We admit it, there are times when the sheer gorgeousness of a tropical plant overrides common sense, and we bring it into the nursery anyway, to be enjoyed throughout the summer as an annual. Mandevilla 'Sun Parasol Pretty Pink' is one of those specimens with clean, glossy green folige and large, intensely pink blooms that just keep coming all summer long. This beauty loves the heat and sun, and can be grown up a trellis or in a hanging basket and left to trail. For those up to the challenge of overwintering mandevilla, plant it in a container that can be brought into a heated greenhouse or even indoors when the temps drop below 50 degrees. It won't need much water, and may even lose its leaves, but do watch for spider mites and other harmful critters.
