I keep all my landscaping alive. Occasionally Ill let the grass go awhile without water, but I usually try and keep it hydrated enough that it doesnt totally die out. Then in the fall it is alive enough to grow thick and green again.
We have 5 Hydrangeas, 1 Burning Bush, 6 Rose of Sharon, 1 Hydrangea tree, tons of Day Lillies, even more purple sedum, multiple Hosta, 1 Bloomerang Lilac Tree, 5 Dwarf Korean Lilac, 3 Potentilla, 5 Amber Jubilee Ninebark, 5 Red Prince Weigela, 6 Peoney, 3 Vsrigsted Grasses, 3Fire Chief Arborvitae, 1 Cherry Blossom (unsure which type) and 2 Coppertina Ninebark. Year 1 we had to replace a few here and there, but nothing crazy. Now they are all doing very well minus the hosta, which gets ZERO rain due to a double overhang -- and I just cant keep up with watering. Probably will replace with a more draught resistant bush this fall.
I also grow Jalapeno, Basil, Tomato, Blackberry, Raspberry, Chives and Green Onion in from May-October.
ZERO indoor plants, minus the Hydrangeas and Sedum we cut.
