Best broccoli seeds for a named job

Updated: 21 October 2026

Best broccoli seeds, in this set, means the listing that matches one job and whose reviews you can place. A 4.6 from 23 pre-harvest UK notes is not the same evidence as a 4.6 from 3,298 reviews written outside Britain. The [broccoli seeds comparison](/hub/herb-seeds/broccoli-seeds) holds every ASIN. If the crops are still mixed, start with the [broccoli seeds buying guide](/hub/herb-seeds/broccoli-seeds/sub/broccoli-seeds-buying-guide). The top pick is a jar. Best value is an autumn head.

Our top picks

Best if you want purple spears

Early Purple is the clearer spear packet: 500 seeds at about £4.09, sow March to May, harvest February to May, 60 cm apart. The amazon.co.uk line is 4.6 from 23. Both UK texts praise plants or spring greens, and neither describes a finished February cut, so you are trusting the instructions more than a harvest diary. Choose it for named purple sprouting with months and spacing printed. Skip it if the bed must be empty by autumn, or if you wanted a jar this week. Claret F1 is 25 seeds at about £1.95, sold as a Kings Seeds pack, with 5.0 from one rating and no review text. Saved F1 seed will not come true. Buy it only if you already grow Claret. The head-or-spear split is on calabrese vs sprouting broccoli.

Best if you want a green head

Mr Fothergill's Green Calabrese, model 25029, is the best value heading packet: about £2.39 for 250 stated seeds, sow March to May, harvest September to November. One of two UK reviews says every seed sown germinated. The other is a thank-you. There is no depth on the listing, so this is not a top pick on evidence. It is the sensible price next to Covina at about £3.49 for about 50 seeds, which has a later window and no reviews, and next to Batlle at about £1.40. Batlle's 4.1 from 527 is not written in Britain, and one buyer reported about 300 seeds against a 1,500-piece title. Skip Green Calabrese for winter spears. Skip Batlle if you need UK cropping notes. Raab and Kailan Kichi are different crops, with a disputed kai lan count of 300 against 150.

Best if you want jar sprouts

Natures Root's two 250 g bags at about £20.98 are the top pick for a jar. The line is 4.5 from 1,640, with a large UK sample. People commonly describe a full jar in about four to six days from a tablespoon, an overnight soak, and two rinses a day. A minority mention mould, a smell, or up to half the seed left unsprouted. Organic is on the title, with no control-body mark in the file. The 2 × 1 kg listing at about £47.98 repeats the same reviews and is cheaper per gram on the stated weights. Rainbow Waltham 29 at about £32.25 for 454 g costs more per gram, and its 4.6 from 3,298 is not a UK sample here. The cooking rule is on the sprouting at home page.

Listings that are not a best pick yet

Covina has a wide sowing window and no star line, so it is not a top pick on reviews. It matters if you must sow after May and you accept about 50 seeds. Raab has no buyers' notes here. The Unwins collection at about £3.39 is 5.0 from one rating and does not name its varieties. Unwins microgreens at about £2.08 have one UK review text, the word taste. A lone 5.0 is a click, not a trial.

Common questions

Which packet is the best purple sprouting buy here?
Early Purple, about £4.09 for 500 seeds, prints March to May, a February to May cut, and 60 cm. The 4.6 from 23 is real, and both UK reviews stop before harvest. Claret F1 is only if you already grow that variety.
Which calabrese packet has a UK germination comment?
Green Calabrese. One UK reviewer says every seed they sowed germinated, inside a 4.2 from 19. Covina has no reviews. Batlle's germination praise sits in non-UK texts, beside a report that about 300 seeds arrived instead of 1,500.
Is the cheapest packet the best value?
No. Batlle at about £1.40 has a disputed count and reviews that are not British. Green Calabrese at about £2.39 for 250 named seeds, with a printed season, is the better heading price.
Which sprouting bag has UK reviews?
Natures Root. The 4.5 from 1,640 and the UK jar notes sit on the 250 g pack of two, and the 1 kg pack shows the same run. Rainbow's written reviews in this file are American and Mexican.
Should I trust a 5.0 from one rating?
Not as a crop result. Claret F1 and the Unwins collection are each 5.0 from one rating with no text. That does not outrank Early Purple's 23 ratings or Natures Root's UK jar sample.
Why is Covina not a top pick on stars?
There is no star line and no review text. Covina can still suit a June sowing and a domed head, at about £3.49 for about 50 seeds. Stars cannot promote a listing that has none.
Is the 1 kg bag better than the 250 g bag?
It is cheaper per gram on the stated weights, and a worse first buy. You pay about £47.98, a failed jar wastes more seed, and the reviews are the same run as the £20.98 pack.
