Q.Small irises
About 2 years ago we planted over 100 dutch iris bulbs in about a 60′ area next to my garage by our fire pit, facing east. Many of the flowers poke through every year, but never get more than about 10 inches tall. Several have very small flowers bloom, but nothing like I was expecting. Are the flowers still trying to get established, or am I doing something wrong. Could they be getting too much water
Dutch iris are often treated as annuals. After one blooms, the main bulb is done blooming but lives on to nourish bulblets. These baby bulbs take several years to reach blooming size. Here is more information: https://www.longfield-gardens.com/article/All-About-Dutch-Iris
