I have planted many rudbeckias over the years. Everything from the tall Gloriosa Daisy to the small Beckie but I've never tried Tiger eye. I find them easy plants to grow although they do take a couple of months to grow to a size to plant out. However once in the garden they take off and put on a gorgeous show. If you plant them mulch them well in fall and they may winter over. I'm quite a bit colder than you and I have had many winter over if they are well mulched.

Your tiger eye looks like another one I'll try. My favorite at the moment is Cappuccino Rudbeckia. large flowers of redish brown tipped in gold. It's a stunner. I also like Beckie for edging a border. It has smaller flowers on an 8 inch plant but it blooms profusely.

Yellow goes well with mauve or blue. Sprinkle some annual for-get-me not seed around in early spring when the frost is coming out of the ground. You'll never have to plant it again because it self seeds. Try Purple Zinnias or Snapdragons or go for white which goes well with any color. Whatever you plant make it a different shaped flower than the Rudbeckia

By accident I ended up with a short (3-4ft) dark leaf canna (unknown variey) and loved the mix.
