TOW Tuberous Pelargonium - Part 2

Dear David,
Thanks for the wonderful introduction to tuberous Pelargonium which was a
really good read. Are there other members of this group growing these
plants? Please speak up and tell us what you are growing and what your
experience has been.
I heard Michael Vassar speak twice and show pictures of his Oxalis and
Pelargonium collections. It was clear that he was crazy about both. I'm not
sure photographs do justice to the Pelargoniums and that may be the reason
they are not more popular.
Dirk Wallace sent me seed of my first tuberous one, Pelargonium
incrassatum. I didn't ask for the seed (it was a nice thoughtful bonus) and
wasn't planning to grow Pelargonium, but of course I started the seed. It
germinated well but I lost a lot of those first plants so David's remarks
about the first year being tricky was appreciated. I loved the foliage, but
when it finally bloomed I found it dazzling. O.K., it probably is one of
the most spectacular, but after that I thought I'd like to grow some more.
When we saw them in South Africa I was even more intrigued because they are
really so unusual. I'm not sure any of our slides did them justice although
there was one I need to look for that was rather spectacular (can't
remember if it was tuberous.)
I haven't done as well growing the others I have tried. Partly I've never
been sure about when to water. And I didn't know on transplanting how deep
to plant them so David's remarks about cultivation were helpful too. I
assumed they wouldn't like my wet winters and humidity even if I sheltered
them, but if David can grow them in a greenhouse maybe I could as well. My
P. incrassatum is in my outside covered bulb structure (open sides) and is
usually looks like it would appreciate more light.
My friend Andrew Wilson who lives in San Diego sent me pieces of two of his
plants a year ago in the spring. One was a cutting and the other a piece of
stem. Both looked long gone from my perspective. I wrote him back asking if
he really thought anything could possibly grow from that dead looking stick
and wilted looking foliage. Well, perhaps I was a bit more polite. He told
me to be patient and indeed they both rooted and came into growth. One was
P. fulgens which has bright red flowers. It remained green all summer and
then bloomed late summer-fall and then started looking a bit weary and I
just wasn't sure what to do with it. I finally cut off one of those stems
that had dried up and the plant put out new lush foliage. I'd be curious if
some of these could be grown as evergreen plants. Do they need to lose
their leaves or just do it because there is no rainfall?
The other one he sent me was P. echinatum which I also grew from Silverhill
seeds. Andrew's plants have bloomed twice (blooming now) and are really
pretty. I'll try to get a picture on the wiki. I had a hard time getting my
seedlings from Silverhill to start growing again after they went dormant,
but they still look alive.
The same was true for P. magentum seedlings (is this a tuberous one?) We
saw that one in South Africa and it was a beauty. I also have some
seedlings of P. barkeri from Silverhill Seeds last year that have made a
tuber and one even started to bloom less than a year from seed, but kind of
gave up quickly.
I agree with David that one of the interesting things about these plants
are the leaves. The flowers are a bonus and the tuber often very
fascinating as well. When I looked through the information on the wiki I
was surprised to see the different times of year they bloom. I assumed they
would all be spring flowering.
