Mexican Shrimp and Golden Shrimp Plants

A small plant in the shape of bush caught my eye this summer, due to its peculiar orange colored flowers. Their petals form a scaly like body, which resemble shrimps even to the detail of their pop-out eyes.

Actually the common name of the Justicia Brandegeeana plant is "Shrimp" or "Mexican Shrimp". This also denotes that the plant is native to Mexico but has been exported to many distant countries with a warm climate.
The flowers come in small bunches of three to four buds.

The plant is growing up to 1 m (3 ft) tall in bushes with bright green and orange colors adding a nice note into any garden.

The Justicia Brandegeeana "Golden Shrimp" variety on the other hand has a deep yellow color with a little different positioning of the scale like petals.

When the dud is fully opened, white tongues emerge from within the yellow flower attracting the insects, mainly bees, for the process of pollination.

Although the height of this variety remains the same, the bright green foliage is larger and the buds sit individually instead of bunches.
