Tragopogon porrifolius L.

Deriva dal greco “tragòs” = “capra” e ” pogòn” = “barba“, anche denominata “barba di capra” riferito alla forma del frutto.
L’epiteto della specie si riferisce alla somiglianza delle sue foglie a quelle del porro selvatico.

Conosciuta anche come barba di becco o scorzobianca, barbabuc in piemontese, è una specie officinale e commestibile: ha proprietà diuretiche e depurative e si consuma lessa, in minestre o frittate. La sua radice, simile alla carota ma biancastra, è ricca di inulina il cui utilizzo come dolcificante è indicato nei diabetici.

Facile da coltivare nell’orto, seminandola in primavera o fine estate, il primo anno si possono raccolgiere le giovani foglie e le rosette basali, il secondo si raccolgono gli scapi florali.

Clematis vitalba L.

Conosciuta come Clematide comune, la Clematide vitalba appartine alla Fam. delle Ranunculacee, è una pianta perenne rampicante e vigorosa, con fusto a midollo pieno, lianoso, legnoso, che può raggiungere anche i 15 m di lunghezza, con la  caratteristica corteccia vibrosa e distaccata.

Il termine ‘Clematis’ ha origini greche: “klema -atos ” che significa “pezzo di legno flessibile, pianta sarmentosa,” in riferimento al suo  portamento  ,mentre ‘vitalba’ ha origini latine:  “vitis-alba“=”vite bianca”  che sta a sottolineare sia la somiglianza con la vite che la presenza di infiorescnze biancastre e infruttescenze argentee.

Le foglie sono opposte suddivise in 3 o 5 segmenti imparipennati, lanceolate od ovali ad apice acuto con margine intero o dentellato, provviste di peduncoli patenti ed ingrossati alla base e caduche.
Le infiorescenze sono raggruppate in pannocchie multiflore, laterali o terminali, provviste di un lungo peduncolo, poste all’ascella delle foglie con fiori a 4 o 5 sepali petaloidei biancastri, a forma di stella, vellutati su entrambe le facce, dal profumo intenso, con stami e carpelli numerosi.
I frutti sono piccoli acheni ovoidi, raggruppati all’estremità del peduncolo fiorale, porvvisti di una lunga appendice piumosa argentea. Il periodo di fioritura è maggio-luglio.

Si trova fino a 1300 m, in ambienti ricchi di siepi, muretti abbandonati, luoghi incolti, margine di fiumi e di canali  non presenta necessità particolari di terreno. Benchè oggi quasi scomparsa per la mancanza del suo habitat incolto ha una gran facilità a colonizzare l’ambiente e diventare invasiva e infestante.

Da non confondere con:

Clematis cirrhosa L. che ha le foglie sempreverdi e i fiori isolati penduli e giallognoli, con chiazze rosse.

Clematis recta L. – con il fusto eretto, in parte legnoso ed in parte erbaceo, non rampicante.

Clematis flammula L. con le dimensioni inferiori, le foglie bipennatosette e i petali biancastri con presnza di pubescenza solo sulla faccia esterna.

E’ una specie commestibile officinale. Contiene sostanze caustiche ed irritanti, tanto che i mendicanti la usavano per procurarsi volontariamente lesioni per impietosire i passanti: da qui il nome di ‘erba dei cenciosi’.

Le foglie fresche, ridotte in poltiglia e poi impiegate come cataplasmi erano un revulsivo, rubefacente e vescicatorio. L’infuso di foglie essicate era un diuretico, dai giovani germogli, cotti e lasciati in infusionesi otteneva un purgante.

I fusti secchi della pianta erano impiegati come sigari (smoking cane).

In cucina i giovani germogli (molto giovani in cui non si sono ancora concentrate le sostanze tossiche) venivano cotti e conditi con olio, sale e limone o fritti o aggiunti alle minestre.

In ogni caso come per tutte le Ranuncolacee se ne sconsiglia l’impiego sia officinale che commestibile.

Consolida maggiore.

Un’erbacea spontanea perenne dei nostri prati.

Scientificamente denominata Symphytum officinale.

 

DSCF0074

I suoi fiori sono particolari: penduli, rosa, viola, giallo biancastri, raramente bianchi sfumati di verde o avorio; in certe zone è esclusivo il colore giallo-biancastro o bianco.

 

DSCF0070

La forma e la pubescenza delle foglie le ha valso il nome colloquiale di orecchie d’asino.

DSCF0073

Porta il nome di “prodigiosa erba” atta a rinsaldare le ossa fratturate, e le sue proprietà medicinali sono conosciute da sempre, E’ astringente, emolliente, cicatrizzante, decongestionante, lenitiva, analgesica,vulneraria ed espettorante.
Se ne sconsiglia l’impiego interno a causa del contenuto in alcaloidi epatotossici, tipico di alcune Borraginacee.

Sei piante che allontano gli insetti dannosi.

Zanzare, pulci, zecche e moschini…. questo è il periodo dell’anno in cui intensificano gli attacchi, favoriti nel loro ciclo vitale da caldo e pioggia…..

Ma in natura esistono alcune piante che li tengono lontano, quindi perchè non cotivarle.

Tanacetum parthenium, Tanacetum cinerariifolium, Mentha pulegium, Lavandula angustifolia, Tagetes L. e Cymbopogon: sei piante belle, utili e di facile coltivazione.

Daucus carota sativa.

Non tutti lo sanno ma la nostra amata carota da sempre coltivata nell’orto e amica della vista e dell’abbronzatura deriva dalla Daucus carota ossia la carota selvatica che presenta anch’essa un fittone sviluppato ma molto legnoso e di colore bianco crema.

Per assurdo della pianta spontanea si impiega solo la parte aerea, cioè le foglie, molto profumate, come aromatizzante, analogamente ad altre ombrellifere come il Foeniculum vulgare (finocchio selvatico).

Capita che perà il gene di origine si ripresenti in quelche modo e tra tutti i semi messi nell’orto qualcuno sviluppi una carota un po’ differente, e al momento della raccolta si scopra questo:

Poco male. Si mangia comunque, sempre che non sia troppo legnosa e allora la si porta al cavallino.

Permaculture.

Frome ‘Permaculture magazine’  by Maddy Harland.

 

There are so many compelling reasons for growing even a little of your own food in the garden, on the patio, or even on the windowsill.

Take for instance the humble lettuce. On average of over 11 pesticides are sprayed on lettuces, more than any other vegetable crop. In one study pesticide applications had increased by 600% over a ten year period. Then those innocent bags of mixed salad from the supermarket are washed with chloride to prevent decay. This is hardly healthy eating for our children.

Food can contribute up to one third of your family’s carbon footprint – so buying locally produced food and growing your own is one of the greenest things you can do. It is also great fun and children love gardening.

Permaculture – Learning From Nature

As the old saying goes, ‘Nature is the best teacher’ and permaculture is based on observing natural systems, deriving principles to understand how they work and then applying to designing low carbon, green systems. These can be anything from a farm, woodland or community, but one of the best ways to demonstrate permaculture is in the garden. Here we can make connections, turn our waste into useful resources and create self-sustaining cyclical systems that work together healthily.

A typical example of a way of imitating nature in the permaculture garden is mulching the soil. In a woodland, nature rarely leaves the soil bare. Leaves form a moist covering to the soil and rot down, making a fertile dark loam full of beneficial micro-organism to feed saplings, established trees and shrubs and other flora and prevent nutrients being eroded away by wind and rain. In the garden we too can make leaf mould, compost and use cardboard, woodchip and straw to cover and feed the soil, establish rich loamy beds full of worms to turn the soil and make it fertile. Mulch also suppresses weeds.

Adding compost also creates healthy soil as well as being an important way of reducing household waste. Currently, the average household throws away 30lb of compostable waste.

Setting up a Permaculture Garden

The first task is to establish good composting systems as soon as possible. If you have room you can make your own composters from recycled pallets and add a mixture of kitchen waste (uncooked), grass cuttings and materials like shredded paper and spoilt straw to get the right mixture of nitrogen and carbon. You can also make a composter specifically for leaves and also one for ‘green brew’ – a DIY liquid organic fertilizer (often made using comfrey or nettle leaves and water). If you are limited for space proprietary composters (often at a reduced price from your municipality) and a worm bin for cooked food and vegetable scraps are very useful.

If you are starting from scratch select an area near your house for your veggie beds and composting area. The aphorism that the best fertilizer is the gardener’s shadow is so true. We all tend to live busy lives and so growing food near the kitchen door ensures that you can more easily pop out, pull a few weeds, sow some seeds and compost our waste. Make sure your beds are wide enough to reach in the middle but not too wide so that you have to stand on them to work which will compact the soil and cause water logging.

Define the edges of beds with long planks if you can but not bricks or stones in a damp climate as these are ideal habitats for slugs and snails. Planks clearly mark the paths – useful also for the children to know exactly where to tread – and allow you to build up the soil and make raised beds. These will be no-dig once you have removed all the weeds. The advantages of not digging but mulching and spot weeding instead are many. Soil is a living being with a delicate balance of micro-organisms that interact. Digging damages this living microcosm and destroys soil structure. Much better to leave ‘ploughing’ to the worms which turn the soil and aerate it. Don’t forget to add lots of well-rotted organic matter.

Next, select what to grow and order in your seeds. This is the fun part so be sure to involve the kids and choose vegetables and salads that they actually like to eat. There is no point growing food they don’t like! A strawberry bed is usually a must but remember you can also plant alpine strawberries anywhere in the garden as ground cover and children will enjoy foraging for their small but delicious fruits.

My children love vegetables like sweet corn, bush beans, parsnips, spinach, carrots, various varieties of beefsteak, bush and cherry tomatoes, fava beans and spaghetti and butternut squashes. These are always top of my list for space. I also like to plant as many varieties of ‘cut and come again’ and self seeding salads as possible such as mizuna, mibuna, oak leaf lettuces, land cress, arugula, and mache. Most seed catalogues have salad mixes that you can sow in one go so that you get variety for the price of just one packet – even a small salad bed can save a fortune on the weekly shopping bills and provide healthy greens from early spring to late fall. There is nothing as scrumptious as freshly picked greens and children love helping with the harvesting.

Of course, we prefer to buy organic seeds and also mainly choose varieties that are ‘heritage’ or at least not hybrids. F1 hybrid seeds may look nice but they are bred for a mass market and are not self-fertile so you can’t save their seed and germinate them next year. Heritage seeds are usually the older varieties that may not be popular in the supermarket (because they lack uniformity of size, shape or color or don’t store in refrigerated units well) but they are often more tasty, store well and produce good seeds for next year. They can be more robust against pests and diseases as well and by growing them you are supporting biodiversity in the garden.

My favorite spring job, besides getting out on crisp days and preparing the beds for sowing, is planting seeds inside. Children enjoy sowing pots and seed trays and watching them germinate in the warm. This is biology at home. My daughters never had any problem understanding hydro-, photo- or geo-tropism at school. They had learnt that plant growth is determined by moisture, light and gravity on the windowsill from an early age. All in all, growing plants is a wonderful way for a family to play and learn together and enjoy being outside.

“Growing what you eat has to be a good thing,” says my daughter Gail who is now 13. “You understand where food comes from and want to try new vegetables because you have grown them yourself. Who wouldn’t want to garden with their mom and dad? It’s such fun. You play outside and get your hands dirty!”
