Yellow Tritoma, or "Red Hot Poker"
This interesting flower is now undergoing observation in Mr. Burbank's garden. There are marked variations in color in the flowers, as will be shown in a subsequent picture, and these appeal to Mr. Burbank as offering opportunities for modification through selective breeding. Hence the attention that is now being shown this rather spectacular plant.
