Title: Digiplexis
I’m very intrigued by a new plant appearing in catalogs this spring.  Digiplexis,  a bi-generic cross between Isoplexis, native to the Canary Islands and Digitalis.  It is listed as hardy to zones 8-10, but I would need to use it as an annual here in Wisconsin, although I might try to overwinter it in my glasshouse.
 
My concern/question is that the plant apparently needs vernalization at temperatures below 50F (10C) for at least 4 weeks in order to set flower buds.  Few of the catalogs offering Digiplexis indicate if the plants they are selling are vernalized or not (or should I assume they are?).  One site selling plugs to commercial nurseries does address this, but I would only be interested in a single plant, expecting it to bloom this year.  If worse comes to worse, I’ll probably ending up calling the nurseries and speaking with someone in a technical capacity to answer this question.
 
Anyone here have any words of wisdom?
