Buy Crambe cordifolia greater sea kale: Huge dark green leaves and fluffy white flowers

This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.

    • Position: full sun or partial shade
    • Soil: deep, fertile, well-drained soil
    • Rate of growth: average to fast-growing
    • Flowering period: June to July
    • Hardiness: fully hardy

      Billowing clouds of tiny, white flowers float above huge rosettes of deeply cut dark green leaves in June and July. A favourite plant of Edwardian garden designer Gertrude Jekyll, this perennial looks magnificent at the back of a sunny border or as part of a cottage garden scheme. The tiny flowers, attractive to bees, are a perfect foil for large-flowered plants. The leaves smell strongly of cabbage and the plant needs space to spread out.

    • Garden care: Cut back the plant to ground level in autumn and apply a generous 5-7cm (2-3in) mulch of well-rotted manure or garden compost around the plant in spring.

Notes on Crambe cordifolia

"Tall branching airy heads of tiny, white flowers on stout green stems reach out to the sky every June - these are replaced by tiny rounded green beads"

Bees and Butterflies love this


This is a tall member of the Kale family - and I mean tall a good 5' and some and it's wide so needs plenty of space at the back of the border in a sunny position and then leave it to it - and it really does attract bees, butterflies and hoover flies. Being white flowered it really compliments other colours in front of it.

A Cloud of white flowers


I saw this plant in a café garden and had to have one. It was HUGE and full of tiny white flowers. I keep bees and I'm hoping that they and butterflies etc will like it too. The plant has so far over wintered outside and looks ready to burst in to action. It is a Brassica and I am aware that I will have to protest it from caterpillars slugs etc. That might be a problem!




Protect from pheasant!


Sat outside of greenhouse, waiting to be planted, saw a pheasant digging at the surface. Had good root system , so planted with an upturned wire hanging basket, but no show at all. Suppose the pheasant ate the growing tip



love it but so do the cabbage whites so will remove it.


A very effective plant for a big space but was destroyed to lace by cabbage white caterpillers so will remove them.

Nice healthy plant


Good quality plant, budding up nicely for its first season.




Don't cram your Crambe!


Crambe cordifolia needs space to spread out its large leaves. Mine is at the back of the flower bed. It has a very attractive architectural presence and puts down long roots, so avoid moving it if possible. The sprays of white flowers are lovely. Slugs do head for Crambe's leaves, so take precautions early in Spring when the growth starts again. Dies down in Winter. Last year I cut out the lowest leaves to allow air into the plant.

The real thing!


I have previously taken Crambe cordifolia root cuttings in January so to have two plants, if a bit small, was good. The large green leaves were shredded by snails and insects but I persevered but it didn't flowered. 2017 will be its 'coming out year' and I have great hopes plus snail/slug pellets - watch this space. One plant is in my garden the other had to be rescued from my son's garden where I will reposition it soon in a better spot.

Attractive to caterpillers


Everything was going well with the Crambe - Crocus gave good information and the plant was growing really well at the start of the season. Then disaster - struck by an attack of caterpillars and it was stripped to the bones over a weekend. Having dealt with the monsters, the plant still managed to re-grow and look good with some tlc. Unsurprisingly there were no flowers but I was happy to keep the plant alive. Looking forward to better results next year, but I will take extra care to keep off the butterflies.

Attacked by caterpillars


Potentially a large attractive plant but being a brassica the plant was a magnet for cabbage white butterflies and the leaves were soon reduced to tatters by masses of caterpillars. Replaced plant with something more suitable.

I bought and planted my Crambe Cordifolia (2 litre pot) from you in November 2012. So far, it is showing very little signs of life. Is this is normal at this time of year?


Hi there A number of plants are late emerging this year due to the weather. Over the next couple of weeks you should start to see the new growth coming through especially now we have some sunshine.


Any reason why myplants are not flowering? Hello. I have some plants that seem to be happy and growing well but aren't flowering- two Fuchsias, a Crambe cordiflora, and a Geranium 'Buxton's blue'. Even those that are flowering are a bit rubbish - a Perovskia 'Blue Spire' and some Verbena bonariensis have produced some flowers but not many. What can I do to improve flowering - is there a particular feed or fertiliser I should use? The soil is dense london clay, but the garden is not shady, but nor is it in full sun. It is quite sheltered. Many thanks, Robert

Hello There, There are a number of reasons why plants don't flower including too much shade, not enough water or nutrients, or pruning at the wrong time of the year. It can also be caused by the plant putting on new root growth instead of focusing its energies on producing flowers. I am not really sure why yours has not produced buds, but you can often give them a bit of a push by feeding with a high potash fertiliser. I hope this helps. Helen Plant Doctor
