I've always bought orchids at flower shops. Then about two years ago, I found out some other places also sell orchids.
For the past two years, the price hasn't changed in any of the places I go to look (and sometime buy).
Food Emporium- phals in 4-5 inch pots at $39
Smaller ones at $19
Whole Foods- phals in 4 inch pots at 19
Home Depot- phals in 4 inch pots at 14-19
Trader Joe's-phals in 4-5inch pots at 23
mini phals at 6-10
Home Depot had really quality phals (white, white with red lips and pink most of the time, every so often green, yellow, purple) when I first shopped there two years ago. Now they offer more varieties, but the quality is just aweful I don't ever buy from them although I've been watching for any change.
Whole Foods- quality is usually good. Occasionally quality is significantly down. the selection has increased, which is nice!
Trader Joes- nice mix with surprised every now and then. Quality is so so. I really have to search for decent looking plants.
Food Emporium- same as Whole Foods, except their price is the worst.
Local farmer's market- there are three vendors that carry orchids. One is specifically an orchid store coming all the way from southern NJ. Their phal hybrids seem to be their own hybrid. great flowers but the plant size is also large, so I don't buy from them.
The other two places sell orchids along with a bunch of different plants. One of them carry basically the same phals as Home Depot does, so I skip them.
The other place is where I usually pick up phals.
Good selection, all have name tag, price is $10 for minis and 25 for a regular phal with one spike and 28 for two spikes. (this is an increase from last year when they sold all phals for just 20). Still not bad compared to 35-45 at flower distric or 50 to 100 at neighborhood fancy flower shops.
I also go to a Chinese lady a bit out of my neighborhood where she sells phals for 20. Well, she sells any orchids for 20, except for nobile dendrobium hybrid which go for 25.
I never get bored in this city!!!
