Hi Marylin,
My answer is late, but I don't find the time to look at all these subjects on our forum. This one is particularly interesting for me, because I tried too planting eremurus coming from my previous garden close to Paris. And I planted 3 bulbs in a semi-shaded bed with watering during summer. I only had them flowered once perhaps 4 years ago. Since then, they are dying each year after each year. this spring I only had one rosette of foliage. Law de Jaeger (from Bulb'Argence) came and visited me 3 years ago and told me I should plant them in my mediterranean bed on top of the small hill and in sunshine, never watered even in summer. And it was worst. The foliage has almost disappeared and I don't even know if they are allways under the ground. So, it is a complete failure. I can't understand why I got a nice flowering season only once. Here, in Montpellier, we have cold in winter, I can tell you. -4°C several nights in november.
