I don't know, but I'm going to venture a guess on this one. Hortico is famous for saying they have one rose and then delivering a different rose with a similar name. One year their website advertised the Florist rose Texas (a yellow hybrid tea), which I ordered because I thought it would be fun to have both roses named Texas (the mini, which I already had) and the hybrid tea, which they supposedly were selling. NOT! What they actually sent me was another plant of the mini -- which was not what was on their website.

This year, the same problem. Their website says they have the rose "The Twins" which is supposedly an orange shrub. However, what they sent is probably "Twins" by Lens, a polyantha. (I haven't seen a bloom yet on this new plant, but the small leaves are telling me it's a polyantha).

I have heard others discussing the same type of issue with them. So, if I had to guess, that's probably how "Mothers Day" became Mothersday. The same bad website copy checking, for which this company is infamous.

Pat I loved your compilations etc. George Robert Knight is / was a distant cousin. I was going to work on a full list of their roses. Any interest?
