Answer 1

Cocosmia hybrids or knifofia (red hot pokers, you can get dwarf varietys), i think i spelt it right lol.

Answer 2

Dahlias are late flowering, you elevate the roots for the iciness and replant next July. There are multiple distinct shapes, colorations and sizes. One plant that is going fairly properly with roses is Lavendar, i ought to apply Munstead Dwarf. The fragrance facilitates keep aphids off the roses and the color scheme is often complimentary.
