'Megan' appears in several listings on HelpMeFind, but I can't find a UK supplier.
Maybe someone else can find a source.
Meg

Miss Megan was hybridized by Vernon Rickard of Almost Heaven Roses. It is a beautiful medium pink and has good form. I don't know if he can ship to the UK. His web site is: www.almostheavenroses.com. His phone is: 704-732-4787, Fax: 704-748-2627

Ok. I would be willing to buy and ship you the miniature rose 'miss megan' to the UK; if you would buy 'tiny jack' in the UK and send it to me in the US. I would send you the US plant inspection lable that is required to import plants from there. Does the UK inspect plants from the US?

Does anyone have a picture of "Miss Megan" ?

i am also looking for a miss megan rose. if anyone can help me find a place where i can order one, i would be extremely grateful!! thank you

As the post above from SandySC stated, it was hybridized by Vernon Rickard who owns Almost Heaven Roses and it is listed on their web site.
