The only time you have to be concerned buying orchids is the winter time Abigail. They do not like temperatures around freezing. Exposure to outside temperatures, say 36 degrees as an example, with a breeze blowing creating a windchill can cause a great deal of damage to an orchid. It could only take a few minutes for that to happen. Otherwise you will have no trouble.
Just getting an orchid from a warm place, into a cold parked car could prove fatal. The fairly thin structure of an orchid flower like an Oncidium or Phalaenopsis can freeze easily. Plant tissue turns dark, soft, from a mushy green for a leaf, to black in a matter of hours.
Obviously I am safe at home!! I miss them too much already.
That's Nick with his better half Marta!
