There was a new yellow and purple striped flower shown at the 2013 Flower Show.
What is the name and where can I purchase it?
Answer
Marilyn, are you thinking of Primula 'Blue Zebra'? This was one of the plants featured at the New Plant Showcase on the show floor at the 2013 Flower Show.
Attached is a pdf of Virginia Smith's Inquirer column, in which 'Blue Zebra' is mentioned.
"Breeders return to the roots of the PHS Flower Show."
This is a very popular plant this year. You may want to start with Mostardi's Nursery in Newtown Square (mentioned in the article). If they no longer have it, consult the Hort Couture web site. They have a map you can search for retail outlets of their plants. Hort Couture sells to the trade only, not to the consumer.
Hope this helps!
