Plant Collector: Tecomanthe venusta

The pink bells of Tecomanthe venusta

The pink bells of Tecomanthe venusta

We are so excited by our Tecomanthe venusta in bloom. That is because it is tropical but we are not so it doesn’t often flower for us. And I have to admit that there are only a few clusters of these pink flowers in evidence. A garden visitor once told us there was a specimen at the entry to Whangarei Gardens’ glasshouse which flowers magnificently. We have not seen it but it would figure that it is happier further north because it originates in New Guinea and is the most cold-sensitive member of the tecomanthe family, all evergreen climbers in the bignoniaceae group.

The tecomanthe family is not large and some readers will know our own T. speciosa – a tender but rampant climber which was found in the wild as a single, surviving specimen on Three Kings Islands. It needs a frost free position which rules it out for most inland locations and it needs a bit of training and management if you want to see the lovely creamy trumpet flowers. It will shoot up the highest tree available and flower only at the very top if left to its own devices, but if you train it along a horizontal support, it can be encouraged to flower along its length.

Back to T.venusta. We grow it under the cover of a deep verandah with opaque roofing. When it does decide to flower, it puts out clusters from its bare vines, which is very obliging because they are so obvious. Most plants set flowers on either new growth or last season’s growth but venusta appears to be quite happy to do it on gnarly old growth. We get a far more spectacular display in spring from the species we have as T. montana, also from New Guinea, which is grown in the same conditions but there is a delicious unpredictability to venusta.

Magnolia Apollo in summer

Magnolia Apollo in summer

Tikorangi Notes:

In days gone by, the Jury name used to be synonymous with camellias. These days it is magnolias and we can chart the year by repeated requests for diagnosis. In late winter and early spring, it is always: “Help. My magnolia buds look fine but then the flower opens all distorted and misshapen.” In this country, the answer is that a possum has developed a taste for the buds and chewed out the centre at an earlier stage. They can do this without it being obvious from below. The solution is to catch the critter – we favour high velocity lead, as Mark says.

In spring and summer, the question is: “Help. The leaves on my magnolia tree are opening all yellow, distorted and sick-looking on one side. What can I do?” The answer is that somebody has used a hormone spray – usually a common lawn spray – at the time when the tree is just breaking dormancy and there is nothing you can do except wait to see if the tree can recover. Oh, and be more careful next year (or ask your neighbour to) because the slightest hint of hormone spray drift at the wrong time does major damage. Don’t spray your lawn in spring if you have magnolias nearby.

Magnolia seed pod, not a sinister growth

Magnolia seed pod, not a sinister growth

This summer, we have had repeated requests for information about alleged abnormal growths and cankers which have appeared. SEED PODS, dear Reader. There is nothing sinister. The plant has set seed and you have just noticed it. Some plants set a fair amount of seed, some none at all (they are sterile) and some only set seed occasionally. And yes, you can grow them but the chances of getting something exciting and better than the parent are extremely remote. And you need space because it may take many, many years before the seedlings get to flowering size – by which time they can be large trees. When the pod eventually turns brown and dry, it starts to crack open and release the red seed. For better germination, we rot that red coating off before planting the inner black kernel.

Out of season summer flowers on magnolias are often mentioned too. There is nothing unusual about this phenomenon. I wrote about it in Magnolia Diary 14. It is in the breeding, basically. And they are bonus flowers, not a major display.

The Tikorangi weather report is better this week – some sunny, warm, summery weather at long last though the lower than average night temperatures and sunshine hours mean the water temperature in our swimming pool remains too low to entice us in. The pool is unheated and would normally be a pleasant 26 degrees celsius by now, maybe more but it is not even close. The only consolation is that the entire country is having a cooler than usual summer. It is always nice to know that one is not alone. At least the auratum lilies don’t mind and flower on beautifully.

Plant Collector: Ulmus elegantissima “Jacqueline Hillier”

Ulmus (should that be elegantissima, minor or x hollandica?) "Jacqueline Hillier"

Ulmus (should that be elegantissima, minor or x hollandica?) "Jacqueline Hillier"

It’s an elm but from there on there seems to be some debate. We received it under the species classification of elegantissima. The Hillier Manual of Trees and Shrubs lists it under the species name of minor with elegantissima added as a synonym. A quick net search and I see others now list it as Ulmus x hollandica which is a natural hybrid of minor and glabra. In other words, nobody knows for certain so we will stick with Hillier’s own classification.

The reason nobody knows for certain is that it was found in a garden in Birmingham in the early 1960s and it was visibly different. Most elms are renowned as handsome, large trees, though they have suffered hugely in the UK and Europe since the 1970s from a major outbreak of Dutch Elm disease which kills them. “Jacqueline Hillier” is smaller growing. In fact it came to us under the descriptor of dwarf. It has tiny, sawtooth leaves and very fine tracery of branch structure whereby the leaves are held in fan shapes. This means it is extremely attractive when it is a bare skeleton in winter. It is delightful when flushed with bright spring growth and it is lovely and lush in summer until the predations of the red spider sometimes defoliate it.

Dwarf it is not. I planted a specimen in our rockery where it set out to prove it belongs to the large shrub category. We have to keep working on it extensively every year to keep it down to about 3 metres x 3 metres. It also seeds and suckers but not in a dangerous way. Had I realised it would grow to that size, I would have planted it somewhere with more space – but I would definitely still have planted it.

Grow it yourself: spinach

Silver beet and spinach are close relatives. Indeed, somebody very close to me claims they taste the same when cooked, which I can’t argue against because it is so long since I have eaten the former. Texturally, I much prefer the finer, softer leaves of spinach and will happily eat those. Spinach is a winter vegetable. It will continue growing in colder temperatures but as soon as the weather warms in spring, it will bolt to seed. It is not quite as amenable as silver beet to grow and while you can leave plants in the ground and just pick as much as you need, it does not have the same cut and come again characteristics.

Well cultivated, well drained soil rich in nitrogenous fertiliser and full sun are the keys. Spinach is usually direct sown from seed and most of us now know to pick the thinnings and eat them as micro greens in salads or stir fries. The final spacing is in the 10cm range. In the right conditions, it is a quick crop because it will mature within a couple of months and you may have been eating immature leaves all that time. Some gardeners like to sow successive crops every few weeks to ensure continued supply.

There are a number of different spinach varieties, including New Zealand spinach or kokihi which is a different plant altogether (though similar taste and texture) and is our one great contribution to the global world of vegetables. While most spinach are spinacia, it is Tetragonia expansa. We recommend shunning the heirloom strawberry spinach (Chenopodium foliosum), being of the opinion that the reason it has been around for over 400 years is because it seeds so freely it is nigh on impossible to eradicate once you have it. The leaves are pleasant enough but the so-called strawberry seed heads are not.

Our pregnant gecko, Glenys, is back in view

Our pregnant gecko, Glenys, is back in view

Latest posts: Friday 3 February, 2012

1) The battle with the water weeds in Abbie’s column this week.

2) One for the dendrologists in Plant Collector this week – Pinus montezumae. It takes a bit to convince most New Zealanders that any pine tree is capable of being special but garden visitors do single our specimen of P.montezumae as being a tree out of the ordinary realm of the common pine.

3) Grow it yourself – silver beet. Some people are even alleged to enjoy eating this iron-rich but utility vegetable.

4) Welcome back Glenys, our highly prized but rather shy resident gecko. We are terribly excited by the evidence that we have a population of gecko in our garden, though that excitement does not appear to have been widely shared by others! But in this country, the small skinks are a common sight whereas our native gecko is nocturnal, elusive and rarely seen.

5) Check out the lily photo album I am building on our Facebook garden page. If you feel inclined to “like” the whole Facebook page, it would be most gratifying. Our popularity on Facebook lags behind the visitor numbers to our websites, and even the subscribers. This may of course just indicate that gardeners are less inclined to use social networks.

The auratum lily season is late this year, but no less spectacular for its delay

The auratum lily season is late this year, but no less spectacular for its delay

Tikorangi Notes: Friday 3 February, 2012

Oh summer, where art thou? Even the auratum lilies seem to be waiting for some real summer heat before opening fully in all their glory. This may go down in history as one of the coolest summers in recent history. On the bright side, the garden is very lush and green and working conditions are not unpleasantly hot. In fact, for Lloyd and I cleaning out the ponds and stream in our park, working conditions have been very pleasant. I just like a little searing heat to justify the fact we have a swimming pool. It has had precious little use so far this year.

Mark is very excited to see the blandfordia coming into flower. I have tried to photograph it but even by our standards, it is still looking a little too modest to boast about. It may look more notable when additional buds open. The reason for our excitement is that it was planted in the rockery by Felix Jury and as Felix died in 1997, it means it has been there for quite a long time and not doing very much. In fact, in all those years, it has only flowered twice before. Its third flowering is cause to celebrate.
