Abstract
Acer rubrum (red maple) foliage may obtain a deep scarlet color. Crocus vernus may display deep purple petals and yellow pistils. Stains from each of these may be extracted by processing targeted portions. One technique is to harvest the material, rinse the harvested material in water, immerse in 70% isopropyl alcohol until the alcohol leaches color out of the material, filter a liquid portion, dehydrate, and re-dissolve in 20% isopropyl alcohol. This extract may then be used to stain tissue.
