More Details

A wonderful courgette with distinctive ribbed stems. It has excellent flavour and texture, never turning watery, even when quite large.

Pick it small and whole, and the flavour is reminiscent of globe artichoke hearts. Its flowers are huge too - ideal for stuffing and dipping into tempura batter.

Do at least two sowings of courgettes, splitting your packets, so that you have fruit to pick for 3-4 months at a stretch. Sow two or three different colours so they look good in the garden and on the plate.

Please note, illustrated packets are being introduced gradually over the coming months, availability may vary.

Sowing, Seeds, Planting Soak seed overnight and sow under cover from late March- April. Push seed, on its side (to prevent it rotting), 2-3cm deep into a 9cm pot of compost. Can be sown direct after last frosts, sow two or three seeds 2.5cm (1in) deep and cover with cloches or jars; leave in place for at least two weeks after seedlings appear. Thin seedlings to leave the strongest one. Indoor-raised seedlings will require potting on into 9cm (3.5in) pots to grow on before planting outside, after the last frosts. Gradually acclimatise seedlings to outside conditions for two weeks by leaving them outside during the day in a bright, sunny spot and bringing them back in, or covering with horticultural fleece in the evening. Prepare the planting area two weeks prior to planting (or sowing). Make a hole about a spade’s depth and width and fill with a mixture of compost or well-rotted manure and soil. Sprinkle a general fertiliser, such as Comfrey Pellets or Organic GroChar Fertiliser, over the soil. Plant one plant in each planting pocket spaced 90cm (2ft 11in) apart. Courgettes also work well in growbags or containers, minimum 45cm (18in) diameter. Allow one plant per container or two per growbag. These will need regular watering as they mature.
Care Tips Water once a week, taking care not to wet the leaves, and feed every fortnight with a high potash liquid fertiliser, such as Organic Tomato Fertiliser with Seaweed, once the first fruits start to swell. Courgettes should be ready to start picking eight weeks from sowing. Powdery mildew can be a problem during hot, dry spells, the only remedy is to keep the soil moist and move plants to a cooler location if possible. Cool weather early in the summer can cause inadequate pollination meaning fruits fail to appear but this is usually a temporary problem and once the weather starts to improve, so will pollination and the plant will correct itself.
Storing Best fresh, but can be stored a few days in the fridge.
Harvesting Late June to October. Start picking as soon as fruits are 7cm long. You can pick the flowers before this.
Cooking Notes 'Romanesco' courgette is beautiful cut in cross-sections, and eaten raw in salads or sauteed simply in a little butter or olive oil.

Reviewed 17th September 2018 by Sharon de jager

My first try at growing vegetables. As a huge courgette eater I bought the Romanesco seeds to try out. Within a few weeks out popped the seedlings and then the fruit started growing. Amazed at how quickly they grew from mere 10cm high into large leaves with lots of fruit and flowers. Delicious to eat. I like to cut them while still small, but my allotment buddy grew them until they were much bigger, however I find if they are left to grow too big they are like marrow and less tasty, so now I've convinced her to cut them whilst still around 12cm. I now know to give them plenty of room to grow, so next time round I shall space them differently. Our first try at growing courgettes was a complete success, in fact today I picked some more. Couldn't be happier with the seeds I bought.

In a cold northern garden this courgette comes up trumps every year. I try several varieties every year and this one always outperforms the others. Masses of delicious courgettes which hold their flavour even as they grow, and lovely flowers
