Hey Esshup alot of your warm season grasses and flowers should be fine if you do get rain and they germinate now. Not sure exactly what varieties you plant in your neck of the woods but around here most will not really bloom or put on much height their first year anyhow. As Lassig mentioned they are concentrating on roots their first year. Last year I did not even get mine seeded until August. The area I wanted to sow was in the runoff to the pond and I was afraid to till it up so I spent most of the spring spraying the cool season weeds then the warm season weeds. Looked terrible last year but it really put on a good show this year even with the lack of rain. Your perrenials should be ok but your annuals (if you planted any) are toast. My pond just hit 5' low and still no sign of the hsb.
