When I spent 9 years in Florida up until 2018, orchids in stores were quite common. It was Florida after all!
Home Depot, Trader Joe's, and Lowes always had plants. Home Depot had the best selection or variety should I say. Small and medium Cattleyas, a few Vandas, several Oncidiums were around as well. Phalaenopsis were the most common orchid available but they were the most beat up due to the non orchid public just having to pick them up to look at them. Spikes and leaves were often damaged and broken.
Here in Michigan in Lowes it is Phalaenopsis, both standards and little minis. Very few however during the months of December through February. The weather is just to cold to transport them home. I have seen "the little bag babies", only once this past summer in Lowes, but those are rarely seen. Trader Joes up here carries Phalaenopsis mostly and Oncidiums during the nice weather.
But in a short period of time, I have 7 shoes coming up in rather ice cold weather. Grand Rapids in the end of January, Cleveland Ohio in early February, Lansing in late February, Akron in early March, Ann Arbor in mid March and the Michigan Show in early April. The last show with the best weather will be Strongville Ohio in late April.
If anyone needs more information just let me know. I will be judging at all 7.
