I think Heather is very close the Vanda Elizabeth does look like it. There are millions of orchids varieties and many can be difficult to procure as cut flowers. Various types bloom at different times so when they are needed could matter. Also be careful when requesting a color - purple vandas are in many shades from perwinkle blue to dark plum- this color looks like some of the "red" that are offered from the Dutch market.
The description for the Vanda Elizabeth is plum red, so be careful when ordering, request a picture ( although not prefect for coloration) it will hoepfully get you in the color range you need. Purple is not always purple, if you know what I mean.
