Purple Fountain Grass - Love this in a container with a lower flowering plant around the bottom. May just need to do a new pot! This is a heat lover too! Great for Texas.
Sensory Gardens: "Use plants that play on the senses, such as fuzzy lamb's-ear, textural succulents, or fragrant lavender." (though not many eat it, lamb's ear leaves are edible, and most fleshy succulents are edible)
Money does grow on trees...and on bushes and vines and groundcovers, too. With edible landscaping, saving money never looked and tasted so good! http://www.bhg.com/gardening/vegetable/vegetables/edible-landscaping/?socsrc=bhgpin042415ediblelandscapin
