The deeper pink of the landscape rose pulls out the highlights of the pink edging of the foreground rose. The spiked leaves of the iris contrast well with what looks like more of a fern or at least narrow leaf plant in the far back. A large bed with this combination would be awe inspiring. Maybe that is what you already have - cannot tell by this particular picture. Thanks for sharing!! Inspires me to plant some new rose beds this year with a combination like this.
