Brown isn't a color that I thought of much for semps, but it works quite well and there are several quite nice cultivars out there.
So... whaddya got that's brown? Or brownish
anyway. Brownish-orange, brownish-pink, brownish-green... whatever. Here's my 'Nouveau Pastel' which I chose specifically for it's brown coloration. Just like me, it seems to have really disliked the recent 100+ degree temps.
