Hi, another non-californian answer: R. coultri is slowly starting to be offered in Germany, here with the winter being cited as the critical time. Mine was planted last year in the spring, had one flower the first year, so I thought: OK, give it time to establish. Winter was OK, plant lived through the unusually warm January, froze back to the ground in February but came back strong from the roots by beginning of April. That's when we had another weather anomaly, Summer starting right in late April (up to 29.7°C) and nearly no rain from then on up until a few weeks ago, which is highly unusual around here. I tried my best to keep everything watered (I expect my bill to shoot through the roof), but several plants I thought drought tolerant actually struggled. My Romneya only produced a bush of those nice silvery leaves (about 1m high, 1.5 m across) but never set flowers - I'm actually under the impression, it was too dry while too hot for it, average daytime maximum for June to August was around 30°C with 10 days reaching above 35°C. So: was it wrong to water? Greetings from Germany! Martin Am 16.09.2018 um 01:46 schrieb penstemon: >> I ask Californians for some information on this huge poppy with some >> trepidation.
