You don't need a quarter acre paradise. The average urbanite can create their own riot of colour outside the front door.
Whether you live in an apartment or sprawling villa, whether your thumbs are green or you're a convicted plant killer, a potted plant is always an option.
Arm yourself with a useful book, put on the appropriate garb and flex those wannabe green fingers.
If all else fails, and hand-rearing blooms from seed really isn't your thing, you can always settle for a few fakes, a refreshing drink or read, and a great gardening outfit.
