Here's a picture of another bunch a Isis, same type as the first, but a little higher, closer to the house.
Was just out a moment ago, and found that the next height of Iris might be openin up in a day or two (cause it's gonna be real hot fer the next couple a days and) cause they're startin ta show a little colour through the head - first bunch a these higher Irises will likely be the same colour - a type a dark blue.
