Poppy love: Monty Don adores promiscuous poppies, with their beautiful blooms and stunning seedpods. Here he highlights his favourite types of all…
- Monty Don says 3,000 of the 17,000 seeds poppy flower produce remains viable
- British gardening expert’s favourite is opium poppy, Papaver somniferum
- It grows in almost any conditions and reappears year after year with reliability
Monty revisits one of his classic books, Gardening at Longmeadow, in an occasional series.
For all their massed effect of brilliant colour when growing in a field or on a bank, annual poppies – which are starting to flower at the moment – have an individual delicacy that I adore.
They can be extraordinarily prolific. Each poppy flower will produce about 17,000 seeds, of which some 3,000 will remain viable and dormant in untilled ground for at least a century before bursting into flower when the ground is disturbed and the seeds exposed to light.
This tendency to wait until ground is tilled explains why poppies will grow seemingly from nowhere when a garden is cleared for the first time for years.
British gardening expert Monty Don shares his advice for growing different types of poppy flower. Pictured: Pink opium poppies (Papaver somniferum)
Breeders have harnessed its promiscuity to select garden strains with the red shifting through every shade. ‘Ladybird’, with black splodges, has the reddest petals of all, shining as bright as a ruby as it catches the evening sunlight in the Jewel Garden.
Perhaps the most significant deliberate domestication of field poppies came in 1880 when the Reverend Wilks, vicar of Shirley in Surrey, noticed a single one in the vicarage glebelands with a white base.
He liked what he saw so collected the seed from it and eventually bred the strain that we know as Shirley poppies, which have white, rather than black, bases to the petals. They are more delicate and subtle than the field poppy, although tend to revert to field red unless you carefully collect the seed of the paler, pastel shades.
The opium poppy, Papaver somniferum, is my favourite type, and as well as its superb flowers it has wonderful foliage while the leaves are young, and some of the most beautiful seedpods in the natural world.
It grows in almost any conditions and reappears year after year with reliability. The leaves are a fabulous glaucous colour, and as lush as any lettuce, and the stems grow up to 1.5m tall in rich soil.
They look especially good with roses, but you can hardly go wrong with them, whatever they accompany. The flowers can be any colour from white to a deep purple and range from being single, fringed or arranged in multi-layered frills.
Among the opium poppies, the peony-flowered types are my favourites of all, with their petals like crumpled ruffles of shredded silk. Others have cut fringes or create such a mass of petals that they are almost circular.
‘Black Peony’ has an intense plum colour and, at the other end of the palette, ‘White Cloud’ is perfect for a white border. I also love the crested heads of the Laciniatum type that look like headdresses for a day or so before they fully open.
Opium poppies are worth growing for their seedheads alone and unless you are collecting the seeds of a particularly lovely one, leave the plant in the ground for the urn-shaped fruiting heads.
If you do want the seeds, tie a piece of twine around the stem as soon as it flowers (you think you won’t forget which one it is but you always do) and cover it with a paper bag when the last petal drops.
Always sow annual poppies in situ as they hate being moved except when tiny.
Either scatter the seed and let them grow where they land or sow thinly in zigzags so you can differentiate the emerging seedlings from weeds.
How to grow pelargoniums
Monty said pelargoniums grow rapidly, when repeatedly repotted into slightly larger containers before flowering
- As a rule, the harder pelargoniums are treated, the better they’ll flower, as they only bloom when the roots are constricted. I keep them in small terracotta pots and don’t feed them at all.
- Make a plant grow rapidly by repeatedly repotting into slightly larger containers before it flowers.
- If a pelargonium has become too big, cut it cleanly across, 30cm from the base, and it will regrow vigorously.
- If the leaves are tinged orange or yellow, the plant has been overwatered – let it dry out totally between waterings.
- Cut plants back to half size in autumn and keep them dry, cool and frost-free over winter.
- In May, give them the sunniest spot you have and water weekly.
