Availability is based on a first come, first served system. When you receive your seeds/bulbs you will find, included with them, a statement of how much money you owe (usually $2.00 ? $5.00 per share of seeds or bulbs + postage and packaging charges), and instructions about how to pay. PAYMENT IS DUE AS SOON AS YOU RECEIVE YOUR PACKAGE.

? ? Many of you are subscribers to this pbs elist which is free, but are not members of the Pacific Bulb Society which has a yearly membership charge.

? ? ? ? ? ? I WILL REPLY TO YOU WITHIN 24 HRS OF MY RECEIPT OF YOUR ORDER.
IF YOU DO NOT HEAR FROM ME, TRY AGAIN !!

TUBERS - in very limited supply:

1. Sinningia cardinalis "Innocent"
2. Sinningia cardinalis
3. Sinningia "Peridots Sand Pebbles"

"The cardinalis were approaching their natural dormancy.? They should be only lightly watered until growth resumes, which could take a couple months.? The "Peridots Sand Pebbles" were in rampant growth & will probably grow vigorously immediately once repotted.? To my knowledge this hybrid never goes dormant (probably inherited from its Sinningia bullata ancestry).
They are all bloom-sized & range from 2 to 6 years old.? I STRONGLY recommend wide shallow pots for these.? I had some planted in narrow deep pots and struggled tremendously extricating them this weekend.? The small pots caused their shapes to be malformed, too.? I think they'll approach normal shape again in a few years in good conditions."

Bulbs:

4. Babiana sp. - low growing, purple flowers
5. Calochortus vestae
6. Geissorhiza sp. (probably inaequalis)
7. Spiloxene capensis
8. Watsonia humilis

Seeds:

9. Gloriosa modesta (Littonia modesta)
10. Nerine platypetala
11. Sandersonia aurantiaca

Thank you, Dennis and Mary Sue !!

Best wishes,
Dell

Tell when the pollen is dehiscing, but I don't know when the stigma is
receptive. In many plants, the two processes occur at different times to
avoid self-pollination. Is there some visual cue to this?

Usually yes, but the visual cue varies by genus.

Generally you'll be able to spot a physical change in the surface of the
stigma. The end may go from smooth to rough, or the tip may split, lengthen,
or become feathery. The best advice I can give you is to check the flowers
every day and watch the stigma. After a bit you'll spot the change and it'll
become obvious.

Often the change is pretty obvious once you know what to look for. In
Amaryllis, tip of the stigma splits into three and the ends look fuzzy. On
the other hand, with Brunsvigias (another Amaryllid), the stigmas never seem
to change and I have to guess when they are ready.

In Moraeas, the stigma is often a little flap, and as long as you can pry it
open and shove some pollen in there, it doesn't seem to matter when you do
it.

In Calochortus, the stigma starts off smooth and shiny looking. When ready
for pollen, the three parts of it (the stigmatic lips?) widen and flatten
and have a slight fuzz to them, like velvet. Many Tulips are similar.

(I should add that I think these changes are linked to pollen receptivity,
but I haven't done controlled experiments to prove it. I remember once when
I talked with an experienced Amaryllid breeder, I asked him about checking
the flowers for receptivity before pollinating them. He said something to
the effect of, "I pollinate them whenever I can, multiple times if possible.
I figure that gives me the best chance of having pollen there when the
flower becomes receptive.")

Hope that helps.
