  [Aroid-l] arum question

Hello, Tony!

Maybe you are correct about the envy. But we must all remember that no
matter which aroids we enjoy, we are all "brothers in arums".

Yes, I have had that happen. It does not happen every year, but it does
happen. I have a bed of A. italicum on the north side of my home, right
under the condensation drip of my air conditioner. Additional shade is
provided by a 1.5 meter Tasmanian tree fern and lots of sword fern. Add to
that a top dressing of babies tears, and this one bed stays fairy cool and
moist. As a result, a small fraction of plants do not go dormant during the
summer about every three years or so. The plants that did not go dormant in
the summer always do in the autumn, and start poking up again mid winter. I
tried to recreate these conditions as an experiment and the tubers rotted.

As a side issue, I have had an A. palestinum ecotype from Mt. Carmel break
dormancy in July and August rather than December/January, but again not
every year. Also, I think that CJ Addington has had A. pictum bloom in the
spring rather than in the fall.

In that same vein, I have one Pinellia pedatisecta starting to come up. It
and all its buddies just went dormant a month and a half ago.
