erbe e cappuccini .235

Nei vasi della mia casa crescono (in ordine di apparizione):

Quercus robur (piu' esemplari da ghiande del Parco Massari della mia citta' Ferrara)
Melissa officinalis (piu' esemplari)
Fragaria vesca (piu' esemplari)
Rosa spp. (piu' esemplari)
Sambucus nigra
Vinca major (piu' esemplari)
Rubus fruticosus
Acanthus spinosus (piu' esemplari)
Citrus limon
Nerine bowdenii
Berghenia eroica (piu' esemplari)
Nerium oleander
Mespilus germanica
Rhyncospermum jasminoides
Celtis australis
Zizifus jujuba 
Salvia officinalis
Crataegus monogyna
Taxus baccata
Clematis armandii (piu' esemplari)

  In questi giorni di inizio Giugno noto che i semi di graminacee germogliati tra le piante hanno uniformato il livello 00 del mio balcone in una sorta di prato.
Cos'e' avvenuto in questi anni?

  Qualche tempo fa avevo acquistato un sacchetto di semi di fiori selvatici dall'azienda SemeNostrumLi avevo piantati qui e la' nei vasi di casa (e pure sul tetto del vicino...) in manciate ricche di specie le piu' varie, ma con l'avvicinarsi della fine della scorta ogni manciata si riempiva di semi sempre meno variegati in quantita' dove la predominanza dei piu' piccoli e leggeri semi delle graminacee, fino ad allora rimasti nel fondo del sacchetto, andava a diffondersi con maggiore generosita' negli spazi loro assegnati dalla sorte tra le piante.

  Ecco come le erbe si sono diffuse facendosi strada piu' di ogni altra specie attraverso il misto per prato selvatico del sacchetto; le fioriture delle erbe, poi, hanno fanno il resto e questo inizio estate e' davvero frothy, come si dice per i giardini ricchi di vaporosa vegetazione... e per il cappuccino.

Ecological Planting Design

Ecological Planting Design

Drifts / Fillers (Matrix) / Natural Dispersion / Intermingling with accents/ Successional Planting / Self seeding
What do these words mean? Some principles of ecological planting design. (from the book: "A New Naturalism" by C. Heatherington, J. Sargeant, Packard Publishing, Chichester)
Selection of the right plants for the specific site.
Real structural plants marked down into the Planting Plan. The other plants put randomly into the matrix: No. of plants per msq of the grid, randomly intermingling (even tall plants). Succession through the year.
Complete perennial weed control.
High planting density. Close planting allows the plants to quickly form a covering to shade out weeds.
Use perennials and grasses creating planting specifications that can be placed almost randomly.
Matrix: layers (successional planting for seasonal interest) of vegetation that make up un intermingling (random-scattering) planting scheme: below the surface, the mat forming plants happy in semi-shade, and the layer of sun-loving perennials.
Plants are placed completely randomly: planting individual plants, groups of two, or grouping plants to give the impression of their having dispersed naturally. Even more with the use of individual emergent plants (singletons) that do not self-seed, dispersed through the planting.
An intricate matrix of small plants underscores simple combinations of larger perennials placed randomly in twos or threes giving the illusion of having seeded from a larger group.
The dispersion effect is maintained and enhanced by the natural rhythm of the grasses that give consistency to the design. They flow round the garden while the taller perennials form visual anchors.
Allow self-seeding (dynamism) using a competitive static plant to prevent self-seeders from taking over: Aruncus to control self-seeding Angelica.
Sustainable plant communities based on selection (plants chosen for their suitability to the soil conditions and matched for their competitiveness) and proportions (balance ephemeral plants with static forms and combinations such as clumpforming perennials that do not need dividing: 20% ephemeral, self-seeding plants, 80% static plants) of the different species, dependent on their flowering season (a smaller numbers of early-flowering perennials, from woodland edges, which will emerge to give a carpet of green in the spring and will be happy in semi-shade later in the year, followed by a larger proportion of the taller-growing perennials which keep their form and seed-heads into the autumn and the winter).
Year-round interest and a naturalistic intermingling of plant forms.
Ecological compatibility in terms of plants suitability to the site and plants competitive ability to mach each other.
Working with seed mixes and randomly planted mixtures.
Perennials laid out in clumps and Stipa tenuissima dotted in the gaps. Over the time the grass forms drifts around the more static perennials and shrublike planting while the verbascum and kniphofia disperse naturally throughout the steppe.
Accents: Select strong, long lasting vertical forms with a good winter seed-heads. Select plants that will not self-seed, unless a natural dispersion model is required.
Planes: if designing a monoculture or with a limited palette, more competitive plants may be selected to prevent seeding of other plants into the group.
Drifts: to create drifts of naturalistic planting that are static in their shape over time use not-naturalizing, not self-seeding, not running plants.
Create naturalistic blocks for the seeding plants to drift around. For the static forms select plants that do not allow the ephemerals to seed into them.
Blocks: use not-naturalizing species, in high densities, in large groups.
Select compatible plants of similar competitiveness to allow for high-density planting (to enable planting at high density in small gardens).
Achieve rhythm by repeating colours and forms over a large-scale planting.
