Lindera and the blue cohosh

,

Lindera benzoin, Northern spicebush, Forsythia of the wilds

Early in the spring (mid-April in some years) the flowering of Lindera, which grows as an understory, lightens up the deciduous woodlands. The small, abundant, bright yellow flowers are a sign of the long awaited spring and very useful to the early pollinators! The species it is also a favorite larval host for the beautiful Spicebush swallowtail and Promethea silkmoth.

Later in the fall, the foliage turns yellow providing a wonderful background for the shiny red, abundant fruits (female and male plants need to be grown together). They provide food for countless bird species.

The fleshy part of the fruits was/it is chopped and utilized as an allspice, hence the common name.

How many times I have written about Caulophyllum? One of my favourite wildflower because of the purple shoots that emerge in early spring and the beautiful foliage: a well grown plant of Caulophyllum can be easily taken for a peony. It is also an important medicinal plant.

The desire to grow it from seeds for my garden lead to an in depth study on its seeds and germination pattern. The seeds are hydrophilic to extreme! I repeat it, because people are still trying to grow it from dry seeds = dead seeds.

I will end with a picture taken last year in the garden. One more writing tomorrow and we’re done, spring is nearing and there are so many things to be done seedlings wise, before the purple beasties emerge :)

Purple beasties – Caulophyllum

,

Spring is evolving fast here in Ontario; Hepatica, Sanguinaria canadensis and Claytonia are flowering in our woods. Also, in some places blackish/purple beasties are erupting from the leaf mulch and growing with the speed of light – I am talking about the blue cohosh, Caulophyllum shoots :)

I wrote few times about Caulophyllum (referring in general to both C. thalictroides and C. giganteum) and its seeds, which are hydrophyllic and slow to germinate.
In this post I would like to bring to your attention two things:
The seeds offered up to this year were collected from a mix population of C. thalictroides and C. giganteum. Later in the season they are indistinguishable. C. giganteum is more desirable because has a deeper purple colour, purple flowers, and it gets taller. Depending on the luck, some may obtain C. giganteum seedlings.

This year the seeds of C, giganteum will be offered separate, from a localized population.

Caulophyllum giganteum, the shoots are coming up with the flower buds which open right away after few sunny days

Then, about germination: the seedlings are also appearing in my garden, and I can show two easy methods to germinate/grow it, without keeping around pots for 2-3 years until the seeds germinate.

  1. Sow the seeds into a compostable container buried into the ground (close to a large perennial, shrub) where you will water once in a while; cover with a mesh to discourage critters. A layer of leaves mulch can also be used in late fall, to mimic the natural environment.

2. Sow the large seeds directly into the garden, also close to a large perennial or shrub, where you know the soil won’t be disturbed. In my picture the seedlings are growing now among Polygonatum buds.

In a couple of years they can be dug up and planted at the desired place.

Stay tuned – Hepatica acutiloba and H. americana are in full flowering mode :)

What’s cooking?

,

My kitchen has become a small scale operation – thinking fruit pies, jams and jellies?

Caulophyllum thalictroides

Caulophyllum thalictroides seeds

Caulophyllum thalictroides (Blue cohosh) blue seeds will easily pass for blueberries but unfortunately are poisonous if ingested in large quantities. That’s very improbable to happen though because what seems like a big berry is actually a single huge seed surrounded by a thin fleshy and blue seed coat.

More likely to lose a tooth or two than being poisoned!

On the other hand, Podophyllum peltatum (Mayapple) fruit it is/has been used to prepare jams and jellies. The big size fruit (hog apple, wild lemon, Indian apple), when fully ripen has a light yellow colour and a persimmon fragrance (in my opinion). It is actually the only part of the plant that’s not toxic.

To ensure good germination seeds of both species have to be placed in moist storage right away. They belong to a large category of species with hydrophylic seeds (intolerant of dry storage).

Also, both species are important North American medicinal woodland plants.

PS. In case you have available large quantities of mayapple fruits to make jam, be kind and promote a sustainable harvest (always) by discarding the seeds in a nearby wooden area.
