The Cranberry Bog

In the spring I purchased one cranberry plant from a local nursery and kept it in the greenhouse over the summer.

It sprouted runners which I embedded in soil in smaller pots around the mother plant. I ended up with 13 pots with multiple new plants  per pot.

By the end of September, the mother plant had produced 3 berries and many extra plants.

I dug a small depression above my pond waterfalls, and lined it with old underlay and liner from the previous spillway of the pond.

I made the floor level by flooding it with water and then cutting down the high spots underneath.

The tractor bucket filled the depression with fertile soil and peat moss.

Azolla the floating fern – a Nitrogen fixer through a symbiotic relationship.

In August the bloom of Azolla has started to increase. I added Azolla to the pond several years ago and have in the past had to skim it off as it covers the complete surface in late summer. It does provide good compost material  with high Carbon and Nitrogen content.  It normally cannot live in Northern climates but somehow has survived well here in the pond.2015-08-06azolla2s

There is a theory called the “Azolla event ” where it is believed that Azolla in the tropical Arctic 39 million years ago fixed so much Carbon that it reversed global warming. Reference .

A good reference can be found at the Azolla Foundation

“Azolla is a unique plant that can help reduce man-made climate change and provide biofertilizer, livestock feed, food and renewable energy anywhere in the world.

The Azolla Foundation was set  up by Azolla Biosystems Ltd founders Alexandra and Jonathan Bujak to provide a platform for sharing information about Azolla and its contribution to new technologies such as space exploration and planetary colonization.”

Also, the Nitrogen Fixation is the result of a sysmbiotic relationship between azolla and a cyanobacteria. This reference shows the formula for the process:

Yellow Snowflake: Nymphoides geminata- pond plant

Last fall I got this small plant with floating leaves  and small yellow flowers. It spreads asexually with stolons near the water surface. It also was winter hardy Zone 8-10 as it overwintered in the pond.  This one was supplied to a plant store by a local company here in Victoria, Applied Aquatics.

Pond Lily identity a confusion-Schizostylis or Hesperantha ?

Schizostylis coccinea or Hesperantha coccinea

For several years now I have been growing a very successful and  attractive lily in the pond which I originally bought from a local plant store as a reddish-orange kaffir Lily,  Schizostylis coccinea. 

2015-july1pinkkaffirlily
Hesperantha coccinea a pink variety from the red-flowered parents.

The interesting thing is that it reproduces from seeds very well –and last year a pale pink variety came from a seedling. I kept these plants in the same pot and overwintered in the greenhouse. Normally the red flowers appear in August, but when I set it back in the pond in March, after continuing to bloom most of the winter, it flowered again for a month. Then in early June the pink-flowered plant came into bloom and is still flowering in July.   All the other “scarlet river lilies” (see political correctness comment below”)  that were left in the pond over winter will bloom again in late summer.

A number of interesting points come up when researching this plant:

2015-08-06pinklily copy
The pink version came out in bloom again in early August , 2015

1. The “pink” variety I have does not correspond to either of the pink varieties mentioned in this reference .  “Schizostylis coccinea ‘Mrs Hegarty’ was named by Sir Frederick Moore, the Director of Glasnevin Botanic Garden, after the lady who discovered a chance pink seedling in her garden in County Galway in 1914. She was persuaded to show her plant at the RHS show in London in 1919. It was immediately successful and was given an Award of Merit. Schizostylis coccinea ‘Mrs Hegarty’ has deep rose-pink flowers and yellow anthers and has been rather superceded by the cultivar ‘Sunrise’ which is also pink. Schizostylis coccinea ‘Viscountess Byng’ has pale pink petals and the anthers are purple brown. This cultivar is later flowering and is named after the dedicated rock gardener of the 1920’s. Her flower beds were sometimes temporarily covered in water.”
Reference: St. Andrews Botanic Garden Flower of the Month”However the anthers of the pink variety I have are pink!

2. A Scientific name change: Schizostylis  spp. came to be seen as distinct from Hesperantha  spp. whereas in almost every detail, Schizostylis is identical to Hesperantha. Most Hesperantha species have pink flowers, while Schizostylis is bright red. Since forms of Schizostylis with pink flowers are found in cultivation and in the wild, however, that doesn’t seem to count for much. The final proof is  that Schizostylis and Hesperantha is the DNA data, which confirms that the two genera cannot be separated.

3. Political Correctness has influenced the common name . For years it was known as the Kaffir Lily. As the Ken Thompson points out in this 2012 Telegraph article:
“–Kaffir is an offensive term for black South Africans. I suspect no one outside South Africa is likely to consider “kaffir lily” a racial slur, but nevertheless I sense a campaign is afoot to find something less offensive. Crimson flag lily, Cape lily and river lily, or scarlet river lily, all appear to be in circulation. ”
