Best petunia seeds in this amazon.co.uk set

Updated: 21 October 2026

You want a packet that will still make sense when the flowers open, not a laboratory winner. There is no trial bed behind these twelve listings. Best here means a named variety you can reorder, a price in pounds on amazon.co.uk, and review text that does not contradict the title. The [Petunia seeds comparison](/hub/herb-seeds/petunia-seeds) is the grid. This page says who each group is for, and who should skip it. Peter F. used the listings and UK review themes in this set, plus public growing guides. He did not germinate the packets. A qualifying purchase can earn a commission at no extra cost to you.

Our top picks

What best can mean here

The criterion is identity first. A packet that names the series, the colour, and the seed form beats a title that only offers a count and a basket photo. In this set that identifiable buy is Just Seed Double Pirouette, two listings at about £2.25 for 30 pelleted seeds. Just Seed's own page calls the series compact, with flowers about 10–13 cm, and allows about two to three weeks for germination. A 3.9-star line is not proof of the right flower. The petunia seeds buying guide keeps the general checks.

Named pelleted packets

Double Pirouette Blue, B00OIOYX16, is about £2.25, part PETPIRB001, 3.9 from 77 reviews. DEFRA registered 7291 and organic registration AP23164 are registration lines, not a germination percentage. UK comments include good germination, a replacement after an empty packet, and a later batch that did not germinate. Buy it for a named blue double. Skip it when the basket must spill. Double Pirouette Red and White, B00OIOYRGC, is the same price and 30 pellets, part PETPIRRW001, at 3.7 from 121 reviews. That larger file is why it is the best value line beside the blue top pick. One UK review says the flowers were purple, not red. Skip it when red and white is non-negotiable, or when you needed a trailer.

Listings that say hanging

SVI, B084VK2Y35, is about £5.99 for 100 pieces, 2.3 from seven reviews. UK reviews say the plants were not blue and not trailing, or that the flowers were pink rather than a pictured Night Sky type. The usage field says indoor. Nika's balcony mix, B0DRLFW3CG, is about £2.99, 3.9 from 20 reviews. The title says 2,500 and the item count says 300. One UK review says the plants were upright. Damavand, B0GMY8N997, is about £3.50 for nana compacta mixed, 2.0 from two reviews, and one review says it was not trailing. Ultrey, B07PVGRLJC, is about £5.99 for 200 seeds, 3.6 from 180 reviews. The bullet says hanging or standing. Repeated UK reports describe plants that were not trailing, odd colours, and weeds or poppies.

Unnamed packs with no star line

Six listings have no customer-review line. DSRERYHT, B0HDH8FFPR, is about £4.78, with 25,000 in the title, a unit count of 1, and colour letter I. UIOYEWRG colour B, A, and Mix S (B0H7SB53VK, B0H7S3KP8X, B0H7S4PM3H) are about £7.75, trailing in the title, with a hardy-perennial claim and no seed count. Colour D and colour O (B0H9DBWD6B, B0H9D854ZN) are about £6.10, with 25,000 in the title and a unit count of 1. Do not fill that gap with the 3.9 from a different ASIN. The named pellets remain the packet to sow when you still have a warm windowsill.

Common questions

Which packet in this set actually names the variety?
Just Seed Double Pirouette Blue (B00OIOYX16) and Double Pirouette Red and White (B00OIOYRGC). Each states 30 pelleted seeds, a part number, and about £2.25. Damavand names the class nana compacta, which is a habit group rather than a series such as Pirouette. The other listings use a colour letter, blue 2, or no name. A basket photo is not a variety.
Who should buy the £2.25 Just Seed pellets, and who should skip them?
Buy them when you want a named compact double and you can cope with mixed germination reviews, including empty packets. Blue is the stronger colour match in this file. Red and white has more reviews and one report of purple flowers. Skip both when you need a long trailer. The brand describes Pirouette as compact, with flowers about 10–13 cm, not as a cascading basket plant.
Are the £5.99 hanging bags a better basket bet?
Not on the reviews in this file. SVI at about £5.99 has seven reviews and reports of plants that were not blue and not trailing. Ultrey at about £5.99 has 180 reviews and repeated reports of upright plants, odd colours, and weeds or poppies. A hanging word on the title did not match what those buyers described. A named compact packet is clearer, though it is the wrong habit if spill is the whole point.
Is a 2,500-seed mix at £2.99 good value?
Only if you accept an unnamed mix and a count the page does not agree. Nika's title says 2,500 and the item field says 300, at 3.9 from 20 reviews. One buyer said the plants were upright. That is a cheap experiment, not a better buy than 30 named pellets at about £2.25. No germination percentage is given, so the large count is not a yield.
Why are some £6 to £8 packets a worse identity bet?
UIOYEWRG colour codes at about £6.10 and £7.75 have no star line, no variety, and often no seed count, or a 25,000 title against a unit count of 1. You pay more than £2.25 and cannot reorder a named flower. Hardy perennial and all regions are not an RHS code. Leave them when the basket depends on a known habit. They are not a premium form of the Just Seed packet.
Can I treat a 3.9-star score as proof of the right flower?
No. Just Seed Blue and the Nika mix are both 3.9 in this file, and they are not the same product. Stars mix germination, colour, and whether the parcel arrived. Read the comments. A purple-not-red note, or an upright plant from a trailing title, matters more than the first digit. Six other listings have no star line at all.
What if I need a basket in flower and it is already May?
Sow seed only if you still have weeks under cover and you can wait. A packet started in late May will not fill a basket that must look finished now. Buy plants for this season and keep seed for next spring. Petunias are frost tender, so even plugs wait until frost has passed where you live. This set does not include a plug price.
