I response to message 4 what type of antiviral treatment did you use. Years
ago there was some work done on using heat to kill the virus. There must
be some published work on this. As far as a chemical treatment I have not
heard of any chemical that will kill the virus. Some antifungals will reduce
some of the viral symptoms but do not cure anything. I have done a lot of
propagation work with orchids which can get several non orchid viruses (TMV
for one) and several european growers were trying hot water treatments to
kill the viruse. There was some success but it was found using meristem
tissue (fast growing new growth) did not have high amounts of virus in the
tissue. By removing this tiny growing point and culturing on sterile medium you
can produce virus free plants. I'm sure they are using a related procedure
to mass produce Hippeastrum. My advice would be to isolate any infected
plants and unless they are the last specimen in the world burn the whole
plant. Most plant viruses are transmitted by insects through their sap. If you
handle infected bulbs wear latex gloves or some other barrier. Remember the
virus is all through the plant,leaves,roots and bulb as well as
flowers.Most badly infected plants produce deformed flowers. The flower can be
deformed or have color streaking/blotching/spotting.Oh throw away that dirt you
had your infected plants in cause there could be some viruses lurking there
that can spread to your healthy plants. Also some plant viruses can stand
drying and still be infective. For those not familiar with plant viruses just
do a search online and you will be stunned just how many types there are.
So do yourself a favor and get rid of the virused plants. When cutting
flower stems always use a sharp instrument,like a razorblade dipped in rubbing
alcohol. The alcohol will kill the virus and the blade is reusable.
Remember to keep infected plants separated from healthy ones. Russ H, BS, MS in

I checked the link to make sure it works. It seems to display the blog
in Firefox, which has rearranged some of the headings. If it is viewed
in Internet Explorer it is OK.

Dear Dennis Thanks for reminding me. We have some LA iris in bloom
both hybrids and the very late species I brevicaulis. Also a few I.
psuedata. This name may be new to some of you. It is a hybrid of I pseudacorus x
I ensata. Modern hybrids are far superior to older attempts and have large
flowers in a range of colors and patterns. And they are sterile so unlike
the pseudacorus parent do not seed about wildly. Recommended for pond or
well watered garden spot.

I don't think there are any pix on the PBS wiki yet.

Some time a ago I posted about an anti-mosaic virus treatment for
hippeastrum bulbs. I think the method is OK as a last resort. It
certainly eliminated the of mosaic virus marking on the survivors, but
I can't be certain it is really gone. The bulbs I treated were
identified as H. equestre red, H equestre pink and two different H
reticulatum striatafolium, all from Thailand. The 'equestre did the
best with substantial leaf growth and decent root growth. The
reticulatum bulbs keep aborting their leaves but had good root growth.
I decided to dispose of the virused bulbs to protect all my others.

On the Pacific Northwest coast, Columbia lily has beaten out Martagon
lilies to flower first. Buds are out but mostly green on other lilies.
Late Pacific Coast iris are flowering; these are I. tenax selections and
some hybrids (tenax x innominata), and dwarf I. douglasiana seedlings. Also
one clump of I. hartwegii australis continues to toss out a flower every
week or so.
Colchicum foliage is dying down, so I am digging out bulbs to make room
for more iris plants.
Lobelia tupa has flower shoots with colored buds, though I don't expect
flowers for some weeks to come.
Ornithogalums are flowering, as is Sisyrinchium californicum, S.
idahoense, and several selections with blue flowers.
Seeds are ripening on several Erythroniums??and I may be able to send
seeds to the exchange in several weeks.

Cheers,
Kathleen

Came as a surprise yesterday morning. Leaves died back and I had it ready
to go into the basement for the summer rest.

Flower lasts only a day.
