We have 3/4 of an acre. My wife is a Master Gardner and she just grows unusual flowering plants. Nothing is food related, unless it is for the bees, butterflies, and humming birds, and other critters.
That is just part of some of the flowers in the front yard. The koi pond in the back yard is full of plants as well.
I put in the well 22 years ago to water the yard. 99 spray heads in 12 sections. Even in the dry periods I can water enough to keep everything green. She has some plants that don't like wet leaves, so in those areas we use drip irrigation. The water well has no pressure tank, it was put in for lawn irrigation. The valve opens up, and the pump starts, and is never pressurized more than the flow rate.
She changes out plants back there all the time. We can see the pond from the kitchen and dining room, and living room.
This is the koi pond.
