The local nursery should have them, try calling them. Also if you need a bunch of them try ebay, put in orchid pot in search..lot of folks are trying to get rid of inventory. Also there are some orchid socieites(search for phoenix orchid society), once happen to go to their exhibit at some park in downtown, they had lot of fancy orchids, and supplies.

With that height and form and late season bloom, I'd guess they were a type of orienpet hybrids, sometimes sold as "tree lilies". But there are dozens of very similar looking cultivars so can't get very specific as to ID. Most of the better lily specialty nurseries carry them: B&D Lilies, The Lily Pad, The Lily Flower Store, Brent and Becky's, etc.

Do you mean the actual storage boxes or the cubes? The boxes are available at places like the Container Store or Storables and often at office supply stores and places like Home Goods, but with less of a selection. Cube storage systems are available just about anywhere!!

Quinces are typically a cooking fruit, and the majority of American can't be bothered to prepare time consuming things from basic natural sources anymore, so quinces have fallen out of popularity. In the old days, before they had powdered pectin, quinces were used to make jams. It only takes a little bit of quince to act as a thickener. They were also used in apple pies. Maybe 1 part quince to 3 parts apple. They could best be described as being similar to apple and pear, but with a unique aromatic flavor that apple and pear do not have. You might be able to find quinces in a high end supermarket, but typically only seen during the Fall season, soon after the fruits have been harvested. Although the fruits can last a long time in storage if properly handled. Depending on where you live, you might also check out health food stores. Especially medium to larger sized health food stores which are independently owned, not corporate chains.
