While I have never ordered (yet), I've seen that lots of people like them. The only negative I've read is that the plants are smaller. But they're healthy.

Yes, Violet Barn is a reputable company. The plants are very small, starter size. They are an affordable way to start a collection

The plants are very small, but healthy, and personally I like to watch them grow! These are a few different Hoya's I recently bought from the violet barn,

Small, healthy plants that generally grow like weeds. Of course, growth rates differ and all. Great customer service and they often have a few that are harder to find, and less expensive than Gardinos if you are looking to expand your collection on a budget. For anywere from a few to $10 more depending on type you can get a much much bigger plant of similar health from Gardinos. Depends on what you are looking for, how much you have to spend, and how patient you are. :)

I bought a H. pubicalyx Chimera (Royal Hawaiian Purple) from Violet Barn. I had bought violets from them before anyway, so I trusted them. The plants are very small, but mine really has grown a lot in the year I've had it. You may want to get a violet too! ;)
