Loved by our happy gardeners.

Honestly… best bulbs I’ve bought online so far. They arrived looking healthy (firm, not dried out) and everything was labeled clearly. I planted them the same weekend and I’m shocked how fast they started growing. My garden finally looks “full” instead of random patches 😂

I bought for my mom as a gift and ended up ordering for myself too. The instructions were actually useful (not just generic). We planted them in pots + border and both worked. Really satisfying to see them pop up after a couple weeks. 10/10 would recommend if you want “easy wins” in the garden.

Super smooth order, no stress. The bulbs arrived dry and clean (no mold or weird smell). Planted them and basically forgot about them… and then suddenly my garden had colour everywhere. I’m not a pro gardener at all so this felt like cheating 😅

First time ordering bulbs online and first time planting them… and I’m not gonna lie, I found it kind of scary. I kept thinking “what if I mess it up and nothing grows?” The bulbs looked good though and most of them did really well. One variety bloomed later than I expected, but overall I’m happy and I’ll order again (now that I’m less nervous).

Very happy overall, but I had to be a bit patient. Some bulbs took longer to show than I expected, so at first I thought I did something wrong. In the end they all came up and looked great. Next time I’ll just trust the process more.

I don’t usually order plants online, but this was a great experience. The bulbs arrived firm and healthy, and the planting guide made it very easy. Seeing the first blooms appear was genuinely satisfying.

These are the kind of bulbs you open and immediately think “okay, this is quality.” Everything was packed well and nothing was crushed. I planted according to the guide and nearly everything came up. The blooms were strong and didn’t flop over like some cheap ones do. Really impressed.

I was worried because last year I had a bad experience with bulbs that never grew. So I was skeptical. But Blom delivered. The bulbs looked fresh and not dried out. I planted them in late spring and I got a ton of flowers. It actually made me enjoy gardening again instead of feeling annoyed at wasted money.

I didn’t expect them to look this good in real life. The bulbs were bigger/stronger than the ones I got last year from another shop (those were kinda sad). With Blom everything came up and the flowers matched the photos really well. Also delivery was quick and the packing was neat.

Planted these martagon lilies in a mixed border and they came back strong. Beautiful curled blooms and a really natural wild look. Exactly what I wanted.

Perfect if you want a pretty garden without being “that” gardening person. I’m busy and I don’t want complicated. I planted, watered a bit, and they basically did their thing. The result looked like I knew what I was doing. Friends asked where I got them.
