Tropaeolum speciosum close up

Like it, have had no luck growing it up to now plant died and seed did not germinate

Think it needs heavy soil and to be grown up a conifer of some kind. As with Clematis its roots need to be in shade and its head in sun. I have managed to germinate the seed by sowing in ericaceous compost, covering the seed with pine needles and left outside all winter in order to stratify the seed. Unfortunately however I did not manage to grow them into flowering size plants.
