The 1st plant is the Porphyrocoma pohliana (synonym: Justicia pohliana; common name: Rose Pine, South African Acanthus, Jade Magic, Purple Shrimp Plant, Maracas Brazilian Fireworks; Family: Acanthaceae) which I have seen a few years ago but did not gain popularity. I remember buying a pot of it back then but it died on me. I do find the leaves attractive with its silverish or white midrib and veins. 2 links are shown below:
Then there is the very attractive Justicia brandegeeana 'Fruit Cocktail' from the same Acanthaceae Family. Although less showy than the red bract Justicia brandegeeana, which I find very gorgeous, this is a newly acquired plant in our nursery since late last year or early this year, I think.

The next is the very beautiful Calathea ecuadoriana (common name: Red Zebrina Prayer Plant; Family: Marantaceae) which looks like a spitting image of the more common but equally handsome Calathea zebrina with a reddish leaf underside. The link is shown here:
The 4th plant is another Acanthaceae shrub known by the common name Rabbit's Ears, Hummingbird Plant or Monkey Face (scientific name: Ruttya fruticosa 'Yellow' or some refer to as 'Yellow Dragon'). The more common flower colour is orange but this particular variety has yellow flowers. 3 links are attached below:
The 6th plant is a naturalized Impatiens walleriana (common name: Busy Lizzy, Impatiens; Family: Balsaminaceae) where the petals are not of a single colour and are instead a mix of colours white and pink. Plant breeders take great pains to produce vibrant-one-colour cultivars of Impatiens but here we have an uncommon dual colour one which I found to be exotic, at least to me. The cultivars usually do not grow well outdoors in our hot and well tropical climate but I say this one is naturalized because I found it at the Queenstown area growing well in front of some shops. But look at the number of plants we have now. A link on the original species is attached below:
The final plant is an interesting cultivar of the Cordyline fruticosa (synonym: Cordyline terminalis; common name: Good Luck Plant, Palm Lily; Family: Liliaceae) with the leaves in an orangey, pink, green combination. 2 links are attached for reference:
