Smart Gardener - best garden planning app I've seen by far. Helps you plan your perfect garden according you your area and number of people in your household. Gives you weekly to-do lists so you won't miss a beat and helps you stay on top of tending.
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
