I know Epi, Holiday Cactus and Brug cuttings can be send in Bubble Envelopes to save on postage, are there others?

What Plants/Cuttings Can Be Send In Bubble Envelope??
Lily bulblets, euonymus cuttings, dormant rose cuttings, dormant hydrangrea cuttings. Anything which does not get hurt by a slight squeeze. If you have tender stems, leaves, or root materials which can get damaged if squeezed a bit then avoid same (e.g. caladium would probably be ok if no sprouts, but once they sprout it is a no-no.
Just one comment. remember that usps will consider your bubble envelope a "package" if it is more than 1/4" thickness. So if you put a cactus cutting into an envelope, and it is now 1/2" wide... you will be billed as per package, and then you could just as well have sent it in a priority mail box anyway....
I once received about ten feet of Wisteria vine in a large padded envelope. It was wrapped like a wreath. LOL Hey, it came out in perfect shape and blooms twice a year for me.
