Not sure what this poker is called, but it could be Wrexham Buttercup. I don't think that the photograph quite does justice to the strength of the yellow. Probably my best kniphofia, which is why we grow several clumps in the hot border.
Foxtail Lilies always impress visitors because they are not widely grown. There's no reason why not. Eremurus is quite a tall plant(5 ft), and here its hiding its untidy leaves behind a pink alstreomaria.
Penstemons are wonderful value plants - easy to manage and long flowering. Reputed to be tender, but we've not had any trouble. We don't cut them back until the spring though, (to about two inches from the ground) allowing the old foliage to give a bit of frost protection. More altreomarias behind.
