You are quite right. (I love a person who looks deeply into a rose). The patent says "Filaments.--Slender; reddish. Anthers.--Well developed; yellow". We'll change that description.
Would you maybe like to share your list of red or pink filamented roses with us? That would be so nice to have! I'm quite fascinated by these, as I have one myself that still needs identification.
You show 'Playgirl' floribunda as being up to 18" in height. Seems to me it is much larger than that. Mine is in a pot and is at least 2' high. Please advise? Also, what is general width?
