    THE HARDY FERN FOUNDATION P.O. Box 3797 Federal Way, WA 98063-3797 Web site: www.hardyfernfoundation.org The Hardy Fern Foundation was founded in 1989 to establish a comprehen¬ sive collection of the world’s hardy ferns for display, testing, evaluation, public education and introduction to the gardening and horticultural community. Many rare and unusual species, hybrids and varieties are being propagated from spores and tested in selected environments for their different degrees of hardiness and ornamental garden value. The primary fern display and test garden is located at, and in conjunction with, The Rhododendron Species Botanical Garden at the Weyerhaeuser Corporate Headquarters, in Federal Way, Washington. Affiliate fern gardens are at the Bainbridge Island Library, Bainbridge Island, Washington; Bellevue Botanical Garden, Bellevue, Washington; Birmingham Botanical Gardens, Birmingham, Alabama; Coastal Maine Botanical Garden, Boothbay, Maine; Dallas Arboretum, Dallas, Texas; Denver Botanic Gardens, Denver, Colorado; Georgia Perimeter College Garden, Decatur, Georgia; Inniswood Metro Gardens, Columbus, Ohio; Lakewold, Tacoma, Washington; Lotusland, Santa Barbara, California; Rotary Gardens, Janesville, Wisconsin; Strybing Arboretum, San Francisco, California; University of California Berkeley Botanical Garden, Berkeley, California; and Whitehall Historic Home and Garden, Louisville, Kentucky. Hardy Fern Foundation members participate in a spore exchange, receive a quarterly newsletter and have first access to ferns as they are ready

  • (Polypodiales) Plastomes Reveals Two Hypervariable Regions Maria D
    Logacheva et al. BMC Plant Biology 2017, 17(Suppl 2):255 DOI 10.1186/s12870-017-1195-z RESEARCH Open Access Comparative analysis of inverted repeats of polypod fern (Polypodiales) plastomes reveals two hypervariable regions Maria D. Logacheva1, Anastasiya A. Krinitsina1, Maxim S. Belenikin1,2, Kamil Khafizov2,3, Evgenii A. Konorov1,4, Sergey V. Kuptsov1 and Anna S. Speranskaya1,3* From Belyaev Conference Novosibirsk, Russia. 07-10 August 2017 Abstract Background: Ferns are large and underexplored group of vascular plants (~ 11 thousands species). The genomic data available by now include low coverage nuclear genomes sequences and partial sequences of mitochondrial genomes for six species and several plastid genomes. Results: We characterized plastid genomes of three species of Dryopteris, which is one of the largest fern genera, using sequencing of chloroplast DNA enriched samples and performed comparative analysis with available plastomes of Polypodiales, the most species-rich group of ferns. We also sequenced the plastome of Adianthum hispidulum (Pteridaceae). Unexpectedly, we found high variability in the IR region, including duplication of rrn16 in D. blanfordii, complete loss of trnI-GAU in D. filix-mas, its pseudogenization due to the loss of an exon in D. blanfordii. Analysis of previously reported plastomes of Polypodiales demonstrated that Woodwardia unigemmata and Lepisorus clathratus have unusual insertions in the IR region. The sequence of these inserted regions has high similarity to several LSC fragments of ferns outside of Polypodiales and to spacer between tRNA-CGA and tRNA-TTT genes of mitochondrial genome of Asplenium nidus. We suggest that this reflects the ancient DNA transfer from mitochondrial to plastid genome occurred in a common ancestor of ferns.

Tracheophytes, also called vascular plants, possess lignified water-conducting tissue (xylem). Approximately 14,000 species of tracheophytes reproduce by releasing spores and do not make seeds. These are sometimes called seedless vascular plants. Tracheophytes differ from bryophytes in possessing branched sporophytes that are dominant in the life cycle. These sporophytes are more tolerant of life on dry land than those of bryophytes because water movement is controlled by strongly lignified vascular tissue, stomata, and an extensive cuticle. The gametophytes, however still require a seasonally wet habitat, and water outside the plant is essential for the movement of sperm from antheridia to archegonia. 2. The rhyniophytes were the first tracheophytes. They consisted of dichotomously branching axes, lacking roots and leaves. They are all extinct.

  • Cutting Back Ferns – the Art of Fern Maintenance Richie Steffen
    Cutting Back Ferns – The Art of Fern Maintenance Richie Steffen When I am speaking about ferns, I am often asked about cutting back ferns. All too frequently, and with little thought, I give the quick and easy answer to cut them back in late winter or early spring, except for the ones that don’t like that. This generally leads to the much more difficult question, “Which ones are those?” This exposes the difficulties of trying to apply one cultural practice to a complicated group of plants that link together a possible 12,000 species. There is no one size fits all rule of thumb. First of all, cutting back your ferns is purely for aesthetics. Ferns have managed for millions of years without being cut back by someone. This means that for ferns you may not be familiar with, it is fine to not cut them back and wait to see how they react to your growing conditions and climate. There are three factors to consider when cutting back ferns: 1. Is your fern evergreen, semi-evergreen, winter-green or deciduous? Deciduous ferns are relatively easy to decide whether to cut back – when they start to yellow and brown in the autumn, cut them to the ground. Some deciduous ferns have very thin fronds and finely divided foliage that may not even need to be cut back in the winter. A light layer of mulch may be enough to cover the old, withered fronds, and they can decay in place. Semi-evergreen types are also relatively easy to manage.
