The Chelsea Flower Show 2012 (Part 2)The Chelsea Flower Show 2012 (Part 2)
September 1, 2012

The Chelsea Flower Show is an eagerly awaited event after our long winter. It is the first time everyone gets together and can see the new plants as well as creations of sculptors and artists. A lot of gardeners use it as a social event, or to order sensational plants for the coming season in whatever variety interests them. On the final day a lot of the plants are sold off and London is awash with a sea of plants. It is a truly amazing sight!

Careful when reaching in to harvest seeds from a female plant blossom, as some people can (unknowingly) have an allergic reaction to the blossom. Always wear long sleeves and gloves to avoid an itchy, burning, sensation along your arms. It's very similar to what you experience after laying fiberglass insulation!

Blondmyk On October 24, 2014 Potted up
Planted three of the four pups today in pots that I deemed of appropriately small size for the pups. They only require a little space to grow and do not appreciate larger pots. They seem to have dried successfully and I'm hoping that I haven't let them dry for too long. Some of them look like expanded pine cones. It should be interesting to see how they do. I used standard Miracle Gro potting soil with an over abundance of perlite added additionally. Next transplant they will be introduced to the native sandy soil.
Blondmyk On October 1, 2014 Obtained plant
Obtained 4 pups from an aged Mother plant at 1134 Central st in front parking area. A week later I discovered a much larger 8" pup there as well. All of these are curing on the back porch...cleaned and allowing the scabs to dry over.
