For a real garden showstopper, look no further than the gorgeous flowering crabapple. The Royalty variety produces purple-meets-crimson flowers, which are striking all on their own. The addition of a deep, dark foliage adds more richness of color. Sherlock says that the flowers and fruits produced by the tree are very attractive to bees and wildlife. Their size makes them a great focal point of any garden, though they're a particularly great pick for smaller yards.

The seeds of these trees are quite easily located—inside the fruits they produce, of course—but note that they can take about three to five years to produce flowers. It's well worth the wait if you have the patience.
