Yacon and Madeira Vine flowering outside

To my surprise, I noticed today that both yacon (Polymnia sonchifolia) and Madeira Vine (Anredera cordifolia) have managed to flower outside in the garden before I bring them inside for the winter just before the first frost. I’m surprised as the autumn has been colder than normal…maybe this is rather a consequence of the record warmth in June.

An alternative spring harvest

Somebody asked me the other day if I use floating mulch (fiberduk / agryl) to be able to harvest all these greens so early. No, no and again no….this is one of the biggest benefits of perennial vegetables….it is totally natural, no microplastics are released into the environment, no oil is needed to plough the fields, significantly less migrant labour is needed and little or no fertiliser and water is needed, it is almost totally free once established and can yield year after year! So, whilst large areas of farmland in the northern hemisphere are being covered by plastic mulches to bring on annual crops for the market earlier, I’d just like to point out that there’s an alternative better way!
So, here are the plants that I harvested for yesterday’s delicious green pasta sauce:
Armoracia rusticana shoots (horseradish / pepperrot)
Myrrhis odorata
(sweet cicely / spansk kjørvel)
Houttuynia cordata “Chinese Market” (shoots and rhizomes from the cellar; this cultivar is significantly larger than other Houttuynia I’ve grown) (Fish herb, Himalayan water creeper)
Allium senescens x nutans (hybrid Siberian onions)
Laurus nobilis (bay / laurbær)
Brassica oleracea (perennial kales)
Crambe maritima (sea kale / strandkål)
Taraxacum officinale (dandelion / løvetann)
Allium x proliferum (walking onion / luftløk)
Hablitzia tamnoides (Caucasian spinach / stjernemelde)
Dystaenia takesimana (giant Ulleung celery, seombadi)
Oenanthe javanica (seri)
Polymnia edulis (yacon) (second picture)
plus garlic and chili

Yacon

..and end of the year Yacon harvest

Yacon (Polymnia edulis/Smallanthus sonchifolius) also gives higher yields when grown on inside until the end of the year in a large pot; however, it is much less day length sensitive than ulluco and oca…when I had a cold greenhouse, yacon would give at least as good a yield as this by October…
The sweet tasting tubers are becoming quite popular in recent years! Yacon is in the Asteraceae, the roots containing inulin like its edible tubered cousins Jerusalem artichoke and Dahlia.

The yacon was moved into my living room which is heated…about 2/3 of the leaves froze off before harvest, but it resprouted from the base and continued flowering….

The propagules were sprouting (small nodules used to start next year’s plants)
