One morning in mid-April – the warmest of the month so far, I had the pleasure of visiting our ex-chairman, Jillian S, to see the display of her stunningly beautiful tree peony flowers. These are well established shrubs with one or two still in bud and the rest nearly finished flowering, apart from the 2-metre species Paeonia delavayi, which is covered in red flowers and buds.
Every gardener should possess at least one tree peony – just to experience their few weeks of fleeting beauty – and, of course, their very handsome and large foliage, which is an added bonus to every garden for many months of the year.
I noticed that Jillian’s tree peonies have or had far more buds than mine, which is about 20 years old. Why is that? Jillian tells me that she has always had a strict policy upon purchasing any plant, including the tree peonies, and that is to immediately repot the plant with one-third multi-purpose and two-thirds of soil from her own garden. Only when the roots have established themselves in the new soil mix does Jillian then plant them in her borders. This method ensures there are fewer plant losses as the roots get the chance to adjust slowly to the change of soil, with the outcome being much stronger and robust root systems and, ultimately, stronger and healthier plants. And, that is the best gardening tip I have ever received!
Jillian tells me that all her peony varieties (Paeonia x suffruticosa) arrived as ‘freebies’ during 2009 and 2011, as special offers advertised in one of our major newspapers. They would arrive in good condition: an 18” stem with two or three branches and a sturdy root system of approximately 9” in length. These would, after potting on, be left for around 9 months to 1-year before being planted into a bed. In springtime, from then on, when the soil is still moist, a mulch of homegrown compost is added around the base of the plants to retain the health of these specimens.
Over the years, Jillian has diligently and systematically recorded in notebooks all of her purchases. And in one of her notebooks she has found her notes on the exact dates the tree peonies arrived:
4th June 2009: Hai Huang Yao (yellow) and Huang Hu Huang Dao Jin (cerise with white splashes).
11th November 2009: Wu Long Peng Sheng (pink/red) and Honxia Hu Hong (pink).
23rd April 2011: Wedding Day.
Peonies prefer morning sun and dappled shade if possible and Jillian’s peonies are perfectly positioned, growing on the north side in the spring garden, some protected by the apple trees. Very little pruning is necessary but I notice that Jillian’s tree peonies are more elegant than my shrub, so a little judicious pruning on my part would not go amiss!
