A plant that I have only just obtained from Plant Delights in the USA as A. thalictroides 'Argentine Lace'. They have now re-identified the species.
It has potential to be hardy in the UK, but it will be a couple of years before it is large enough for me to try. Unfortunately it didn't survive the rigours of the importation process. Plant Delights Nursery say: "(coll. #A1AG-276) (syn: A. thalictroides) Adiantum poiretii var. poiretii 'Argentine Lace' is a 2006 Plant Delights/JLBG introduction of a wonderful selection of the deciduous Meadow-rue maidenhair. This spore grown form hails from Tucuman Province, Argentina around 3500' elevation. The 2' tall, black arching stipes hold the pinnae, which are exceptionally small and dainty on this form. Since 2006, Adiantum poiretii var. poiretii 'Argentine Lace' has proven to be an exceptional clumping maidenhair fern in our woodland garden." Juniper Level Botanic Garden say: "Juniper Level Botanic Garden has an extensive hardy fern collection, and looking quite amazing for mid-January is Adiantum poiretii 'Argentine Lace'. This maidenhair fern was grown from our 2002 Argentine spore collection of a little-known and rarely-grown species, native to South America, South Africa, and the Arabian peninsula. It has thrived for us at JLBG since 2003. The dainty foliage is held atop shiny black stems that are several inches taller than the circumboreal Adiantum capillus-veneris. It will eventually become deciduous, but so far, night temperatures of 25 degrees F haven’t caused it to die back." |
