Not really sure what gloxinia are; the reference said they grow in ‘summer gardens’, which leads me to believe that’s some place where there are winter gardens too, which is an impossibility in my neck of the woods. This is a companion to ‘Pansies’; I actually used the exact same leaf colors in both, though these seem more successful; 8×10 on Coulorfix; Mount Visions plus a few strays (the green in the background is the Sennelier 179); please let me know what you think. Thanks for looking; Happy Holidays. Neal
