The heavy rains caused many plants to collapse. The variegated grasses are always the first to go. If I'm patient enough, I'll try to cut the stems above a leaf. so the blades don't look chopped off. Sturdy plant supports can push smaller grasses up but you have to do it quickly before the plant starts reaching for the sun and the growth becomes distorted. This happens very quickly, usually within two days. Cutting off the older coneflowers wil lighten the load and help plants stay upright.  I've begun shearing off the tops of coreopsis to remove the old flower heads. It can be tricky since new buds are coming up, so you may have to sacrifice some. 

If you haven't pinched back your annuals, and they've begun to look leggy,

now is the time. Some annuals like plectranthus, sweet potato vine, helicrysum, and some of the newer petunias tend to more aggressive and can take over a planting, quickly smothering out other better behaved annuals. If a trailing plant has dried out, you'll have to cut back to green growth. They will quickly rebound, as long as you step up with the watering.
