Romneya Species, Coulter's Matilija Poppy, California Tree Poppy

I've just moved to Shingle Springs, CA and have a stand of Matilija Poppy growing - with no water - on a hillside - in drought season. Th...Read Moreey bloomed like crazy over the Summer. They are done blooming now. I'd like to try propagating with the seed method - but a have a few questions about when and how to do it?

1) When do I collect the seeds?
2) Do I need to store them in a dry place and wait until Fall to plant them?
3) I've heard about the need for smoke. I've also read you can soak them in 'rubbing alcohol for about 15 minutes to help weaken the seed coat (scarification) and speed up germination' (http://www.horticultureguy.com/2006/03/propagating-matilija-...). Has anyone else tried or been successful with this method?
4) If I need to wait until Fall to plant - do I do the smoke method before I store them? Or do I smoke them just before I plant them?

Thanks so much for your help!

We love this plant - it just suddenly appeared in our yard. There is one plant growing wild about a mile from us. We do nothing with it a...Read Morend it just produces beautiful flowers but it was a challenge finding out what it is - even the local professionals were unsure. Our climate is fairly dry, with summer fog blowing in and out, we are right on the Strait of Juan de Fuca so there is significant wind often. The soil is glacial deposits but our Matilija appeared in a raised bed. It has a very delicate scent that teases rather than overwhelms. We have Angels Fishing Rod propagating around the yard and now the Matilija and they just really dress things up this time of year. Neither of these plants require watering and the deer don't eat them. I didn't cut it back last year but maybe this fall I will try it and see what happens.

Their underground systems can spread vigorously - even travelling under a concrete driveway - according to my neighbour who has them growing in her garden. The old shoots can be cut back to the ground in spring.
They are a native to California and New Mexico.

Both my mother and I have had good luck with growing Matilija Poppys. We were able to take cuttings with us when we moved from Gig Harbo...Read Morer Wa to Seabeck WA. The plants adapted quickly to the new soil. Mine had no admendments and my mothers a little. She waters a bit better than I do, but both groups of plants have done well. They even survived a sudden freeze (dropped into low teens in less than 5 hours with harsh north wind last Nov 2010) They do spread quickly. I have one plant that came up from a runner, thanks to my husband removing the mother plant due to its invasivness. I am going to try and start some seed this year and hopefully have baby plants. We are planning on a major move to Texas, and I do not want to leave this star behind.

Do not over water. If you do it is less likely to bloom very much!

It is my favorite plant and it is loaded with flower buds about to explode!! The most important thing when you plant this shrub is to make sure it has PERFECT drainage and LOTS of sun!!

The soil in each place tends to be pure sand, exposed to wind, and sun, and the plants don't receive any other care. If happy, they'll spread like monsters and grow very tall.

I bought several at Valley Hills Nursery in Carmel Valley a month ago. Mine haven't spread out yet, but they've definitely grown taller, and all of them have small flower buds developing. This is a gorgeous plant and if you have the right soil, snatch them up.

For the record, Dublin is definitely not as warm (or dry, I suspect!) as California, but my Romneya certainly likes the climate here. It's rare here, though, I've only seen it in one other garden and even our Botanical Gardens in Dublin seems to be unsure where their plant is.

It sounds bizarre but various people have assured me that this works, and my experience squares with that. Not sure how well the plant will do here in north Florida: I had a potted one sent by mail and it didn't last long...overwatering? It didn't look in the best of health when it got here.

I have this Planted in Fort Bragg, California, in transistional sandy soil, from a potted specimen. Have seen this in several locations around Southeast Portland, OR where I collect seeds.

CULTURE: Difficult, but possible, to culture by root cuttings; personally I have had no success in two attempts), but the SEEDS are ONLY likey to germinate in media treated with SMOKE. Nitrite from combustion products has been identified as the primary germination trigger; not heat or ash. Smoke treatment of sand or use of charcoal among others has been described. Fifteen minutes of smoldering, not hot fast files has been mentioned in the literature as a requirement.

CONTROL: Should be easy to control by spading the roots.

MEDICINAL: This poppy species is helpful for various minor afflictions. The tea or diluted tincture, as a drug analgesia, works well as a wash for skin pain and inflammation caused by an allergic reaction, chemical irritation, heat rash, or mild burns or sunburns. As an astringent, it is a quality antimicrobial, and can be used as a powder to help with more common skin fungi. Though the diluted tincture reputedly tastes horrible, it does inhibits microbial growth in the mouth, lessens gum sensitivity, and decreases plaque buildup (see recipes for a Matilija Poppy mouthwash). Painful and debilitating but not emergency-level bacterial gastroenteritis can be soothed with the tea or tincture, simultaneously helping to inhibit the bug, lessen the pain and cramps, and act as a mild sedative.

I first saw the Matilija Poppy in a Botanical Garden in Claremont California. Right away I fell in love with it. After having the sales g...Read Moreirl in the gift shop print out some information for me on the flower I right away stopped by my local nursery in Santa Clarita and purchased a 5-gallon plant. It has numerous buds on it. However, I didn't realise until i got home that I closed the car door on one of the branches and broke one of the branches just below the poppy buds. I cut the branch just below the break to clean it up a bit.

I also soaked 100 seeds the same day. I soaked the seeds for 24 hours. I gathered dead Christmas tree branches and dried oak tree leaves. I placed ordinary California soil on a fine, wire mesh, flat, bacon grease spatter stopper. In my fireplace I started a fire with the leaves and added pine branches. When fire died down to smolder I held the the soil over the smoke for 15 minutes. I added leaves and branches as needed to keep fire going but only smoked over a low, smoldering fire. When soil had cooled I placed a coffee filter on the soil and placed the seeds on top. I covered with another coffee filter and sprinkled smoked soil on top of 2nd filter.I dampened with drops of water from an eye dropper till wet. I covered with plastic wrap and placed outside to expose seeds to temperature fluctuations in November. Seeds began to sprout 2 1/2 weeks later. I planted all ten seed today.There are more seeds beginning to sprout.

Update May 21, 2006

I was able to transplant one seedling into the garden. It was doing well until my "gardener" hit it with Roundup. :( Matillaja Poppy from a pot is healthy and spreading. It is 4-5 feet wide now. I have tried to propagate from suckers two times last winter--no luck. I am going to try the seeds again but this time I sprinkled them on damp soil in a big pot. Smoked some potting soil as I did 1 1/2 years ago. Covered the seeds with smoked soil, watered and covered in plastic. Set outside. I should know in 3 weeks if they have germinated.

Update June 13, 2006

It has been three weeks and it looks like I have about 20 out of 100 seedlings so far. When the seedlings started poking out of the soil I took off the covering let them get a little sun each day. Moistened top of soil lightly to prevent the seeds from drying out but not much b/c overwatering kills them.

According to what I was told, this plant is native to two relatively small disjunct areas in the U.S. - in Ventura County, CA near Ojai, ...Read Moreand in Riverside County, CA. In the wild, the seeds will only germinate after a fire, though the plant spreads freely from runners. There are a couple stands that where planted at what is now Malibu Creek State Park and they are very popular flowers with park visitors.

The smell of the flower is rather strange, kind of like rotten fruit.

I have never tried growing this plant at home. I have read that it is too invasive for the average home garden.

They are beautiful flowers and not hard to take care of.

In San Diego county alone there are 7 species of Eschscholtzia. (Info from Beauchamp's A Flora of San Diego County.)

I realize how large it can get, but it can be transplanted via cuttings according to the Horticulture lab at UC Berkeley, one lady said she had them all over her yard. The burning of seeds should work well, I could'nt do that where I lived in Southern Ca in Chino Hills, I could of started a fire. Everywhere I see one, I just go crazy!

The nursery owner in town says it is rare here and that it would be hard to replace. I need to move it, but will try to take the babies into pots first, to see if they survive, before I try to move the mother. It seems to do well in our mild, wet winter, dry summer climate that we've had this year, with no extra water after March.

To the best of my knowledge, the common name for Romneya is the Matilija poppy.

Seed difficult to start. In fall, make seeds germinate by mixing them with damp potting soil in non-flammable flat(or line flat with strong foil), burn pine needles on top of flat for 1/2 hour, then water flat and maybe they will sprout. Really, not a joke.
