Which was precisely what happened to the neighbour’s Basella seeds; these dropped into cracks on our side of the wall and quickly took root in the shallow soil.
The seeds responded to the more favourable conditions and germinated readily. They grew upwards, and twined all over the neighbouring plants.
I rigged up a simple support using stakes and a nylon garden trellis, untangled the mess and trained the purplish Basella vines. The Basella now grows in some semblance of order and yields enough for a pot of soup every fortnight.
But despite feeding them regularly with fertilisers, our Basella can’t hold a candle to those sold in the market. The latter are such whoppers I suspect they’re on steroids. Sour grapes? Sigh … I guess you could say that.
Care and propagation: Partial shade to full sun, humus rich garden soil; water generously. Plant using seeds or stem cuttings.
