Pomegranates? Really? Last summer I planted a ball-shaped dwarf pomegranate (Punica granatum 'Nana') in the center of a round feed trough. It sailed through the winter, holding onto its leaves and its looks through the coldest months of the year.
I surrounded it with tulips for spring, underplanted with ruffled, cut-and-come-again lettuces in late spring and early summer, followed by basil later in the season. The pomegranate budded up in July, and opened its bright orange-red flowers in September. It's brilliant little blooms are still brightening up the garden well into October.
Fruit? No chance in my north-facing Langley garden, but the shrub is well worth growing anyway for its utility as a small, sturdy, late-flowering evergreen.These sweet little shrubs need full sun, regular watering, grows (slowly) to three feet tall and wide, is very dense and takes well to pruning. Oh, and it's deer-resistant (that I haven't tested out yet....)
