Mystery Bulbs / Re: Scilla or?
April 24, 2024, 07:50:17 PM
I also posted the picture on Instagram and was pointed by Rimmer to Hyacinthoides mauritanica ssp vicentina.  Or Hyacinthoides vicentina if you prefer.  This seems to be the best fit when I look at it closely.  It doesn't have the really blue anthers of the Tractema verna.  Whatever it is I rather like it and hope to spread it around. 
Mystery Bulbs / Scilla or?
April 22, 2024, 08:12:42 PM
Last fall I planted out these no name bulb which bloom for the first time this year.  No idea what it is. I've looked a scilla, hyacinthella, hyacinthoides, fessia and merwilla pictures on the wiki and don't see anything that looks like it. Doesn't smell like an allium. Its starry light blue flowers are rather pretty little things.  Whatever it is, it's hardy-we went down to 15 last winter. 

Any ideas?  Is this a plant to be feared?

All the seed has been mailed so it's time for some grab bags.  

I have three grab bags available for $15 each, including postage.  I will pick three names at random from those who apply by tomorrow,  November 8th at 8 pm PDT.  This grab bag drawing is only available to folks with a US address.  I just don't have time right now to deal with the post office again.  

To apply send me an email with the following:

Subject line must read: Seed Exchange 15 Grab Bags

Your name and address as it would appear on an envelope.

Do not respond to the list.  Responses to the list will not be considered.  Responses that do not follow the above instructions will also not be considered.

Seed Exchange 15 is now open for orders until Monday, October 30 at 5pm PDT. You must be a paid up PBS member to order seed. Non-members may not order seed. Members in arrears for past Seed or Bulb Exchanges may not order seed.  I check. If you have any questions about your payment status please check with Arnold at

Jane McGary has generously donated seed of the rare Tulipa regelii.  This plant has marvelous corrugated leaves and to see it is to want it.  I also received generous donations of pink forms of Calochortus albus.  There should be enough of these pink and red forms to go around.

Some donors have large collections of a specific genus.  Unless stated that the seed is hand pollinated (HP) you should assume there is a possibility of hybridization. 

I will randomize the orders and then fill one or two requests per person. After filling everyone's top requests I will then go back through the orders and fill the rest of the requests.  This gives more people a chance to get some of the rarer seed and prevents the top few from getting it all. 

Any order submitted by the deadline has an equal chance of being filled first. All orders should be submitted to with "SX 15" in the subject line.  Do not post your orders to the list!

The packet labels do not include additional information such as color, parents etc.  You'll need to transfer that information from the list.  Donor information is also available from the list.  In most cases the list now includes the number of packets available and if extra seed is available to make additional packets. 

Rules for ordering
Your name, address, and email should be listed first on your order.  Give your address just like you would on an envelope. Don't string it across a line; I can't tell what goes on what line. This is particularly important for foreign addresses. 
For example:
Sue Bulbcrazy
2654 Bulbnut Ln
Bulbnutsville, OR 92013

Seed is $2 per packet.  Your bill will reflect postage credit for any previous seed exchange submissions.  Domestic postage will be charged at $4 per order.  All previous orders shipped for under $4 to slightly over $4 per padded envelope so I am standardizing postage at $4 per envelope for all domestic orders.  The extra over the postage costs will help pay for the mailing envelopes. Foreign orders will be charged at cost.  You will receive a bill in your envelope which you can pay online at

List your 15 first choices vertically in order of preference.  For example:
14 Narcissus cantabricus
15 Romulea rosea
13 Narcissus bulbocodium
If you list I preference I don't have to guess what you'd like most.  Mind reading has never been a strength of mine.
I must have both the seed number and name!

Unless you tell me differently I will assume you'll accept seed from a different donor if seed from your first choice donor is sold out.

List your alternates in order of preference.  You can also include notes to help me pull seeds that will make you happy.  For example; "any gladiolus seed ok as alternate".  If you don't list alternates I will only send the first choices I have available. I am not limiting people to 15 packets but if you want extras I will process the amount in excess of 15 packets after I am done filling the other orders.

No seed orders from countries that require a phytosanitary certificate. New Zealand orders are at your own risk for postage costs. The most recent orders to New Zealand have gone through fine but there are no guarantees.

It is important to follow the ordering instructions.  Orders that don't, and drive me crazy trying to fill them, may be put at the bottom of the stack!  Don't make me do that. I'm feeling a bit cranky about people who don't follow instructions.

Contact me with any questions about the SX procedure, but not about the offerings, at  Questions about germination or the suitability of the seed for your climate should be posted on the forum. 

List posted in next message.

Hi all,
My deadline for receiving seed for the fall exchange is a firm October 15th.  Any seed received after that date will be held for a subsequent exchange.  I'm leaving mid November for a trip to Europe and want to have this exchange all wrapped up before I go.

The US seed exchange is now open for donations until further notice. Please read ALL the instructions carefully and contact me at if you have any questions./size]
The seed exchange welcomes all non-ephemeral geophyte seed, but not in unlimited quantities.  I only need enough seed for a maximum of ten packets unless the seed is unusually desirable.  For more common seed I plan to only make up five packets.  Based on past experience this should be enough. Examples of seed with extraordinary desirability would be paramongaia and worsleya.  If you have seeds of these I'd really like to hear from you! Bulbs of these plants are either not available commercially or are very expensive.  For most seed a tablespoon is quite sufficient for five to ten packets.  If your seed is huge (pea size or bigger), it would be appropriate to send a bit more.  Do not send me massive quantities of seed; I will just have to throw it out.
Wild collected seed, with geographic collection information, is very welcome. Wild collected seed must collected in accordance with local laws and applicable regulations.
Please label each bag with the scientific name of the plant and your own name so that all donations are clearly identified and can be referred to the donor. I can take as small as one packet's worth of seed. 

If you are willing to prepack your seed please let me know how many free seed envelopes to send you. I get my seed envelopes from NARGS and these are what I will send you.  Be sure to include your mailing address.  Prepacking the seed will greatly reduce my workload.   Each envelope should have at least enough seed for a pot, generally at least 10 seeds. Rare seed can have less. You don't need to label each packet individually; just clip or rubber band them together.  If you're unsure how many seeds to packet just send me the seed and I'll pack it.  If you think your seed will be especially desirable and you have extra seed you can send it in a separate envelop and I will pack it as needed.
You can also use your own envelopes to prepackage seed but they must 2" to 2.25" wide and 3" to 3.5" high.  The NARGS envelopes and #1 coin envelopes meet these qualifications.  Please do not package seed in plastic envelopes unless they are small enough I can easily pop them into the glassine envelopes. Plastic envelopes alone have a nasty habit of slithering to the bottom and hiding from me as I pick orders.   All the packaged seed is organized in coin boxes for easy and quick order filling.  This is why I need seed envelopes of a particular size. 
No one is required to prepackage seed.  I realize not everyone has the time, finger dexterity or inclination to package seed.  Jane and I have time to package seed.  Please however make sure your seed is clean.  Nobody like dirty seed.
If you wish to donate seed from outside the US please let me know.  I have a Small Lots of Seed Permit I can send you for your donation.  This form is required for all seed entering the US from foreign countries.

As a donor you will get a credit on seed equaling the postage you paid (rounded to the nearest dollar) for your donation.

Please remember that you must be a fully paid member of the PBS to order from our seed and bulb exchanges. You do not have to be a donor to order, all US and Canadian members can order from the US seed exchange.  EU members have a separate seed exchange due to the requirement for a phytosanitary certificate for entry into the EU.

I anticipate the seed exchange will be open for donations until late September ish when it will be closed to prepare for another distribution

All the trillium seed went out Friday which means it should arrive in your mailboxes this week.  I have good news and bad news.  The good news is I had plenty of western trillium and enough of the eastern trillium that most people got what they wanted.  The bad news is I only had two packets of Trillium underwoodii and some seeds were in small supply so the seed packets only contain five seeds.  

As soon as you get the seed plant it immediately, and by immediately I mean that day or the next.  The seed is packed in little plastic envelopes with a bit of moist paper towel.  This means there isn't much air and the seed is likely to rot if kept in these packets very long.  If for some reason you can't sow it immediately remove the paper towel and throw in some VERY slightly moist potting mix or vermiculite or some such to hold it.  Even better transfer the seed to a regular baggie and add more moist soil.  The idea here is to keep the seed moist, but not soggy, and aerated.  

Some of the western trilliums may have some elaisome still attached.  If it's gooey wash it off, otherwise you can just sow it with the elaisome.  I've done this before and had good germination.

General Discussion / Re: cleaning Trillium seeds
July 29, 2023, 06:44:16 PM
I use the throw them in a plastic bag and let the elaisomes turn to mush and then wash them.  However it doesn't hurt at all to just plant them with the elaisomes.  That's how I got my kurabayashii.  Someone brought some ripe seed pods to our NARGS chapter picnic and told us to plant them immediately.  I squished them out of the berries the next day and planted them, elaisomes and all.  I had fabulous germination the next spring.
This seed exchange is first come, first served.  It closes July 30 at 5 pm Pacific Daylight Time.

This is a special pop-up mini seed exchange for trillium seeds and a couple of other species.  Unlike the regular seed exchanges this one will be first come, first served.  Orders will be numbered in the order they come in so don't dilly-dally.  All these seeds, except the Arisaema flavum, will need to be sown immediately.  DO NOT ALLOW THEM TO DRY OUT. They will all be shipped moist in plastic bags.
As with other seed exchanges the top of your order must have your postal address with your email below (in case I have questions later).  If I have to chase you down for this information your order automatically goes to the bottom of the stack.  
Seeds will be $2 per packet with a minimum of 5 seeds per packet.  Order by the name in bold.  In most cases there will be at least 10 seeds but if there is high demand you may only get 5 seeds per packet.  Shipping will be $4 domestic, international shipping at cost. Send your orders to

Here is some information from Charles regarding the hardiness of southern trillium:
"Hardiness is mostly related to late freezes for plants that are very early. Trillums do have antifreeze, but a few from north FL ( decipiens and north FL lancifolium) are so early that folks in northern states and Canada will find that they will emerge and bloom before hard freezes. Since they all grow fine outside for me in my 7b north Georgia garden, I do not have a reason to know how far north they can be grown outside. But Fred Case (author of the book " Trillums") stated in his book that decipiens and early underwoodii were not good outdoors in his Michigan garden due to repeated hard freezes after they emerge. Note that the Alabama piedmont underwoodii seeds I sent you are later to emerge and bloom and might do Ok in most northern gardens. The underwoodii found in north Florida and adjacent SW Georgia is VERY early, but I did not get seeds from those this year."
Trillium cuneatum
Trillium decipiens.  Very early, should be a pot plant in colder climates.
Trillium flexipes.  Southern form NE Alabama.  Heat tolerant.
Trillium foetidissimum. Native to eastern Louisiana and southwest Mississippi.
Trillium lancifolium.  Very early north Florida form.  Should be a pot plant in colder climates.
Trillium oostingii. South Carolina.  Mostly yellow-green flowers with a few dark purple. Rare form
Trillium pusillum
Trillium underwoodii. Later Alabama Piedmost form.  Better for colder climates.
I have fairly low quantities of these southeastern trilliums so early bird gets the worm. 
Donated by me, Jan Jeddeloh. 
Trillium albidum.  Hand pollinated. Pod parent is a particularly nice form.
Trillium kurabayashii
Trillium (kurabayashii x albidum) X albidum.  The pod parent is a mid-pink with nice wide petals. It is a cross I made some years ago.  I made this cross to try to get a pale pink.  I've planted a fair bit of the seed myself.  
I have fairly large quantities of these trilliums.  Let me know about how many seeds you would like but if you're really greedy, and I have the seed, I may charge you an extra $2 for a generous packet.  
Fellow shade travelers.
Amorphophallus kiusianus 
Arisaema flavum This is left over from SX13 but it's a nice shade plant that deserves some love.
I just realized I forgot to post the grab bag announcement in the forum.  Oops, sorry about that. As a result I'm extending the deadline until July 19th at 5pm.  

Here's my email to the list with the ending date and time corrected.

I found this scholarly article about E. japonicum seed germination. Since japonicum is closely related to sibiricum the methods it suggests seem like a good place to start.

So for the dens canis tribe it appears you don't want to start with cold as Mark suggests but rather with a warm moist period.  This would more closely match what they get in the wild.  I actually tried this using the paper towel method on one dens canis type (can't remember the exact species) and got germination but was not ultimately successful in growing on, partly because I wasn't in sync with the seasons.  

Here's the abstract of the article which gives you most of the nitty gritty.

Erythronium japonicum (Liliaceae) (Japanese name, katakuri) is indigenous to Japan and adjacent Far East regions. We examined their embryo elongation, germination, and seedling emergence in relationship to the temperature. In incubators, seeds did not germinate at 20°/10° (light 12 h/dark 12 h alternating temperature), 20°, 15°, 5°, or 0°C with a 12-h light photoperiod for 200 d. They germinated at 15°/5° or 10°C, starting on day 135. If seeds were kept at 20° or at 25°/15°C before being exposed to 5°C, the seeds germinated, but if kept at 25° or 30°C they did not. Embryos at 25°/15°C grew to half the seed length without germinating; at 0° or 5°C, embryos elongated little. Embryos grew and seeds germinated when kept at 25°/15°C for 90 d and then at 5°C. In the field, seeds are dispersed in mid-June in Hokkaido and in Honshu, mid-May to mid-June. Seeds do not germinate immediately after dispersal because the embryo is underdeveloped. Embryos elongated at medium temperatures in autumn after summer heat, and germination ends in November at 8°/0°C. After germination, seedling emergence was delayed, and most seedlings were observed in early April around the snowmelt when soil cover was 2–3 mm.
Maybe try sowing a couple of seeds now and save the rest and sow later?  Hedge your bets. 

Also Mark, the seed I promised you will go out tomorrow.
That is impressive problem solving Mark.  Maybe with your work we can finally get a second clone in the US.  I sure hope some of the seed germinates.  Where did you get the idea of using Gibberellic for this purpose?  

Lily growers sometimes get seed from a single clone using the cut style method?  Have you ever tried that?

Did you tell the clerk at the liquor store that you were buying Everclear, the drink of hardcore alcoholics, for plant pollination?  If you did I'm sure that was a first for them.
