as apples and pears.

I know you want a "dwarf" but since the dwarfs here produce inedible fruit, I would share my experience:

I have a "wonderful" variety in SF bay area. It is in the ground and does produce lots of fruit. It is about 6-7 feet high, perhaps same in circumference.

I remember reading somewhere that you need to thin out some flowers so the tree can bear good size fruits. I do not do that (for lack of time) and my fruit is of medium size/little tart. My neighbor has one as well, and I have seen huge fruits on their tree, so I know it works.

Overall worth trying. If you can plant it close to a driveway or a mass of concrete, even better. It loves heat.

I have a dwarf which I think is 'Nana.' It is probably 6 feet high. It does bear fruit but they don't ever turn really red--more like yellow with red cheeks, like Gala apples. They are pretty to look at on the tree, and edible, but the seeds are pale pink and quite tart.

I love pomegranate juice but find it hard to imagine squeezing my own, and eating them is kind of a novelty treat, so I'm happy with my little tree.

It gets lots of sun in a spot along the driveway. I have it planted in front of a row of irises: When it loses its leaves, the result is a lovely silhouette of branches, a yellow carpet of leaves beneath, and a wall of vertical green iris leaves in back--an unexpectedly poetic combination. I didn't plan it, but it is one of my favorite fall "moments" in the garden.
