[*] Great size plants! While I do enjoy growing nepenthes from very small, I'm certainly not going to complain about receiving plants 3-inches across with a half dozen pitchers.
[*] Good eclectic selection of plants for cheap. If you can get over the fact that not every plant will be a Borneo Exotics clone (and you should!), you can get some real interesting stuff!
[*] Can add on plants to an existing order very easily.
[*] Very good packaging. My nepenthes all came pre-potted, with an additional pot on top (filled with sphagnum as insulation) to protect the leaves/pitchers from shipping handling and the cold. Due to USPS issues, my order was in the mail for 8 days, but nearly all the plants are fine 48 hours after unboxing. I noticed that even after 8 days in the mail, they still weren't cold (which is more than could be said for another order that arrived the same day from another shop that forgot to include a heat pack, and had very cold plants).
[*] Very good customer service. Due to the USPS delay (through no fault of Florae), one of the lowland plants was looking a little bad, and took a turn for the worse the day after receiving the package. I sent a picture to their customer service email of the damaged plant - unsure the cause of the damage - and got an email back saying it was definitely cold damage, and giving me credit for the value of the plant. Their customer service was also able to cancel a duplicate order I made in error, and hold my order due to a cold snap a couple weeks ago.
The only real suggestion I have for improvement is to add an "In Stock" checkbox for searching through their available plants! I like to sort "Price Low->High" but usually that results in having to wade through pages of plants that are sold out
In conclusion, definitely give Florae Collaborative a shot, and pick up some of their seed-grown plants or odd crosses!
