Well, we'll get the confusion out of the way first - Ray and I were thinking
of two different rosemaries in two different gardens, as things turn out! I
was convinced both were in one garden but clearly I'm wrong as we found
today. And the owners of both houses are abroad so the plot got a lot
thicker. However, we went over to Salcombe today to the house he was
thinking of and took a photo of the rosemary there. Olivier Filippi says he
seriously doubts it's R. Barcelona because that one gets damaged by frost
even in his trial garden and he says it's not worth photographing.
However, I've sent him a photograph of the Salcombe one and promised him
some cuttings if it isn't one he has. He has never heard of Jackman's
Prostrate, either and Burncoose have no photo of it. Filippi has asked for
cuttings of that, if I can get some and has promised us some cuttings of new
cultivars of his, in return, which is very kind.

Burncoose have also had a photo from me and I'm waiting to hear back from
them. They say the one in their car park is Jackman's Prostrate but they
have no idea of its provenance and say only that is has been around a long
time, so it's certainly possible that it's got more than one name and that
the nursery in the east of UK got it from Burncoose under that name. I hope
our photos of the Salcombe one will be on our web site soon but if anyone
wants an email pic, let me know.

Ray thinks it's possible/probable that the other rosemary I was thinking
about is the same one (the two couples are friends and neighbours) but
because it's on a much lower wall in the second garden, it runs across the
path and on down another wall, IIRC.
The one we photographed this afternoon is on a wall that is probably about
10' high in places and it hangs right down to the ground where it has been
trimmed just to touch the tarmac drive. The wall is rendered, so it isn't
rooting and sending out new plants from any cracks or joints in the wall; it
hangs in a solid curtain.
