About us

Since 1992 the Hibiscus Working Group – four renowned Hibiscus growers and the breeding company Agriom – has been jointly developing Sunny Cities varieties. The current range comprises around twenty varieties, all of which branch well, produce a lot of buds per branch, flower lavishly and for a long time, and have good keeping quality.

Our most recent selection programme focuses on the development of varieties that can be grown under more southern climate conditions for sale on the South European market. In this context we set up trial fields at the nursery of our group’s member Piante Keicher in Latina in Italy. Our efforts are resulting in a new line of Sunny Cities varieties, the first of which are Amalfi, Funchal, Lucca, Sabaudia and Sorrento.


Besides this climate-specific breeding work the Hibiscus Working Group makes constant efforts to develop varieties for normal, small and large pot sizes, and also standard Hibiscus trees.

Sunny Cities Hibiscus


Some of the specific characteristics of the Sunny Cities Hibiscus:

  • Little risk of bud drop
  • Perpetual flowering
  • Excellent branching
  • Good keeping quality
  • Lavish flowering

Grower-friendly varieties

Hibiscus plants need a lot of water, so they must be planted in soil with a high moisture-retention capacity whose structure won’t be adversely affected by large doses of water and will retain a sufficiently high air content. The heating temperature may be reduced for short periods of time. The pot temperature should be more or less the same as the heating temperature.


Hibiscus plants tolerate large amounts of light and also enjoy direct sunlight. Screening may be required only to adjust climate conditions. Fertilisation should be based on accurate measurements of the pH and EC during irrigation and should include extra doses of specific trace elements. Hibiscus plants may need extra growth regulation during their development, depending on the climate conditions.

Latina, November 2018 – Breeding company Agriom from De Kwakel selected 12 hibiscus varieties from the cloning trials at Piante Keicher in Italy for the Hibiscus Group at the end of November. After a second, extended test phase, part of the new varieties will become available to South European growers in 2020.

“They are all plants that excel in terms of plant structure, flower color, leaf shape and leaf color and are especially suitable for growing under more southern climate conditions,” says pot plant specialist Jan ten Brinke of Agriom. “For example, this one with those bright yellow flowers and a red heart, that shows very beautiful and he also has fabulous showy so-called ‘candles’,” he points to the erect flower buds . “And that plant there with that compact, shiny green leaves and apricot-colored flowers with a pink heart, that’s a flower color that we do not have yet. So it really complements our Sunny Cities assortment. ”

In total Ten Brinke and Dieter Keicher (see photo) selected twelve plants from the cloning trials. Dieter Keicher leads the company in Italian Latina where the cloning tests have been carried out for four years. Agriom, Piante Keicher and a number of renowned Dutch hibiscus growers together form the Hibiscus Group that brings the Sunny Cities line to the market.

For the next test, a few plants are added to the twelve selections from tests from a previous year. “Like Amalfi and Verona, for example,” Ten Brinke says. ,, These two were previously selected by the participating Dutch growers of the Hibiscus group and will be available to buyers at the auction in 2019.”


Agriom and the Hibiscus Working Group proudly present the first new selections from their climate-specific breeding programme for the Sunny Cities line. In trials at the Piante Keicher nursery in Latina in Italy, the varieties Funchal, Sorrento, Sabaudia, Première, Lucca, Torino and San Remo Improved were found to be the most promising for cultivation in the warmer climate of South Europe.

The trial fields in the south of Italy are supervised by Dieter Keicher. Agriom and the Dutch members of the Hibiscus Working Group paid him a visit in mid-October. Piante Keicher is also a member of the working group. Besides fully grown plants, Keicher supplies cuttings and half-grown plants of the new selection line to growers in South Europe.
