#FKA Hibiscus species

 Jacob Peter Storck (1836-1893)
Botanist and Nurseryman
Berthold Carl Seemann (1825-1871)
Botanist and Plant Hunter 
'Formerly known as' or 'name unresolved' applies to two interesting Hibiscus species which have an Australian connection and they are Hibiscus storckii and Hibiscus denisonii.
In 1859, German born Jacob Storck was working at the Botanic Gardens in Sydney where he met fellow German Berthold Seemann. The following year, on April 20th they set sail for Fiji on a plant hunting expedition where they discovered a pink flowered Hibiscus growing in the wild. Seemann named it Hibiscus storckii for his companion. Following this initial discovery it was never sighted again but later a Hibiscus which matched the description was found in Sydney and was named Hibiscus denisonii after Sir William Thomas Denison (1804-1871) who was a Governor of New South Wales from 1855-1861. Are they one of the same and where can I get my hands on one.? In the meantime they have been lumped together as just forms of Hibiscus rosa-sinensis.
The video below is an interesting retelling of some adventurous 19th Century garden and plant history.

Jasminum sambac 'Grand Duke of Tuscany'

 Jasminum sambac 'Grand Duke of Tuscany' (Oleaceae)
'Gardenia Jasmine'
How sweet it is...This is the Italian form of the Arabian jasmine which has button-hole perfect white flowers like mini Gardenias which become stained with purple on the outer petals as they age. The flowers are scattered through straggly angular stems embraced with quilted oval leaves and the resulting bush of a metre or more will never win a prize for being neat, clipped and tidy. It makes a good pot plant and table centre piece when in flower and growth is generally quite slow. The flower buds of the single form are used to make jasmine tea especially in the Philippines.
 I bought this one from the Growing Friends Nursery at the Royal Botanic Gardens in Sydney earlier last year.

Plectranthus 'Pygmy'

Plectranthus 'Pygmy' (Lamiaceae)
and when coping with light foot traffic.
A terrific hanging basket, ground cover or vertical garden plant, this Plectranthus ,which is probably a form of P.australis, has been available for a few years now and the only down side I have found to growing it is that it grows too fast, needing constant trimming back in a pot to keep it in check.
Pretty mauve and white flowers appear in autumn on the end of the trailing stems though it is the purple underside of the glossy leaves which are the real highlight. It will grow in full sun or deep shade and can spread a great distance to form a weed suppressing mat. Even if it strays across a path and gets trodden on it keeps on growing. It is a low water use plant and will tolerate some light frost but may need to be replaced in a pot when it 'exhausts' the growing medium as it exhibits tawny or cream leaves from fertilizer stress when this happens.
2017 update: I have stock in 140mm pots. 

Cadel's Day

Fernery at Geelong Botanic Gardens 1890's

Place to be today for the final event in the career of champion cyclist Cadel Evans, that is the Cadel Evans Great Ocean Road Race. Congrats to him on a stellar career.

Geelong Botanic Gardens is worth visiting for those with a passion for Salvias and Pelargoniums as the national collections of those plants are held there.

Hosta envy


I can't grow Japanese Hostas or the so called Plantain Lily. They like a cool climate, a shady location with humus rich moist soil and a vigilant protection from snails and slugs. That said I admired these in a plant trade market last week. That means they are available right now in retail Nurseries and Garden Centres

The village 'Crepe Myrtles'

 The Crepe Myrtle trees (Lagerstroemia indica) at the local shopping village have been flowering their heads off for weeks and I particularly like this red/dark pink one. The branches are being weighed down by the amount of flowers. A terrific small tree for gardens and parks.

black sugarcane, Saccharum officinarum var. purpureum

 Gomphrena 'Fireworks' flowering in front of black sugarcane
Saccharum officinarum var. purpureum (Poaceae)
The distinctive black stems and purple foliage of this ornamental and edible sugarcane make it an attractive addition to the summer garden particularly if planted alongside the large variegated Miscanthus 'Cosmopolitan' or some burgundy leaved orange flowering Canna 'Wyoming'. By the end of summer the stems may have reached 2 metres or more as it loves the heat and constant moisture, something we are getting plenty of if this afternoon's downpour is anything to go by. Large canes can be cut during the summer and used to propagate more plants by cutting the stem into short sections which include a node and laying them horizontally with a bare covering of soil. Having a few back-up plants is handy if you live in a frosty climate as they can be kept under shelter for planting out as the weather warms up.
 Growing an ornamental sugarcane plant provides a link to a part of the agricultural history of Australia while gaining an insight into some of the characters who were pioneers in the industry. While the sugar museum in Mourilyan, Queensland has recorded the oral history of the 20th century pioneers, some of whom were interned as 'enemy aliens' during both Wars, the 19th century records make for interesting reading while second guessing the motives and actions of those involved. Certainly this is the case with the 31 year old John Buhot who, with his wife Jessie, sailed into Brisbane on board the Montmorency in April 1862. He was born and raised in Barbados at the tail end of their sugar industry which was tainted with the dark side of slavery and he probably knew more than anyone in the Colony about establishing and nurturing the fledgling sugar industry here. Two months after his arrival his expertise in making granular sugar was put to the test with the help of engineer and architect Andrew Petrie (1798-1872) Twenty four canes were selected from the patch growing at the Brisbane city 'Botanic Reserve', yielding 7 gallons of juice and 5 pounds of sugar. The crushing of the canes and clarifying of the juice was carried out on the footpath of the Brookes and Foster Ironmongers establishment at 143 Queen Street. No doubt a crowd gathered to watch this process and with much fanfare the clarified liquor was taken back to the gardens for the final process of turning it into granular crystals. For his efforts he was promised a grant of 500 acres of land by a select Parliamentary Committee consisting of Messers. S.W. Griffith, Moreton, Buzzacott and Macrossan. This promise came to nothing though he was no doubt living comfortably by 1874 in his 56 acre Dunellan Estate in what is now the Brisbane suburb of Greenslopes. On his death at age fifty in 1881 his wife reminded the government of their promise but this was dismissed. His falling out with sugar industry associates such as Louis Hope from Ormiston indicates he may have been quite quick tempered or a just a victim of a 'tall poppy' syndrome frustrated by his efforts to get people to take notice of someone born with sugar 'flowing through his veins' from a young age. A hundred years after his initial 'manufacture' experiments, a plaque was unveiled to honour his achievements at the Brisbane City Botanic Garden, with his descendants in attendance. He is also remembered by a row of fig (Ficus) trees he planted in Quay Street Rockhampton and by Buhot street in Geebung.
