It was growing in London on waste ground but may be a garden escape as the plants were very close to gardens on all sides. About 18 inches high. Single stem. 3 drooping flowers just about to open. Lots of straight, narrow, dark green leaves up the stem with very striking white mid-rib.

I have a small garden in Rome, Italy. Some open soil, some concrete, some paved. Temperatures in winter occasionally down to 0°C. Summer temperatures up to 40°C in the shade. There are never watering restrictions but, of course, there is little natural water for much of June, July and August.

Sorry, can't count. Looks like 4 drooping flower heads.

Looks like Caper Spurge Euphorbis lathyris to me. Poisonous, and the seeds are jet-propelled...

I am establishing a garden on Waiheke Island, 35 minutes out of Auckland. The site is windy, the clay soil dries out quickly in summer and is like plasticine in winter, but it is still very rewarding. Water is an issue, as we depend on tanks. I'm looking forward to sharing ideas. Caroline
