Nice looking fruit!

Interesting. If I get back to the Citrus Collection this year, I'll ask about it. Still waiting for the grafting class to be a go.

It is difficult sometimes to determine from a picture just how large, or small, an object is, when there is not a known object to relate its actual size. From the picture shown, it seems to be quite small for a pummelo. The way the industry is going, specially with the Italians, in 20 years there might be a red colored fruit of every known type of citrus, due the current rage of crossing with blood oranges. - Millet

I'm not complaining, the red fruits are pretty cool.

So it's not just the Italians who create this kind of hybrids!
The description says it is grapefruit sized...
