Crinum asiaticum germination
P. C. Andrews (Sun, 20 Aug 2006 17:54:35 PDT)
I usually end up harvesting the large asiaticum seeds after they have been
on the ground, baking for a few weeks (not on purpose, just a scheduling
problem). A few seeds will have germinated on their own after a couple of
months. Generally, I bury half to 3/4s of each seed so there is a good bit
of the top showing and then put the pots in partial shade so they probably
get no more than one or two hours of direct sun each day. Success rates are
generally very good, but I also notice that some germinate fairly quickly
and others from the same plant are quite delayed. In general, I think that
partially burying the seeds speeds germination up a bit but I haven't
rigorously tested this.
Have you noticed more rapid germination if you harvest seeds directly from
the pods vs after the pods have split?
I notice that many hymenocallis seeds often act the same for me. I was
loathe to bury them, since they are green and I assume their photosynthesis
apparatus is working, however, I have fully buried seeds from the local
hymenocallis that grows on the dunes and find it speeds germination and I
get a 100% germination rate. I have assumed that its due to reducing
dessication.

Hi Gang,
From time to time I have seeds of tropical-type Crinum. The mother
plants
are garden forms of C. asiaticum or similar plants; the leaves can be red,
green, slim, or wide. Very often the seeds are huge.
The seeds often take a long time to germinate. Typicaly, I put them on top
of good soil in a 2- gallon container and leave them under a porch where
they get rain, bright light, and no frost even though there might be frost
on the grass some feet away. Indoors germination has not sped things up.
Because they are Crinum, I tried a couple of obvious variations (several
months just sitting dry, etc.), but there is no fooling these seeds.
The seeds take their time to germinate, each germinating on its own
schedule. Sometimes these "tropicals" germinate soon after they come out
of
the pod, even while half in the pod and spilling out; sometimes waiting
till
the following spring. I wonder if anyone has the same experience.
Cordially,
Joe
Conroe, TX
Not so hot today, but still no rain.
