To tell you the truth I do not know what Eremurus are, they are not bulbs but act like it. They would do well in that rich bottom sand! They really want good drainage and although we have sandy loam, if it isn't raised so they sit in standing water during our typical winter and spring weather and it does rot the roots, they will return from the crown and survive if rescued in time. Some have been moved to better drainage, flood deposits of gravel mixed with sand - on a mound, some are in raised beds and do very well. They dry up in summer here, we get virtually no summer rain, and form a dry crown with dry roots which keeps dry until spring, but we don't get blooms if spring planted here, we tend to have some heat waves in late spring and spring planted lilies do not do well here either. We cannot drag a hose out all over 40 acres to water late planted stuff and can no longer mulch. In a garden setting they may do better. Here is a picture of one of my Eremurus crowns, truly a strange looking creature. They won't look quite like this from other places, they are usually missing most of the roots.
I've been collecting a lot of bulbs and even done the unthinkable to some plants. I ripped a oriental poppy in half and the pieces seem to be living for now. And I was told they do not like to be bothered. I think this is the one I am suppose to be sending you. It needs some love before I can be sure it's ok.
