Sharlee is a somewhat close match and is a rebloomer but has yellow shoulders which hers doesn't. Another close is Elsie Richardson which doesn't mention rebloom on the Database, but has the same haft marks. Try Googling for more pictures of both, but for me Elsie Richardson is more likely. There is more color in the standards but we know that can vary.
Does she remember where and when she got the plant? Sharlee came out in 1982 and Elsie R in 1992
