Garden Lore

“Once it has a toehold, incongruity has a way of advancing systematically through the garden like quackgrass.”

Garden Lore – weed plants

We bought a packet of seed of this pretty Commelina coelstris ‘Sleeping Beauty’ a few years ago and we have been working on eradicating it ever since. Mark decided it was dangerous as soon as he saw the seed set, even before we found that if you fail to remove all the tuberous roots, it can stage a comeback. It has such a pretty blue flower and we are fans of blue. Mind you, it is not as if it flowers in abundance like the common lobelias that seed down here and do no harm at all. I checked an American website and opinion was divided on the invasiveness of this plant but its ability to grow across a huge range of climatic zones, in every soil possible and in both sun and shade is a good indicator of weed potential in the hospitable conditions we have in this country. Pretty wildflowers in harsher climates can be an environmental curse here.

We haven’t complained to the seed company selling the commelina. Last time we mentioned to them about the weediness of a line they were selling (it was so-called strawberry spinach), the response we got was a dismissive: “Nobody else has had a problem with it”. The sub text to this might be: ‘we have no intention of stopping selling this plant and clearly you have no idea what you are talking about’. Since then, we have noticed others complaining about strawberry spinach. It took us years to eradicate it. It wasn’t even particularly appetising. Buy this, or the commelina at your peril. Campanulas are a better option for easy-care blue flowers.

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.
