Tropaeolum ciliatum

Hi Roger,

I grow a number of Tropaeolum, but introducing Tropaeolum ciliatum to
my garden was one of the worst things that I ever did. It is a fast
spreading menace that is almost impossible to eradicate. If anyone
lives in a similar climate to the UK, make sure you only grow it in a
pot on a concrete base or face the consequences!

best wishes,

David Victor

PS for those of you that know (of) me, I've recently become the UK
National Collection Holder of Pelargonium Section Hoarea.
