The AOS Montreal Judging Centre has begun a conservation project of Catasetum (Ctsm.) maculatum and Ctsm. tabulare orchids. There is an informal blooming challenge to see who can bloom either of the Ctsm. maculatum or Ctsm. tabulare first.

The Ctsm. maculatum is from the wet forests of Mexico and the Ctsm. tabulare is from the wet forests of Columbia. 

The Ctsm. tabulare was chosen by Pat Vuurman and Rob Vanderheyden for our society to grow as it appears that it does not require a dry period. Where it grows in the Chocó area of Columbia, there is no dry period. That area is said to receive up to 8,000 mm. of rain per year. Growing tabulare will not require water to be withheld starting in January until new growth appears like most others in this tribe, which will be easier for us.

They like high light, warm temperatures, and lots of water and fertilizer during their active growing period.  More information is available at http://orchidspecies.com/catatabulare.htm.

1. There are 45 seedlings available for this challenge with a limit of one seedling per OSRBG member per household (unless there are surplus plants when all requests will be filled). People who are not members of our society will be welcome to buy plants if there is a surplus. The deadline for requesting a seedling will be November 13, 2022. 
2. The plants are priced at $10 per seedling.
3. Reservations can be made by contacting Rob Vanderheyden on a first come – first served basis at orchidataOSRBG@gmail.com. Plants are to be picked up when members attend the November 20, 2022 OSRBG meeting at the RBG unless other arrangements are made.
4. Proceeds, after the cost of the seedlings, pots and moss is deducted, will be donated for conservation projects that the Orchid Conservation Alliance funds. 

 Presently, the seedlings are potted in 2″plastic posts in sphagnum moss which seems to be the preferred medium for growing Catasetinae family orchids. At the moment, they are growing in front of a patio door that faces west.
