Ask Lil E. Um received these questions
and with the help of Dr. Gene Fox, North American Lily Society President,
sent a quick response to a very happy college student. Here is the
email:Message: Hello, my name is Ashley and I am writing
a paper about different flowers and I would like some information
about the lily. Please help me with any of these questions that you
can.
1) Is the lily sporophytes or gametophytes?
2) Can you see the gametophytes?
3) Is the lily complete?
4) Is the lily perfect?
5) How is the lily pollinated and what clues support your reason?
Thank you so much for your help.
Ashley
Reply: Dear Ashley,
My answers are about lilies (true lilies) as in Latin Lilium
1. Lilies make seeds and are gametophytes. No true lily makes spores,
so none are sporophytes.
2. When you say that, I believe you mean, "Can you see the 'gametes?'" One
can see the male gamete, which is pollen as it is on the end of anthers
and it, can become a brown smudge on your clothes if you are not
careful. The pollen is made up of hundreds of tiny spherical grains.
One needs a microscope to see the individual grain of pollen. The
female gamete is inside the ovary or what becomes the seedpod. If
the pods are cut open or dissected before pollination, one can see
the female gametes or ovules (eggs).
3. The lily has a "complete" flower in that it has both
male and female parts.
4. Yes, lilies have both the pistils and the stamens in the same
flower, so it may be said to be "perfect". The word, "monoclinous" is
actually the technical term for perfect in that case.
5. The lily is pollinated by transferring the pollen from the stamens
of one lily flower to the stigma of another lily flower. One knows
the flower is pollinated if, after the petals drop away, the ovary
(seed pod) starts to swell up as seeds grow inside it.

Lil has received several questions
from a gardener who would like to learn more about their lilies. We've
asked experienced lily grower and hybridizer, Jeff Stiller for his
advice. Jeff's response is included below each question. I
hope Pat and our web visitors find this information useful. This
is also a great time to promote this year's largest lily show in
North America. The North American Lily Show is being held in
Eau Claire, Wisconsin, July 12 - 16, 2006. The show itself
will be free and open to the public from Friday afternoon, July 14
through Sunday July 16. Folks who officially pay their registration
fee may attend the symposium of speakers who will cover a number
of lily culture topics on Thursday and Friday, July 13 & 14. For
more information visit the website of our sister regional, Wisconsin
Regional Lily Society www.wrls.org or
the website of the North American Lily Society www.lilies.org.
Jeff is also a member of WRLS and is busily preparing for the NALS
show.
Message: Hi, Lil
I have a lot of questions now that my lily garden activities
are expanding. I've received a few damaged bulbs this year that
I've ordered on-line. The stems had grown 2 or 3" and then snapped
off right at the base of the stem. I've heard that the bulb will
never grow and all it would be good for is scale propagation. I've
also heard that I should plant the bulb. While it won't do anything
this year, it should be OK for next. Which is it? Pat Hunter
The bulb has stored energy in the outer scale portion. The center
portion is where new growth for this years flower starts Some
bulbs recover in the following year & some do not. It is a 50/50 chance.
The same goes for the scales as it is best to scale in the fall or
after flowering. Again 50/50. Conditions in which the bulbs were
stored are a major factor. If outer scales dehydrated too much, or
if the bulb is heavily contaminated with mold it may affect
the year's growth. Be sure to check out the bulb sales from
regional lily societies. They acquire bulbs locally and from
trusted vendors. Jeff Stiller
I haven't had much luck planting orientals in the fall, but
spring planted ones do just fine. Can an oriental bulb be held
over winter successfully in a refrigerator? It is hard
to find a oriental that will survive in Minn/Wisc for more than
a year or two. They need conditions we have a hard time duplicating:
acid soil, dry winters, and a long growing season. The long growing
season being the hardest thing to offer as the bulb needs time
to grow & build up energy. Our frosts & winters come
too soon. I grow my orientals in pots. They are started indoors
to get a head start. In winter they are stored in a cool place
with peat moss. They still do not last, so like some annuals I
just reorder them, as they are too nice not to include in my garden.
I know that a lily bulb will pull itself down if it's not happy
with its planting depth, but some of mine seem to be wearing running
shoes. I see them popping up several inches away from where they
were originally planted or in some cases where they have been planted
6 or more inches apart, coming up right next to one another. Is
there anyway to contain the bulbs so they come up where they are
planted?
No. It is a survival trait.
I also have some questions about propagation:
1. When propagating scales, once the bulblets have set and roots
start growing, how deep do you plant the scales? The
tip of the scale should be showing. I grow mine in small pots
for a year & in fall plant them out in the garden.
2. What do you do with a scale that has 2 or three bulblets
attached? Do you cut the scale and plant the bulblets separately
or do you keep them all together for a time?Plant as advised
above or if bulblets are larger than a pea, separate and more may
grow on the scale.
3. I am assuming that asiatics and LA bulblets can overwinter in
an outside bed in Minnesota. Is that a correct assumption? What about
orientals, trumpets, martagons and other interdivisional crosses; do
they need to be lifted and can they stay in the refrigerator all winter? To
answer this question it would be best to attend a local lily society
meeting and talk to experienced regional lily growers
4. How long does it take to for a bulblet to reach maturity?
At some point, should the bulblets be planted in pots that have
been sunk in the ground for easier retrieval? Some
bulblets may flower in two years, others may need more time depending
on the variety. True plant maturity will take longer, but
at least you will see what to expect from the lily in the future. |

: When does a person apply bone meal to lilies?
We are happy to answer your
question as it has added importance at bulb planting time. We
asked one of the most experienced lily growers in North America
for his advice, Dr. Gene Fox, current President of the North
American Lily Society. Here is his response.
"Bone meal is fraught
with a ton of problems. It does attract animals and rodents who
dig up the bulbs in a quest for the bone meal even if it is put
in the hole. Sometimes insects that are harmful to the bulbs
take up residence because of the food value in the bone meal.
It also may initiate bulb rot if in contact with the bulb. Since
bone meal is in short supply due to bans for health reasons,
the companies have been stringing it out (extending it) as "Bone
Meal Plus" which is a smidgeon of bone meal and ordinary
chemical fertilizer. Unlike bone meal, this mix can burn plants
or bulbs or at best induce fast growth and hence open the door
to botrytis in the too lush green tissue.
Besides attracting animals,
bone meal, after it is watered in by rains or such, attracts
tree roots aplenty if any are nearby. Tree roots rob all the
soil nutrients and the lily bulbs whither. Also, bone meal is
not balanced. It contains really only one (P) of the magic three
ingredients of say 7-7-7 or 10-10-10 or NPK. Bone meal, because
it is not balanced, causes lilies to increase by division into
multiple smaller bulbs so small they will not be big enough to
bloom. Taking the clump up that has been so fertilized and spreading
the little bulbs out in non-fertilized soil still takes a few
years to get them back to bloom size and settled down from the
division madness.
Finally, I would not touch
it, because its contents are ground up bones and general stuff
like skulls and spinal bones that may include brain cells and
spinal cord cells on them and in them. These materials are the
center in beasts that may be infected with Mad Cow Disease or
BSE or as it is called in humans, Jacob-Kreutzfeld disease. The
bacteria can live for decades in the soil and cause potential
infection a decade or so down the road.
Garden supply centers push
bone meal as they can triple or quadruple their sales return
by selling it with tulip bulbs etc. There was a time, early last
century when other fertilizers were not available and bone meal
was in general use. A lot of the old garden writers recommended
it and people in the field tend to recycle old methods without
holding them up to the light of modern knowledge. Almost every
garden columnist writes and perpetuates nonsense like, "always
use a "little bone meal," because they write and do
not get their hands dirty in the garden or read widely and get
their eyes opened.
I would use no fertilizer
year one, except good compost or good soil not used to grow lilies
before. The next year when the lily is in full bud and every
second year thereafter, unless inordinately wet, I would use
a tablespoon of 7-7-7 or 10-10-10. Thereafter, I would use it
every second year at bud time, unless the lilies got too lush,
in which case I would miss a year or three. I would spread it
on top of the soil near the bulb clump."
