Forgot to add images for this thread.
I think I would classify this as more beige than yellow, it's HONEY SCOOP and has rebloomed for me the past few years in Nov.
I love this one! PRAETORIAN GUARD
RUSH CREEK I think can pass for the brown category, a rusty copper brown.
I took this shot at Schreiner's but hope mine blooms this year, so many to look forward to, only a few weeks away now!
