The early yellows (Narcissus) are gone, and now it's pink and purple (and mauve) season, at least in my garden, featuring Dianthus (pinks, lower left), Iris, Allium (chives), Lupinus, and Tradescantia (purple near the center, bright pink to extreme right). Not shown: Perovskia (Russian sage), Nepeta (catmint), Digitalis (foxglove). Photo taken June 12; today the clumps of low Sedum (in wall, lower right) showed visible yellow buds, and Alchemilla (ladies' mantle) was starting its chartreuse bloom. Warmer yellows, reds and oranges will become more common over the summer, with Hemerocallis (daylily) and various daisies taking the lead. This seems the most common color progression. Perhaps you have a different scheme?
