Achimenes or 'Hot water Plant'

Achimenes are a much hybridised genus often called the 'Hot Water Plant'. They get this from the theory that hey are best watered with water that has been allowed to get to a room temperatures, rather than the cold water from the tap.

They are a bulb or rhizome grown for their flowers which appear in summer. Achimenes are a sub tropical plant so require a degree of protection in cooler climates. Given this they may be aptly named hot water plants as cold water from the UK system may not be that great for them.

The trick to growing these lovely flowering plants in the UK is to keep the bulbs or rhizomes dry and frost free when dormant. In the UK these are an indoors plant, suited to warm position on an enclosed patio in a hanging basket.

One of the early hybrids still popular today is Achimenes ambroise verschaffelt. The flowers are white to pale lavender with lovely purple veins and a touch of orange to yellow in the throat, widely used in hanging baskets because of its excellent trailing habit this is one to look for as plant fairs and collectors meetings although still available commercially in season.

Achimenes grandiflora and Achimenes longiflora are the two most used species for hybridization.

Growing conditions and care
