The Dwarf Pomegranate is one of our really unassuming plants. The tallest plant is only about 60cm (2'), has small leaves and can easily be overlooked. However when conditions are right, you will be rewarded with beautiful orange-pink blooms (often red). These will eventually turn into little pomegranates. I've opened one up and it was filled with seeds. There was very little fruit so they appear to be inedible (even though they supposedly are). They are however a very beautiful plant for a small but visible place.
These pomegranates are hardy from zone 7b - 11. They grow well in full sun but partial shade will also work (with less blooms). They are very drought tolerant and perfect for container gardening if you often forget to water. The seeds are apparently fertile so I might try and start some this spring. Otherwise they can also be propagated by cuttings and air layering.
