This is largely from a post I did in 2013 with some updates. Seeing the colour in my garden and watching the single flowers close up for the evening I decided to buy some more seeds for next summer (I hope I can find the space to do them justice) I opted for ‘Copper Swirl’ by TM and for an extra 99p I got ‘Golden West Californian Poppy’ thrown in.  I am tempted to sow half of each packet shortly although the blurb on the packet suggests waiting until Feb or March next year.

‘I like a brash colour in the garden and you can’t beat my favourite annual Californian Poppy. Eschscholzia californica is a bit of a mouthful but Californian Poppies and their family are well worth the effort.

The Californian poppy is an easy to grow hardy annual, which thrives in well drained sunny positions.

Growing Eschscholzia Tips and Hints.

• Eschscholzia doesn’t like being transplanted at all, so it is best to sow in open ground. Eschscholzia have long soft tap roots that are easily damaged so take great care if you have to transplant them.
• The main criteria for growing the Californian poppy is a well drained soil and sunny exposure.
• Eschscholzia doesn’t need feeding and can thrive in the thinnest of soils. Gravel gardens are ideal.
• They can be sown in October or early spring.
• If they enjoy the conditions of your garden, it will freely self seed; it can even become a little invasive, although it is fairly easy to weed through just a light raking.
• It is worth thinning the seedlings so that individual plants become stronger.

Varieties of Californian Poppies

• When sowing Californian poppies I would recommend choosing single coloured varieties such as Golden Values, Red Chief, Sun Shades or the cream coloured Milk Maid.
• The orange is my favourite colour and Rosebud Orange is a ‘dazzling orange, extra large, double and semi-double, rose-bud like blooms smother bushy, compact plants with silvery-green, feathery foliage. Creates an eye-catching display, when sown as drifts in borders in any garden soil, or in large containers on a sunny patio.’
• For a mixed colour range try Fruit Crush ‘A captivating mixture of upward facing blooms in a bold blend of citrus and berry shades. These dainty hardy annuals are tougher than they appear and positively thrive on poor, dry soils. The papery flowers attract bees and hoverflies, and make excellent, if short-lived, cut flowers.’

Californian poppies Poppies are available from Thompson & Morgan.

Californian poppies grow well from seed sown direct into the ground.
