Asplenium scolopendrium or Hart's Tongue Fern

Asplenium scolopendrium or Hart’s Tongue Fern

My friend Adam is a bit of a fern-aholic. He wants to know what to plant with them.

Ferns have this immensely ancient quality to them, a glimpse of the prehistoric, a promise of lurking dinosaur. They are cool and calm and beautiful. I love the way the fronds push up and quietly unfurl, without fuss or ceremony. But once uncurled they provide a marvellous backdrop for other flowering plants, or if planted en masse they can be quite arresting in their own architectural right. The Victorians were obsessed with them and displayed them in wardian cases – first constructed by Dr. Ward, a would-be botanist who, on finding that the noxious air was posioning his ferns in his London garden, decided to have these wooden and glass cases constructed to keep them in and in which they thrived.

Ferns are known as shade-loving plants but some will also take some direct sunlight – for example Polystichum setiferum – provided the soil is humus-rich and moist. They come in many sizes from the ground- hugging Asplenium trichomanes, growing to 20cm, an extremely useful native evergreen fern which will take the deep shade under trees, to the deciduous Osmunda regalia or Royal Fern, which reaches a stately 1.5 metres, particularly suited to waterside locations. Most ferns will thank you for giving them a good mulch of well-rotted manure or leaf mould prior to the growing season.

Below is a small selection of suggested plants to grow alongside ferns and which should thrive provided the conditions are right. Click on the image for an enlarged version.

    I drop a comment whenever I especially enjoy a article on a website or if I have something to contribute to the conversation. It’s
    a result of the passion communicated in the article
    I looked at. And on this article Friends for Ferns: for Adam | Tabitha Tarling Gardens.
    I was moved enough to post a thought 😛 I
    actually do have 2 questions for you if you do not mind.
    Could it be just me or does it look like some of the
    responses come across like coming from brain dead people?

    😛 And, if you are posting on additional places,
    I’d like to follow you. Could you list all of all your
    shared sites like your Facebook page, twitter feed, or linkedin profile?
