Place the stem in the cube (figure F). Because geraniums have fewer leaves to strip back, you'll need about one inch of stem for the plant to root correctly. Sprinkle the plants in the rooting cubes with water about three times a day. Occasionally mist the cuttings as well. In 6 to 8 weeks, the cuttings are ready for transplanting, with good root systems developing underneath the cubes (figure G). Take care removing the cubes so that you won't damage the roots. Simply break the cubes off gently. Schroeder uses about two to three cubes per pot when planting. Place the plant--still in its cube--in the pot, but be sure to leave the top of the cubes exposed. Otherwise, the plant stem may easily rot.
Harvest edible flowers in the morning after the dew has evaporated. Keep the flowers cool until you're ready to eat. For the best color, flavor and texture, use the flowers the same day as they are picked.
"Edible flowers are becoming true American beauties, expanding a gardener's palette in more ways than one," says James. But remember...don't eat the daisies, or any flowers for that matter, unless you know they're edible. And if you have never used edible flowers with food, or have no experience eating flowers, start with small quantities.
Bear in mind that flowers grown in different regions will taste different. "Soil type, fertilization, temperature variations and other environmental factors all play a role in the flavor of the flower," explains James. "But no matter where you grow them, edible flowers can make a tasty addition to any garden."
