Seedling of the Year 2010
There are no definite rules for setting type for a plaque, but it would be best if you could get somebody with experience in graphic design, typography or printing to give you some advice. There are so many possible ways to set the type that it is difficult to advise you in a short response.
I would start "Awarded" with a capital A. I would probably not give "to" a capital T, and would not give "for" a capital F. But if you think it looks better then capitalise them both, not just one.
I would not put colons (:) after "Awarded to" or "for".
Perhaps the words "Pushpa Suresh" could be set in slightly larger type than "Awarded to/for".
I definitely agree that quote marks (") would not be suitable for the bloom name. It might be worthwhile seeing how "Bob Carran" looks in italics (Bob Carran). Italics are often used for the names and titles of things in print and it would be an effective way of indicating this on the plaque. Depending on the font used, italics can also look quite elegant, which may add something to the overall effect.
I hope this is of some help.
