Fillers I used this season:

Statice - Seeker Series
Basil - Sweet Dani (lemon)
Dill - Dukat
Yarrow - Colorado
Grass - Frosted Explosion
Sweet Annie - (unscented)
Peony leaves
Hydrangea leaves

Anything green that holds. Slim pickins' the last couple of weeks, but fun to "find" late season fillers!

My favorite plants for fillers are:
Sweet Annie (unscented)
Dill
Frosted Explosion grass

Pitt / Indiana

Too many fillers by season to list.
Mixed bouquets sell better than monotone.
Favourite plants for cutting are :- Varigated Periwinkle, Eucalyptus and varigated privet

One thing that I have been liking this year for greenery is baptisia.

Some of my favorite fillers other than plumed celosia & statice are:
cinnamon basil, eucalyptus, dill 'Hedger'

Unscented Sweet Annie is a new concept to me. Which artemesia is this?

Martha, I planted a scentless sweet Annie (Cramer was in the listed name) for several years. I could not find the seed in 2011 and have not been able to find it in any of the 2012 catalogs. This was one of the best fillers I had and I really miss it! Curious to know if anyone knows where to find it. I ordered it from Cramer's one year and Johnny's another year. Sadly, it came up volunteer very sparsely, but I used what I had! ; ) Pitt

Was it Cramer's Yardstick, do you think?
