I always admire such weeds, such as Ficus, growing in crevices of walls and so on for their resilience and ability to overcome the harsh adversities of the site.
I also remembering salvaging some of these Ficus weeds and growing them in pots in my attempt to train them as bonsai plants. Well, that was all in the past.
On the other hand, my resident neighbours must have grown these medicinal and culinary herbs and plants, such as Plectranthus amboinicus, Pomegranate, Chili, in the neighbourhood garden. Frankly, I don't fancy edible garden plants because they are usually very boring to look at with its bland green leaves. That explains why I am still very weak in this area. The only such plant I appreciate is the Vinca rosea I posted earlier.
