Grasses and things

Grasses Chinochloa flavicans One of my first tasks at Dean's Nursery was pricking out grasses.  Chinochloas, Carexes, Sedges, Festuca, Poa.... I did not know how many different grasses there was until then. To give you an idea:  Chinochloa rubra (Red Tussock), Chinochloa flavicans (ToeToe), Chinochloa cheesemanii and many more Carex testacea, Carex comans, Carex secta, Carex buchananii, Carex dispacea... well it would take me forever to list them as the genus has more than 2000 species!  Apparently there is even a study called  caricology. All grasses are Monocts and perennials and belong to the family  Cyperaceae also known as Segdes. Carex is considered a true Sedge.  New Zealands grasslands is mostly covered by tussocks. There are around 190 native grasses.  Next time you to the Tablelands try figure out which grasses are growing there.  Or look around gardens, as many grasses are loved and used by Landscapers.

Peat Moss

Let me introduce you to a medium that is used a lot in Horticulture. PEAT MOSS The dark brown organic matter known as Peat is a unique organic material with several benefits for any gardener or horticulturist.  To keep it very short and simple Peat is sterile, absorbent and prevents soil compaction. Peat Moss retains water much better than average soils. It can hold up to 20 times it's weight in water. In addition it aerates and improves drainage of heavier soils, allowing roots to grow and take up nutrients.   It also does not contain harmful pathogens or any weed seeds. Therefore Peat Moss makes a great seed starting medium and is often added to potting mixes  to improve the soil structure of the growing medium. So what is Peat Moss and where does it come from ? Peat moss is a non-renewable resource that takes several millennia  to form and grows less than a millimeter a year. It is formed out of the decomposed remains of sphagnum moss and other living things formi...

Pōhutukawa

            Pōhutukawa (Metrosideros excelsa) If you drive around Rocks Road or Atawhai you will see the crimson red flowers of the New Zealand Christmas Tree in full bloom at this time of year.  The  Pōhutukawas belongs to the myrtle family (Myrtaceae) the same as Feijoa or Eucalyptus for example. Unfortunately that makes them susceptible to myrtle rust which is a fungal disease.  It also belongs to the Metrosideros genus, which includes northern and southern Rātā .  The Trees are naturally found in the North Island of New Zealand along the coast lines where sometimes harsh conditions make it hard or impossible for other plants to thrive. The  Pōhutukawa leaves have a waxy coat that protects them. Not only that, but the flowers produce thousands of seeds that disperse by the slightest breeze and can survive up to a month in salt water and freezing environment.  Maoris have used the nectar of the flowers to treat sore...
