Scotland's Flowers in Her Heraldry

[Bugbear]

Over in my Scottish wildflower thread, I mistakenly asked a question about twinflowers in heraldry:

ThistleDown, thanks for posting and discussing the flowers. It's actually my fault for looking things up on Wikipedia.
http://en.wikipedia.org/wiki/Linnaea
It says about Carl Linnaeus under the "Cultural references" section:

Linnaeus took Linnaea borealis as his own personal symbol when he was raised to the Swedish nobility in 1757. In his Critica Botanica (1737), Linnaeus had used Gronovius' name Linnaea as an example to advocate the use of commemorative personal names as botanical names:

Perhaps one of the experts of heraldry will stumble across this thread and answer the question.

Anyway, I thought it might be interesting to ask for examples of flowers that grow in Scotland that also appear in Scottish heraldry?

And, if by chance, anyone happens to know the answer to the question: does Wikipedia mean that flower was used in Carl Linnaeus's arms?

Thank you.
