Rattlesnake Trail

I use the name Rattlesnake Trail somewhat loosely here, I intend for it to cover not only Rattlesnake Trail itself but also: the Rattlesnake Connector and the alternate route that runs parallel to the lower part of Rattlesnake on the east side of the creek.

These are the plants I have seen on these trails.

I have not necessarily seen them blooming on Rattlesnake Trail but I have seen the plants themselves, and seen them blooming somewhere in our trail system. Similarly the little blooming date graphs below the picture reflect the entire trail system, but should give a rough idea of what will happen here.
