Grow Kits That Actually Work: Rainbow Veg vs Unkillable Plant

Compare the Radical Rainbow Veg and Unkillable Plant grow kits: what the seed packs promise, what they don't, and which low-maintenance indoor grow kit gift fits your giftee.
Two seed kits, one honest starting point
The Radical Rainbow Veg Grow Kit and the Grow It Unkillable Plant Grow Kit both promise the fun of growing something from seed, but they set very different expectations. One sells colourful edibles; the other leans on the idea of a plant tough enough to survive neglect. Before you pick, it helps to know what each kit actually contains and what the packaging itself says about the seed inside.
Neither kit is a guaranteed harvest or a guaranteed houseplant. Both are novelty gifts with real seed, and both carry the same blunt warning: the seed can die before or after germination, so plant it as soon as possible. That single disclaimer is the most important thing to compare, because it reframes the whole purchase.
What each kit promises vs what the packaging admits
- Radical Rainbow Veg Grow Kit: Marketed as a way to grow 'wonderful, brightly coloured veg which you can really eat.' The pack contains real plant seed of UK origin, and the disclaimer notes that seed may be substituted with alternatives depending on availability.
- Unkillable Plant Grow Kit: Marketed around a 'super tough living stone Plant' that is 'proven to survive even the most irresponsible plant parents.' It also contains real UK-origin seed and carries the same seed-death and substitution disclaimers.
- Shared limitation: Both kits state that images are for illustrative purposes only and that each is a novelty gift. Neither supplies step-by-step growing instructions in the catalog evidence, so the pack itself is the reference you keep.
Radical Rainbow Veg: the edible angle
- Gift Republic Radical Rainbow Veg Grow Kit: Grow wonderful, brightly coloured veg which you can really eat! This is the clearest functional difference: the Rainbow Veg kit is positioned as a food-growing gift, not just a decorative plant.

Gift Republic Radical Rainbow Veg Grow Kit - Gift Republic Radical Rainbow Veg Grow Kit: This pack contains real plant seed, origin UK. Confirms the kit is a genuine seed-growing product, while the UK origin is a detail some gift buyers care about.
- Gift Republic Radical Rainbow Veg Grow Kit: The seed can die before or after germination. Please plant your seed as soon as possible. Sets a realistic expectation: the kit is perishable and timing matters, so it is a poor choice for a gift that will sit in a drawer for months.
Unkillable Plant: the low-maintenance claim
- Gift Republic Grow It Unkillable Plant Grow Kit: Well good luck killing this super tough living stone Plant, proven to survive even the most irresponsible plant parents! The kit's entire appeal is low maintenance, which makes it the stronger match for a recipient who wants greenery without a care routine.

Gift Republic Grow It Unkillable Plant Grow Kit - Gift Republic Grow It Unkillable Plant Grow Kit: This pack contains real plant seed, origin UK. Despite the 'unkillable' framing, this is still a seed kit that needs planting, not a ready-grown plant.
- Gift Republic Grow It Unkillable Plant Grow Kit: The seed can die before or after germination. Please plant your seed as soon as possible. The same perishability warning applies, so the 'unkillable' label describes the mature plant's reputation, not a guarantee for the seed.
The trade-off: novelty versus a reliable result
If you want a gift that delivers a predictable outcome, neither kit is the safe pick. Both are explicitly novelty gifts, and the supplier accepts no liability for non-performance of the seed or the coir discs and pots. That is not a flaw unique to these two products; it is the nature of seed-based gifts.
What changes between them is the story. Rainbow Veg offers the novelty of eating something you grew, with the caveat that varieties may be substituted. Unkillable Plant offers the comfort of a plant marketed as nearly indestructible, with the caveat that you are still starting from seed. Choose the story that fits your recipient, not the one that sounds most foolproof.
Which grow kit fits your giftee
- Choose Radical Rainbow Veg if: The recipient enjoys kitchen gardening or is curious about growing something edible, and you can hand it over close to planting time. The colourful veg angle is the main draw.
- Choose Unkillable Plant if: The recipient likes the idea of a low-maintenance houseplant and has a sense of humour about past plant failures. The living stone framing sets a different expectation from a vegetable patch.
- Skip both if: You need a guaranteed living plant, a specific plant variety, or a gift that can wait indefinitely before planting. The seed-death disclaimer and possible substitution make these kits a poor fit for those needs.
What the catalog does not tell you
Neither record supplies a growing guide, a germination time, a light or watering schedule, or a list of exact seed varieties. The Rainbow Veg listing notes that substitutions may occur, so the exact colours you get are not fixed. The Unkillable Plant listing names a living stone plant but does not detail care steps.
That absence is a decision limitation, not proof that the packs contain no instructions. Both listings advise retaining the packaging for future reference, which suggests the pack itself is where the practical detail lives. If you need certainty before buying, treat these as novelty gifts first and growing projects second.
