Real gardens; Planting Iris rhizomes
Robt R Pries (Thu, 24 Jan 2008 12:28:38 PST)

Marguerite; I have heard various arguments for how to
plant Iris rhizomes in different climates. I have an
almost fool proof answer. Look at the plants you have
that have been in place for a year or two. The Iris
will push itself deeper or crawl further out of the
ground according to its own sense of conditions. Your
established plants can tell you exactly where a new
plant should go. Most rhizomatous Irises have the top
of the rhizome exposed to some degree. I like to
consult with my plants before I make decisions.

This is definitely an interesting topic. It
fits in well with the
PBS original mission of 'using bulbs in the garden.'
Sometimes our
topics are about collections or their scientific
basis, and occasionally
about our gardens. I enjoy both kinds of topics.

I do agree with Robert that our collections and
our gardens are
different beasts. I am on a mission this year to
get my garden back
into shape after several years of neglect. It is a
challenging task,
but an enjoyable one. I have ordered some old roses
(which I mix into
my cottage garden area or my shrub border) and many
new bulbs. In fall
I always add new daffodils to the hillside where I
live. On a previous
property, I once crawled under the chaparral and
planted some near a
seasonal spring. That did make sense at the time,
as both I and my
daughters had a secret sitting place where they
could be viewed when in
bloom. (I no longer crawl under chaparral, but
sometimes miss the days
I could!) I've always wondered what future owners
thought when they
found them.

I would like to hear more about which bulbs can
be moved outside in
my 'colder than normal California' zone. As I repot
my rainlilies this
year, I am putting a few out into my raised bed,
starting with
Habranthus. Those that have gone out in previous
years have done well
and always show surprise blooms when in Aug-Sept.
when everything else
is becoming dry and sere.
Most bulbs (and many other plants) get planted
into gopher baskets,
as that is a big problem on uncleared land, which
surrounds my living
area. Other bulbs have been chancy. Lycoris
radiata has divided into
smaller plants, did not bloom last year or the
squirrels ate the blooms
before I saw them. They are now in cages to protect
from both gophers
and squirrels. The need to put wire around plants
makes them less
attractive, although if I have to put wire above the
soil, I use the
green coated stuff. That helps, at least from a
distance.
Ipheon is a lovely little bulb that gets spread
around the garden
areas. Either I do it when I plant annuals nearby,
or the gophers carry
them away and spit them out somewhere else. They
are a sweet little
surprise when they bloom in an unexpected place.
Irises are also favorites. I have planted many
bearded Irises over
the years and love their scent and colors. The
squirrels have really
abused them the past three seasons, but I see (or
rather hear) signs
that coyotes are back and doing their job with those
nasty
garden-eaters! I was really surprised to find one
eating an Iris bud
after the fire three years ago; there was no food
for them in their
normal dining areas. They had never messed with the
Irises before that.
One question I have always had is whether to plant
them with the
rhizome showing above the soil line or not. I have
read both pieces of
advice in reputable sources. I have tried both
ways and can't really
determine a difference. I love the miniature Iris
reticulata and all
of its cultivars. I see one is available at Brent
and Becky's Bulbs
called 'Marguerite.' It is definitely on my next
order list.

And Calochortus is another favorite. I don't try to
plant it in the
garden much, although I am starting a dry-sandy bed
for Penstemons and
may get a few in there. C. concolor and C.
splendens grow as natives
all along my access road. Spring can be lovely here
when the
wildflowers bloom. We actually have had 7 inches
of rain so far this
season. After a many-year drought, this may be a
sign of a good
wildflower year. I am definitely hoping so!
