Oleander -- Nerium oleanderIt's a good bet that the plants growing in highway medians are durable. Fast-growing, evergreen oleander is a favorite with its beautiful flowers in white, red, pink, salmon and yellow. It's highly toxic, so don't plant it if children or pets are a concern. This tough plant survives drought, scorching sun, heat and exhaust fumes along the highway -- just imagine what it can do in your yard.
