Not just green plants
Since the introduction of the series, new varieties have been added every other year. Currently, the series consists of 11 varieties of which the Black Coral is among the top selling varieties. This variety has deep black glossy foliage with blue veins and has a medium height of 48" x 36" at maturity.
New variety - Maui Sunrise
The latest introduction to the series is Maui Sunrise. Needam: "It is more compact than its sister plant White Lava and it has glossy green leaves with a white center that is expressed early in its growth. So it is still a small plant showing its white center when displayed in the garden center, attractive to the eye."
Maui Sunrise was firstly introduced at the Cultivate'18 in Ohio, Columbus, last month and the reactions were positive. "People liked the creamy white center which was larger than the normal Nancy’s Revenge type, and they liked the compactness and the fullness of the plant."
All over the US, the series is popular. "It is suitable for all areas in the US. For the cold areas, it is an annual item. It is hardy to Zone 7b (5F or -14C) and can come back the following year if mulched and doesn’t get too wet." And also in the UK and Europe, the program has been discovered and is being picked up. Currently, PlantHaven has two plug suppliers in the EU and slightly different varieties are being developed for this market. "The varieties for this market should be hardier, along with shorter, more compact and clumping, such as Maui Sunrise."
And Needham has high hopes for the existing series to take root in the EU as the weather seems to becoming hotter in Europe. "I think that more Colocasia varieties will become interesting for them."
