I heard a little more about this mysterious shrub near Bristol. It is
growing over a 3' high wall, the leaf isn't toothed or in any way other than
an 'ordinary' leaf-shaped leaf (bit like a lemon tree leaf, she said) and
it has tiny thorns about 1cm. long. As they're maturing, the little fruits
are becoming more orange. It definitely isn't the 'stick pumpkin' suggested
a few days ago. Quite rightly, my friend is unhappy about taking photos of
someone else's property without their permission and although she rang the
bell, there was nobody home. If another attempt fails, she'll slip a note
through the door, asking them to ring her if they know the plant's name.
Unfortunately, she thinks it very likely they won't as this is an area of
very old houses where there has been a lot of coming and going over the
years.
If that's the case we'll have to wait until and if, our pips grow into fruit
bearing shrubs.
