Rogan, I like your choices – those are plants most of us would be proud to flower. Tecophilaea has flowered here, my Worsleya have years to go before blooming, my Tropaeolum azureum is balky; I’m not currently growing Lapageria, but I’m sorely tempted to try again using my protected cold frame. But that’s only four: you only listed four, not five. That gives me the inspiration to ask the rest of you to jump in and name a fifth to complete this quintuple crown of horticulture. For me, a suitable fifth would be Paramongaea weberbaueri or one of the forms of Iris persica or some of the fabulous oncocyclus irises or … there are too many candidates! How about the rest of you? For that matter, why not give some other lists of five trophy plants?
