I have planted only a few Zinnia seeds this year and they have began to bloom recently. The bees seem to like them and will sure plant more next year. When you move to a new house there is lots of things to be done first and for that reason I didn't focus much on planting more for the bees but this will change next year.
As a matter of fact I will be planting various perennial plants this autumn which need cold stratification. Our farm is ment to be created as a Bee Sanctuary flowering from early Spring to late October.
Mono-crop agriculture is damaging our eco-system and bees indeed need all our help in form of planting lots of flowering plants, bushes and trees from them. This is not our end task but rather an action of conservation until we ban mono-crop agriculture and have an agriculture system based on local small-scale farming based on biodiversity and no pesticides and no tilling. Remember that all bee issues stem from the industrial mind! We need a paradigm shift, utter paradigm shift! Direct knowledge is the best tool toward awareness! To be aware humans must see it with their own eyes. Make sure they see it, but be gentle with the ignorant :) We were all ignorant at one stage and still are for certain aspects of life, death and the Universe :)
May you bee buzzingly happy at heart!
