what type of flower

[Sylvie]

Marigolds can be different heights, fragrant and I think a meat chicken company boasted that their chickens are fed marigolds.

Most hardy roses don't have a scent.

Nah, there are LOTS that have a good scent. Blanc Double de Coubert comes first to mind (wonderful strong scent, can't kill with a stick), but there are a number of others, if anyone cares I could dig up a list I made last year. The very short landscape-type roses are a bit less apt to be scented... The Fairy (polyantha, but an unusually hardy polyantha, esp. if provided mulch or snow cover, you can grow them here in USDA zone 4/5) is awfully nice and decently fragrant to me.
