Dr Greveaux is a classic double scarlet paeony. It is a vigorous grower. Herbaceous paeonies grow to about 1 metre with glorious rose-like blooms and make a great garden display. They are also suitable for growing in large tubs and are good cut-flowers.
Herbaceous Paeonies prefer a well drained soil with well decayed manures added. Plant in a sunny or semi-shaded position, can be left in the ground for many years. These plants may be pruned back to ground level in late Autumn/ early Winter.
Herbaceous Paeony rhizomes are planted during the Winter months in a rich, well fertilized, well-drained and slightly alkaline soil. Plenty of compost or well decayed manure with blood and bone is recommended with a little lime added beforehand. Plant the rhizomes in a sunny or semi shaded position 60 cm apart with the eyes just below the surface. Remove the old flowers. Try not to harvest too many cut flowers when the plant is young and trying to establish itself. It is best to wait 1-2 years. Paeony roses are best left in the ground for many years, although the rhizomes can be divided/transplanted after a few years.
