Daylily This perennial once planted can live for years without you doing so much as look at it. The varieties to choose from run the gambit in size, shape and color but all are easy to keep going with only the occasional dividing (every 3-5 years). They self mulch, are resistant to insects and look beautiful in virtually any soil, any climate and can take both too much and too little water. What can be easier than that?
Daisy This wildflower-tuned-garden-staple is wonderful in any flower bed. The amazing thing about it is the more flowers you pick to bring indoors, for daisy chains or to find your true love (He love me, he loves me not, sound familiar?),the more it will keep blooming. It spreads by itself making more plants for you to give away to friends.
Black-Eyed- Susan (Rudbeckia) A kin of the Daisy this flower requires nothing much but your praise. It self-sows, is hardy almost everywhere and can take drought as only a wildflowers can. Brilliant sunshine-yellow blossoms will attract butterflies like mad and brighten up any garden
Rhododendron The king shrub of spring time, Rhodos, as they are affectionately called, do great in semi-shade but can be fine in full sun too. They like soil on the acidic side, so, if planted near evergreens which acidify the soil on their own by dropping needles, you needn't do anything for them. The occasional pruning will encourage more flowers but even without that they do beautifully.
Peppermint Once this fragrant and very useful herb is planted there is no getting rid of it even if you try so you may want to pllant it in a pot instead of right into the garden. It is as voracious and dependable as a dandelion and makes a great tasting addition to sun-brewed tea. Butterflies and bees love it too.
Hardy Hibiscus Growing to a six-foot tall shrub within a season with huge dinner-plate sized blossoms, Hibiscus can live quite happily in standing water. They self sow to the point you may eventually be sick of them but there are worse "illnesses", aren't there?
Sedum Sedum is the ground cover to plant where nothing else will grow. From the poorest, dry, clay, wet soil to sunny or shady places this plant will prosper with no help nor hindrance from you. It spreads like a carpet and bursts into bloom every spring with white, pink or red star-shaped flowers.
Daffodil It is the bulb that deer won't eat and we have to love if only for that reason. But there are other reasons to love daffodils. They come out in spring all by themselves to cheer us up and brighten our winter-weary souls. They only need dividing every few years but can also be left on their own if you initially plant them far enough apart in compost rich soil.
These are just a few of the easiest to grow plants that every gardener lacking in the enviable green thumb should have in their yard. If you can include these plants that pretty much look out for themselves you will be in a flowery heaven in no time and your neighbors will simply assume you do indeed have a green thumb. Which, of course, is the case. Your lovely landscape will say as much. Hope you enjoy your newly acquired green thumb.
