all - just returned from sunny holiday to see this
Laurie - you may have to do the tropaeolum from seed and even then source from UK. Pretty sure Plant World Seeds carries this. While it has never flowered here in my Zone 4b garden, (it's something like a Zone 8 perennial
)it does send out gorgeous blue-leaved trailing stems mid-Spring; may go in to hibernation early Fall though. It is a small bulbous plant so easier to grow in a zone or two higher if planted well.
