Onoclea Sensitive Fern, Bead Fern, Sympathy Fern Native to North America, Canada and North Asia. Onoclea comes from the Greek onos, vessel, and klein, to close, referring to the pinnules of the fertile leaf, which roll up into bead-like segments to enclose the sori. A member of the Woodsiaceae Cliff Fern Family. Zone 4
Available in USA from ArcheWild Native Nurseries - Quakertown, PA Toadshade Wildflower Farm - Frenchtown, NJ Prairie Nursery - Westfield, WI Yellow Springs Farm Native Plant Nursery - Chester Springs , PA |
Upright, then arching, lance-shaped or triangular, pinnate, pale green sterile fronds. The bead-like appearance of the fertile fronds accounts for this genus's common name of bead fern. Some say that the name sensitive fern originates from the frond's sensitivity to frost (they wither after the first subfreezing temperatures). Winter survival will be enhanced if the dried fronds are left on the plant through the winter. |

Miscellaneous Ferns Hardy deciduous ferns. Fronds, barren ones, broad, once-divided, green; fertile ones, narrow, contracted, once-divided, brown. |
Suitable for Ferns for Acid Soils. Ferns suitable for Outdoor Containers Ferns for Wet Soils Cold-Hardy Ferns Shade-Tolerant Fern The fertile fronds are often used in dried flower arrangements. Best in wet woodland gardens and moist locations alongside streams and ponds. Can grow in very wet soils as long as there is adequate oxygen. It cannot tolerate sour clay or stagnant water. Also, does not tolerate freezing well, turns black even in light frost. Shelters salamanders and frogs |
Open swamps, thickets, marshes, or low woods, in sunny or shaded locations, often forming thick stands from sea level to elevations of 1500 metres. It grows best in a shaded or partially shaded area in a moist soil. The plant can tolerate dryer conditions in shade, and will tolerate wet soils and so occurs in soggy ground or at the very edge of water in shade or sun. Sensitive ferns spread to form colonies and are often the first species to inhabit disturbed areas. They can become weedy if not sited properly. |

Osmunda claytoniana Interrupted Fern, Flowering Fern Very hardy, Native to northeastern North America, India and Asia. The unusual common name for this fern arises because on the fertile fronds the fertile segments are carried in between sets of normal barren segments, giving the appearance of a gap in the frond. Young fronds are covered with wooly, pinkish hairs. |
The leaves grow from a rhizome growing at or below the ground. Forming a lovely spreading vase habit, this low-maintenance native fern makes a distinctive addition to the shade border or woodland garden. |

Polystichum acrostichoides Christmas Fern, Dagger Fern Very Hardy Species in Zone 3 |
Christmas fern grows in a circular form with all the leaves arising from a single point on the ground. It can form colonies but frequently grows singly or in twos or threes. The fronds grow from 30–80 cm long and 5–12 cm broad, divided into 20-35 pairs of leaflets or pinnae. Each pinna is typically 4 cm long and has a finely serrulate or spiny edge and is oblong to falcate in shape. |
12-18 x 12-18 Often used in Christmas floral arrangements because it is still attractive in December. It is a wonderful companion for spring blooming bulbs. Found in acidic to neutral soils on shaded slopes and well drained flats. The plant height varies from 1 to 2 feet (12-24 inches, 30-60 cms), and will gradually colonize an area even in poor soil. Christmas Fern is a top choice for gardens in Zones 3 through 9. |
Shield Ferns, Buckler Ferns, Holly Ferns and their Relatives The shield ferns of the genus Polystichum are small- to medium-sized terrestrial ferns commonly grown in temperate gardens. Many of the species are particularly attractive for their dark green, glossy, evergreen foliage. The plants are used in rock gardens, borders, or pots, and the larger species can be used as foundation plants or for background foliage. They are often slow to grow from spores. |
Ferns suitable for Border and Foundation Ferns Cold-hardy Fern Evergreen and Deciduous Ferns Shade-Tolerant Fern Cut Foliage Drought Tolerant in dry or moist shade Stove greenhouse and hardy ferns. Heights vary from 12-36 inches (30-90cms). |
Grow in well-drained soil, in shade it can tolerate dry conditions. Clump-forming. Grow in Part Shade and Full Shade. It is found in moist and shady habitats in woodlands, rocky slopes, and stream banks. The fern can conserve soil and allay erosion of steep slopes. The fronds are semi-erect until the first hard frost, after which they recline to be prostrate and effectively hold in place abscised foliage of the duff layer of the sylvan floor, which enables the gradual decomposition of the abscised foliage into humus, which in turn further conserves soil. |

Azolla caroliniana Hardy in Tropical - Subtropical Native to Eastern North America. Carolina - North America. Americas, Europe and Asia. Azollas tend to die in cold weather after forming buds, which sink to the bottom of the pond and resume growth when warm weather returns. Mosquito ferns prefer full sunlight, warm temperatures, and silty water containing organic matter. High light encourages reddish growth. Azolla is a highly productive plant. It doubles its biomass in 3–10 days, depending on conditions, and yield can reach 8–10 tonnes fresh matter/ha in Asian rice fields. Carolina mosquitofern distribution in USA.
This attractive floating pond plant will grow in damp soil or on moist rocks along the ponds edge. Usually covers 1 to 2 square feet (1 foot = 12 inches = 30 cms) of surface area. Pond Plants Online also provide Water Garden Planting and Care Instructions. |
Pale green, turning bright red in autumn (several weeks later they die and sink to the bottom), lacy-looking and closely overlapping. Plants are roughly circular to triangular and about the size of a dime.
Azolla has filamentous roots which extend down from the thread-like rhizome, which branches repeatedly and bears fronds in 2 rows. The nitrogen-fixing capability of Azolla has led to Azolla being widely used as a biofertiliser, especially in parts of southeast Asia. Indeed, the plant has been used to bolster agricultural productivity in China for over a thousand years. When rice paddies are flooded in the spring, they can be inoculated with Azolla, which then quickly multiplies to cover the water, suppressing weeds. The rotting plant material releases nitrogen to the rice plants, providing up to nine tonnes of protein per hectare per year. As the rice grows, the ferns are shaded, die and sink to the bottom, thus recycling the vital nutrient to the food crop. |
Less than 1 inch (2.5 cms) in height
Azolla caroliniana mature plant floats on the still water, and has no true roots, but the small divided leaves on the underside of the stem are often mistaken for them. The spores are found amongst these so-called roots. The plants grow annually from these spores. Frequently these are lost through insufficient care. They may be preserved by placing the plants in a tank of water that is half filled with sandy loam. When the plants die in the winter, the spores remain and germinate in the following year. They are very pretty plants, and hardly rise above the surface of the water which they cover with a carpet of green that becomes bronze in summer. |
Aquatic Ferns
Propagation: It propagates itself freely by division.
Water Garden Plants nursery is completely free from the invasive non-native species Crassula helmsii "The above Invasive non-native species can have a devastating cost to the economy, costing £1.7 billion to control. Floating pennywort, which can grow up to eight inches a day, costs the British economy £23.5 million per year. The plants form dense mats in water, depleting oxygen and light availability, causing declines in the numbers of fish and other aquatic species. They also reduce access to waterways for boating and angling and increase flood risk which, taken together, can cost millions of pounds per year." Press release Sale of invasive water plants banned to protect wildlife of Published 29 January 2013. |
Suitable for Aquatic Ferns. Hardy, Floating Aquatic Fern with delicate fern-like foliage.
They are great, attractive nutrient absorbers and the roots make excellent and attractive cover for fry. Cordon off a small area to place Azolla. How to grow Azolla caroliniana in aquariums. |
A free floating aquatic fern which forms colonies on still water. Easily grown in ponds etc, but very cold-sensitive. The common name - Mosquito Fern - is derived from the fern's supposed ability to discourage mosquito reproduction by densely carpeting the water's surface, thereby preventing the adults from laying eggs and preventing the larvae from getting air at the surface. This floating fern is the best species for growing on mud. |
