Friday Fabulous Flower - Prickly subject

This is a native plant to Lincolnland and it grows naturally fairly close by around the Havana sand priaries to the SW of us.  This plant is tough as nails and you just need a sunny, well-drained area to grow it.  Basically this is a near prostrate succulent shrub.  The flower is fairly large and certainly is part of our unintended theme of big yellow flowers.
This is a prickly pear cactus, Opuntia humifusa.  This image also shows the modified leaves quite well to the left of the flower.  These will not persist.  Sometimes you see plants where the flowers have a much redder center, but the smaller bees (green ones TPP usually associates with leaf-cutting) was observed just wallowing in all those anthers.  Regretably the flowers do not last long, but a plant can flower prolifically with lots of flowers.  This is a first time event for our gardens  and the plant a relative newcomer (3d year).
