Sedum seeds UK: choose the plant before the packet
Updated: 21 October 2026
You have searched sedum seeds and landed on amazon.co.uk packets that all look like ground cover until the second line. One title says Sedum spurium coccineum, another says Sedum acre, one stacks album nicknames, and two only say purple carpet. Prices in this set run from £1.82 to £6.99, which is a real gap for a pinch of fine seed, and it is the wrong gap to settle first. This buying guide matches the plant to the place, then checks whether the listing tells you how to sow and whether anyone in the UK has reviewed it. The full price table is the [sedum seeds comparison](/hub/seeds-and-plants/sedum-seeds).

Three species jobs, not one carpet
Sedum seeds in this UK set are not one plant. The split is Sedum spurium coccineum for a red or pink mat, Sedum acre for yellow moss, and a Sedum album mix only if you can live without one colour. Just Seed sells the first two: 200 spurium seeds at £1.99, and 200 acre seeds at £1.82. Pink against yellow, and partial shade against full sun.
SVI's purple carpet packets, about 50 and 25 seeds at £5.99, never finish the Latin name. The album mix lists Athoum, Murel, babies toes, chubby toes, and coral carpet beside 137+ seeds and never says the split. Write the Latin name you want, then reject any title that lacks it. Gold moss on Pinkdose is still Sedum acre. Colour against height is the spurium or acre comparison.
Just Seed against listings that print a method
Just Seed's spurium and acre listings claim Defra registration 7291 and organic registration AP23164. This file does not include a register lookup, and both pages lack a sowing block. You can pay £1.99 and still need to know that the seed stays on the surface.
TRTO's 160-seed spurium packet at £5.99 and the 240-seed packet at £6.99 say do not cover, press the seed in, 14 to 28 days at 20 to 21 °C, and 25 cm apart. Vision4ever's 180-seed packet at £5.99 says partial shade rather than full sun. Pay £5.99 for those sentences, not for a 5.0 from two reviews. The steps are on how to sow sedum seeds.
Counts, stars, and what a review file can show
Claimed counts run from 25 seeds to 240. A 25-seed packet at £5.99 is a trial pinch, not a bank. Nothing here turns a seed number into grams per square metre.
Just Seed spurium is 3.8 from 106, with titles for fast germination and for seed that did not grow. Just Seed acre is 3.7 from 31, including a title that says not one came up. TRTO's 5.0 from two reviews never shows a failure, because almost nobody has written. Pinkdose is 3.3 from 23 with no excerpts, so those stars are not a UK write-up. Sort by stars and the two-review packet rises. That sort rewards silence.
What ornamental seed rules do not print on the bag
Seed Marketing Regulations 2011, regulation 4, leave ornamental flower seed outside the farm-seed regime. The 1999 ornamental rules still expect satisfactory germination, and none of these listings prints a percentage. A star average is not that percentage. An empty or wrongly described packet is a Consumer Rights Act 2015 complaint, not a refund for every bare tray.
Schedule 9 of the Wildlife and Countryside Act 1981, as checked for this comparison, does not list these garden stonecrops. Sow only on ground you are allowed to plant. A red mat stays on Sedum spurium coccineum. Yellow moss stays on Sedum acre.
Common questions
Are all sedum seeds the same plant?
No. Titles in this amazon.co.uk set split into Sedum spurium coccineum, Sedum acre, a Sedum album mix, and purple carpet lines that never complete the species. Flower fields differ too: pink or red, yellow or gold, and white on one spurium title. The single word sedum makes those £5.99 carpet listings look interchangeable when the plants are not.
Which packet is for a red mat?
Look for Sedum spurium coccineum on the title. Just Seed's colour field says pink. TRTO's bullets say crimson, on packets at £5.99 or £6.99 that also print a sowing method. Purple carpet titles are not a safe stand-in, because they do not finish the Latin name.
Why is Just Seed cheaper than TRTO?
Just Seed is £1.99 for 200 spurium seeds and £1.82 for 200 acre seeds. TRTO asks £5.99 for 160 and £6.99 for 240, with a longer sowing block and only two reviews on each. You are not paying for a proved higher germination rate. You are paying for printed steps and a thinner review file.
Do I need the Latin name on the title?
You do, if you care which plant you grow. Carpet, purple, and gold moss are selling words. Sedum spurium coccineum and Sedum acre name the job. A title that only says purple carpet can still be the wrong colour. The album mix lists nicknames and still does not give a count to each one.
Are these certified farm seeds?
No. Ornamental flower seed sits outside the Seed Marketing Regulations 2011 farm-seed regime. Just Seed prints Defra registration 7291 on the listing. That is a claim on the page, not a register check, and it is not a germination percentage. None of these packets print a figure you could treat as a greenhouse promise.
Can I sow an album mix and get every nickname?
The £5.99 SVI title lists several names beside 137+ seeds and does not say the split. Nothing in the file shows that Athoum, Murel, babies toes, chubby toes, and coral carpet will all come up. Buy it only if an unnamed album blend is what you want.
