"Due to the early, and quite warm weather this spring, some Red Emperors are flowering on short stems. Early warm temperatures can cause the flowers to form and open earlier than normal. The mild temperatures hastened flowering, before the stems elongated or lengthened. If we had seen a few weeks of 40-50° daytime temperatures, we would likely have seen taller tulips. However, temperatures in the 70's cause the flowers to form, rather than long stems."
