Hybrid lactiflora, Garden Peony 'Mikado'

Introduced by Peter Barr in 1893.
Per the 1928 Lee R. Bonnewitz Iris and Peony catalog of Van Wert, Ohio:
MIKADO (Barr). A ...Read Morevery deep rose, or medium red, Japanese Peony which blooms early, grows on tall stems, and has splendid laterals, giving a longer blooming season than almost any other variety. This Japanese Peony has been growing in the United States over thirty-five years, and is undoubtedly better known than any other from the "Far East." Although in commerce so long, it continually increases in popularity, and is now being sold at a higher price than in former years. We do not know when the supply will equal the demand. $2.50
