We have two plants we were given and neither we nor the donor know the
variety. The first is a climbing nasturtium which in a pot, in an
unheated polytunnel, has gone to 8' and is spreading along the wires.
It still has flower buds on it. The seeds came from a friend whose
nephew brought them back from Chile - so perhaps you begin to see the
difficulty in getting an ID! The flowers are orange with a 3 to 4"
long stem and a spur that is 1.5 to 2" long. The inside of the flower
has darker orangey/red, very fine stripes right in the throat of the
two larger top petals and each of the three smaller low petals has a
red blotch on it and is fringed. I should think each flower is
probably about 1" diameter. It's a really charming plant and both
vigorous and floriferous and we'd love to know what it is.

There was an article in a recent issue of The Garden about the national
collection of Tropaeolum - if no one beats me to it I'll see if that
sheds any light on the ID.
