/// Tanzanian-born Mrs Sargeant, 50 - a former chairwoman of the Society of Garden Designers said 'I don't come across any other black garden designers when I'm out and about. But that doesn't mean black people aren't interested in gardening and design. ///
/// 'What we're offered is very much the typical English garden that is perhaps not so relevant to people of multiple cultures and ethnicities that live in Britain.' ///
I've got news for you dear, Chelsea is in England, but that doesn't mean that at the Chelsea flower show, we don't see just 'English' Gardens but also 'Italian Gardens' 'Japanese Gardens' etc.
But I must admit we don't see many 'African Gardens' or 'Indian Gardens' perhaps it is because not many in those countries are as fond of gardening as we the English and others are?
