Peony ‘Karl Rosenfield’ has bright, crimson red, double flowers on open bushes. It is noted for its vigour and prolific 15cm blooms. It opens mid to late season.
Why not spoil yourself and enjoy an abundant spring to summer display of intoxicating loveliness. Peonies look exotic and temperamental and yet they are remarkably hardy and grow well in cool to temperate Australian gardens.
The exotic flowers of Peonies have been cherished since the 5th century and during their long and illustrious history, Peonies have been the flower favoured by Emperors and Gods. Fortunately, they are now accessible to the common gardener.
Peonies are vigorous, long lasting garden plants that will likely outlive with opulent blooms that make wonderful cut flowers. Once established, you can enjoy up to 50 can open in a season.
You will have to be patient to enjoy the flowers of Herbaceous Peonies as they establish their roots – they have big blooms to fuel. Mature plants can have a rootball that weighs almost 30kg and stretches up to 90cm. But the wait will be justified for many years to come as they are extremely long lived.
Peonies are heavy feeders, so you need to fertilise them regularly. They like lime, and lot’s of it, so be sure to indulge them. Plant your Peonies just beneath the surface with around 2cm of soil covering them. Too deep and they won’t flower for you.
Peonies need cold winters (3-7C nights at least for around six weeks) for best flowers.
If your climate doesn’t get that cold, but you still want to try your luck, Tree Peonies need a bit less cold. As a general rule, if apples can grow in your climate, so can Peonies. To give them the best chance in warmer climates you should seek out a cool spot to give them the best chance, with shelter from the hot afternoon sun and you should mulch well (but not too close to the tuber it needs to remain shallow). If they aren’t going dormant, to have the winter rest they require, you can force them into it by cutting them back hard in early winter.
