This is an unusual Jacaranda obtusifolia ssp. rhombifolia with purple flowers. Now I have it planted at the Fruits and Flowers garden too. Hopefully, this hot weather would always trigger the onset of its flowering.
The second is a plant I have never seen before. It qualifies as a first for me. Known as Samyda pubescens (Family: Flacourtiaceace), it has interesting pink flowers that bloom along the topside of the branches. The leaves are velvety giving it the specific epithet "pubescens".
The final two species are the dwarf Arundina graminifolia and the Clerodendron calamitosum which were flowering so prettily recently. What a wonderful day!
