    • Out of the Wilds and Into Your Garden Gardening with Western L.A. County Native Plants Project SOUND – 2011 (our 7th year) © Project SOUND
    • Fabulous Ferns C.M. Vadheim and T. Drake CSUDH & Madrona Marsh Preserve Madrona Marsh Preserve February 5 & 8, 2011 © Project SOUND
    • What do you picture when you think of ferns? © Project SOUND
    • http://www.cityprojectca.org/blog/archives/835Fern Dell at Griffith Park © Project SOUND
    • Ferns go back a long ways…> 360 MYA http://taggart.glg.msu.edu/isb200/cswamp.jpgFerns had their heyday in the Carboniferous Period (360-300 MYA) - 100 MY before the dinosaurs http://www.kgg.org.uk/alethopteris4.jpg © Project SOUND
    • The move from water to land was difficult – even though conditions were a lot more tropical (humid/watery) back then  Need:  a rigid structural system for support  anchors to the ground (plants) or ways to move around  a vascular system to transport water and nutrients All this takes a long time and the ability to change – a lot © Project SOUNDhttp://cmex.ihmc.us/VikingCD/Puzzle/Advance2.GIF
    • Ferns were among the first plants with avascular system & lignin support systemhttp://media.photobucket.com/image/plant%20evolution%20tree/kofh/Genesis/plantkingdom.jpg © Project SOUND
    • They also evolved a more sophisticated means of reproduction – alteration of generations (e.g. ‘sex’) © Project SOUND
    • All higher organisms(including ferns & humans) have alternation of generations In sexual reproduction, only ½ of a parent’s chromosomes are passed on to the egg/sperm/spore (they are the (n) generation) When fertilization occurs the new embryo (and the resulting adult) have the full complement of chromosomes (2n generation) Sexual reproduction allows a species to recombine genetic traits © Project SOUND
    • So ferns – like all other higher plants – do have sexIt’s just not quite as efficient - and it requires water © Project SOUND
    • Ferns now make up only a fraction of theliving plants – in part due to less efficient sexhttp://crescentok.com/staff/jaskew/ISR/botzo/plants.gif © Project SOUND
    • What are the ferns? (summary)  Ferns are vascular plants differing from mosses by having true leaves.  They differ from seed plants (gymnosperms and angiosperms) in their mode of reproduction—lacking flowers and seeds.  Like all other vascular plants, they have a life cycle referred to as alternation of generations, characterized by a diploid sporophytic and a haploid gametophytic phase.  Unlike the gymnosperms and angiosperms, the ferns gametophyte is a free-living organism. http://www.perspective.com/nature/plantae/ferns.html © Project SOUND
    • The American Fern Society Over 100 years old – established in 1892 > 900 members worldwide (one of the largest international fern clubs in the world. Objective: fostering interest in ferns and fern allies. Wide range of publications & activities – good way to learn more about wild ferns from experts and meet other people with a similar passion for ferns. Web site - http://www.amerfernsoc.org/ is designed to expand on this exchange of information with amateurs and professionals around the world. © Project SOUND
    • Taxonomy of the Ferns – in a state of change http://www.amerfernsoc.org/ © Project SOUND
    • The living fern-allies can be divided into fourclasses:  Psilotopsida:  ?Only living member Psilotum (whisk ferns)  Probably the most primitive vascular plant still in existence - may be directly related to the first vascular plants on land.  Lycopodiopsida:  Represented by the Selaginellia (Spikemosses), Lycopodium (clubmosses), and the Isoetes (Quillworts).  Equisetopsida:  Represented today by only one genus, Equisetum (Horsetails). © Project SOUND
    • The living fern-allies can be divided intofour classes:  Polypodiopsida (Pteropsida)  The true ferns  By far the most numerous of all of the fern-allies.  Nine sub-classes (Families), about 250-300 genera and over 12,000 different species alive today. © Project SOUND
    • Selected Families/Genera used in gardens  Family Adiantaceae  Genus Adiantum (Maidenhair Ferns)  Genus Cheilanthes (Lipferns)  Family Blechnaceae  Genus Woodwardia (Chain-ferns)  Family Dennstaedtiaceae  Genus Dennstaedtia (Hay-scented fern)  Genus Pteridium (Bracken)  Family Dryopteridaceae  Genus Cystopteris (Fragile Fern)  Genus Dryopteris (Wood Ferns)  Genus Matteuccia (Ostrich Fern)  Genus Onoclea (Sensitive Fern)  Genus Polystichum (Sword Ferns)  Genus Woodsia (Woodsias)  Family Polypodiaceae  Genus Polypodium (Polypodies)  Family Thelypteridaceae  Genus Thelypteris (Beech Fern) © Project SOUND
    • Selected Families/Genera used in gardens  Family Dryopteridaceae – Woodfern Family  Genus Cystopteris (Fragile Fern)  Genus Dryopteris (Wood Ferns)  Genus Matteuccia (Ostrich Fern)  Genus Onoclea (Sensitive Fern)  Genus Polystichum (Sword Ferns)  Genus Woodsia (Woodsias) © Project SOUND
    • The Sword Ferns - genus Polystichum http://hardyfernlibrary.com/ferns/listSpecies.cfm?Auto=60 Western Sword Fern 135-160 species worldwide – mostly temperate regions Usually live in moist places Have typical fern structure/anatomy © Project SOUND
    • Parts of a typical fern http://www.davidlnelson.md/Cazadero/Ferns.htm Leaf = frond Midrib of leaf = rachis Petiole = stalk, stipe Leaflets = pinna Stem/stalk (rootstalk) = rhizome (like rhizome of higher plants) Roots = roots © Project SOUND
    • * Western Sword Fern – Polystichum munitumhttp://www.nwplants.com/business/catalog/pol_mun.html © Project SOUND
    • * Western Sword Fern – Polystichum munitum  Western N. America, primarily coastal states, from AK to Baja  In CA, almost always below 2500 ft.  Favored habitat: the understory of moist coniferous forests at low elevations – locally, San Gabriel mtns.  It grows best in a well-drained acidic soil of rich humus and small stones.http://www.efloras.org/florataxon.aspx?flora_id=1&taxon_id=200004619 http://www.backyardnature.net/n/x/sword-fn.htm © Project SOUND http://en.wikipedia.org/wiki/Polystichum_munitum
    • Fern pinna may be divided into pinnules or lobes  1 times pinnate – simple [Sword Fern]  2 times pinnate – more complex [Wood Fern]  3 or 4 times pinnate – complex (look lacy) [Maidenhair & Lipfern] © Project SOUNDhttp://bss.sfsu.edu/holzman/courses/Fall00Projects/swordfern.html
    • Western Sword Fern – corresponds to most people’s notion of a fern  Size:  3-6 ft tall  spreading to 3-6 ft wide  Growth form:  Upright growth habit  Height depends on light – taller in dense shade  Evergreen leaves in clumps of 100 or so – moderate spread rate  Long-lived  Foliage:  Medium to dark green  Single pinnate ( 1 times pinnate) with alternating pinna  Fronds unroll, forming fiddleheads© 2008 Matt Below © Project SOUND
    •  A sorus (pl. sori) - a cluster of sporangia The fern sorus (structures producing/containing spores)  Form yellow/brownish mass on the edge or underside of a fertile frond.  In some species, sori are protected by a scale or film of tissue called the indusium, which forms an umbrella-like cover.  As the sporongia mature, the indusium shrivels. The sporangia then burst and release the spores.  The shape, arrangement, and location of the sori are often valuable clues in the identification of fern taxa.  May be circular or linear.  Arranged in rows or randomly  Location may be marginal or set away from the margin on the frond lamina. © Project SOUNDhttp://www.biosci.ohio-state.edu/pcmb/osu_pcmb/pcmb_lab_resources/images/pcmb300/cfern2/reproduction3.jpg
    • Reproduction by spores Ex: Sword Ferns  Sword fern sori occur on the undersides of normal-sized pinnae more generally distributed along the frond.  Each round sorus is composed of dozenshttp://www.backyardnature.net/n/x/sword-fn.htm of spherical items. Those are not spores, but rather stalked, baglike sporangia filled with several spores.  When the sporangia are ripe they burst, release the spores, and the wind carries the spores to new locations  If environmental conditions are just right, they germinate to form fern prothalli, from which eventually new ferns will emerge.© 2008 Keir Morse © Project SOUND http://www.answers.com/topic/dudleya
    • Sword Ferns are  Soils:  Texture: well-drained loams are forest floor plants best  pH: acidic (4.0 – 7.0)  Likes lots of humus  Light:  Part shade to quite dark full shade  Water:  Winter: plenty  Summer: moist soils – Zone 3  Fertilizer:  ½ strength fertilizer fine  Organic mulch – leaf litter is optimal  Other: difficult in very hot gardens© 2008 Matt Below © Project SOUND

    • Giant Chair Fern: a garden favorite  From California Native Plants, Theodore Paynes 1941 catalog: "The most useful of the native ferns, having long graceful fronds of a vivid shade of light green, often 4 to 5 feet in length. Creates a wonderful effect on a shady bank or under trees, and very striking when planted against a wall or building in a shady spot. Very hardy and easy to grow. Gallon cans, 50c; 5 gallon cans, $1.50." © Project SOUND

Alfred Brousseau, Saint Marys College © Project SOUND
    • Victorian ‘Pteridomania’  Pteridomania or Fern- Fever was a craze for ferns. Victorian decorative arts presented the fern motif in pottery, glass, metal, textiles, wood, printed paper, and sculpture, with ferns "appearing on everything from christening presents to gravestones and memorials."http://www.georgeglazer.com/prints/nathist/botanical/fern.html © Project SOUND
    • Victorian ‘Pteridomania’ (Fern Mania)  The interest in ferns began in the late 1830s when the British countryside attracted increasing numbers of amateur and professional botanists (male and female).  People of many different social backgrounds sought out the species and varieties describedhttp://en.wikipedia.org/wiki/Pteridomania in the fern identification books to press the fronds in albums or to collect fern plants to grow in their gardens or homes.  Some ferns were, unfortunately, collected out of existence Wardian Case © Project SOUND

    • The Maidenhair Ferns  ~ 200 species of ferns in the family Pteridaceae (though some researchers place it genus Adiantum in its own family, Adiantaceae)  Name comes from Greek, meaning "not wetting", referring to the fronds ability to shed water without becoming wet.  The highest species diversity is in the Andes in South America. Fairly high diversity also occurs in eastern Asia, with nearly 40 species in China.  Distinctive in appearance, with dark, often black stipes and rachises, and bright green, often delicately-cut leaf tissue.  The sori are borne submarginally, and are covered by reflexed flaps of leaf tissue which resemble indusia.  Generally prefer humus-rich, moist, well- drained sites. Many species are especially known for growing on rock walls around waterfalls and water seepage areas.USDA-NRCS PLANTS Database / USDA NRCS © 2001 Larry Blakely Many species common in horticultural trade for a long time © Project SOUND

    • Characteristics of CA Polypody  Size: 20” tall; individual plants ≈ 25” wide – but often grow in spreading clumps  Leaves:  Simple for fern – many leaflets with serrated edges  Drought deciduous – dies back in summer  No flowers: Sporangia are grouped in round sori on the underside of the leaflets.  Rhizomes (underground stems) – relatively slow- spreadinghttp://www.calflora.net/bloomingplants/californiapolypody.html http://www.sci.sdsu.edu/plants/s dpls/plants/Polypodium_californi © Project SOUND cum.html
    • Growth requirements: not your eastern fern  Sun: part-shade to full shade; can tolerate full sun only right along coast, with adequate water  Soils:  Any well-drained  Does not tolerate alkali soils  Water:  Moist in winter-spring – even tolerates flooding http://www.davidlnelson.md/Cazadero/Ferns.htm  Gradually reduce water for summer/fall dormancy – must haveProbably the easiest local dormant periodfern for the garden;  Nutrients: probably benefits fromlocation is everything organic mulch; not a “big eater” © Project SOUND

    • 9 Easy (if you are patient) Steps:Growing Ferns: 1) You will need a clear plastic container (supermarkets cake container). This will ensure high humidity. 2) The potting soil must be good quality not a generic brand - very important. 3) After putting the soil in the container dampen it. It should feel like the humus soil you would feel in an oak forest. Not too damp not too dry. To kill bacteria and fungal spores place the container in a microwave oven and heat for 3-5 minutes (until it is steaming pretty good). Be careful, too long and the container will begin to melt. Then let the soil cool for about an hour. 4) Sprinkle the spores on top of the soil , just enough so that you can see some of the powdery spores wafting down and put the container near a window. Up close for a north facing window, back a foot or so for south facing window (reverse this in the Southern Hemisphere). 5) Wait. It will be 6-8 weeks until you see anything. Then you will see small flat leaflike plants, "prothallia" that will grow to about 3/8 inches across. If there are a lot growing close together they must be thinned out to about 1 or 2 per 3" area. If not they will only grow male organs. During this time make sure the potting soil in the container does not dry out.. You should check the soil every week or so. © Project SOUND
    • Nine Easy (if you are patient) Steps for Growing Ferns: 6) When the Prothallia get to 3/8" it will grow male and female organs. The male organ will make sperm which will swim to the female part and fertilize the egg. The egg will then grow into the fern plant that we see, called the "Sporophyte". During this time the prothallia should be sprinkled with water so that the sperm will be able to swim to the egg. 7) After another 6-8 weeks you will see little ferns come up; the first frond will be about 1/2" tall. Thin them out so they are about 3" apart. 8) In the spring give them a long time to adjust to the dry outside air by opening the top of your container a little bit each day. The open time should increase more and more for two weeks. If they look bad, close it up again until they recover, then try again. This is where I lose the most ferns; they have a hard time adjusting. 9) Plant them in a mostly shady spot, but not too shady. They are very fussy so keep an eye on them quite frequently for the first year. © Project SOUND
