Top and bottom photos are both Pachystachys lutea. They grow vegetatively during the rainy season and flower abundantly this time of year, when rains are nowhere to be seen. I always cut these hedge to a foot high just before the start of the rainy season. This area is sloping, so they help prevent erosion here. Planted below the Pachystachys is the Pedilanthus tithymaloides which is shorter with more branching, with other branches creeping on the ground to further delay erosion.
Our Sansevieria trifasciata started with the yellow stripes at the edges of leaves. Eventually, this yellow stripe was gone reverting into the original greenish form. I realized that stolons produce true-to-type striped form, but leaves produce only the green form. Green forms multiply and grow faster than the stripe forms, so i guess eventually our hedges will be mostly that of green. They also flower year round most predominantly during the dry season. Blooms are slightly scented. I will eventually deliberately plant the striped ones and get rid of the green. I can relate very well to its common name as snake plant with how it looks, however i still searched why another name is 'mother-in-law's tongue'. It revealed that the name is because of its sharpness! Hmmm, are mother-in-laws' tongue sharp???
This is a tall hedge of golden Duranta repens, named so because of the golden leaves. It is very common as hedges along local roads in our municipality. This particular one is allowed to grow tall without much pruning, allowing the flowers to become this golden berries. The butterflies and bees love the flowers, but i haven't seen anyone eating the berries. It is a lovely sight too.
Our Hippeastrum puniceum has been growing in hedges within the yard. They are perennially on the ground, rain or shine, rainy or dry season. They lost dormancy at the start of the first heavy rains in May, however something happened to them this year that some bulbs bloomed without the rains. My plant physiology knowledge has been extremely challenged by this phenomenon. These variety normally produce tall flower canes of 1-2 ft at fool bloom. However, bulbs i sent to a friend in Malaysia produced very short canes but maintained the flower sizes. I am really perplexed as to what environmental conditions affected what hormones, to alter its reproductive physiology affecting morphological characteristics. This unusual observation might put my mind into a limbo, until this is explained. If anybody knows the explanation, i will be very appreciative if you enlighten me.
