Happy Birthday coughingbear. I suppose you're in Hong Kong and won't read this but the wishes are the same.
Some people don't like Hebes. Christopher Lloyd thought this was because they associated them with memories of seaside boarding schools, but he was showing his age there. I don't care for what I think of as 'municipal' Hebes; large shrubs with big leathery leaves and rather dull purple flower spikes. There are far more varieties available now, all prettier than those boring ones, and small enough for any garden. The one featured here today makes a neat little bush with wiry stems and fluffy pink flowers which last a long time. I think it's 'Wiri Dawn'. Give it a haircut after flowering; it will stay small and neat and probably flower again, perhaps even in winter.
