What's New at Aroidia


The following lists detail the historical state of our work. We list current work as three stages: pollinated, fruiting, and germinating. Hybridization success here is measured by harvested ripe berries resulting in germinated seeds.

Verified berry set on a cross is indicated with berries. Harvested seed awaiting germination is shown by seeds. Once we have seedlings, the listing will include sdlgs. Crosses listed will remain until berries begin forming or until the inflorescence aborts. Once a cross is verified to have failed (aborted), it will be deleted unceremoniously from the list below.

Some crosses shown below were successful through the seedling stage, but unfortunate subsequent events caused the seedling(s) to be lost. Since the cross did yield viable seedlings, however, I have left the listing as a confirmation that the cross has been performed successfully.

The first plant listed in each pair below is the ovule parent and the second one is the pollen parent.

2011 Hybridization Work

We've started new work on Meconostigma Philodendron hybrids involving a new (for us) species, P. paludicolum and a series of crosses involving a hybrid of P. eichleri and an unusual P. bipinnatifidum clone from Robert Chumley. Our P. saxicola continues growing apace, but will not be mature enough for hybridizing this year, unless it blooms very near the end of 2011.

Another focus for this year's work is extensive Caladium hybridization, especially involving crosses between the Thai hybrids and Western hybrids. Not to be left out is our continuing work with the genus Alocasia, with which we hope to succeed at last in developing a black or dark-petioled plant with A. odora as one of the parents (for greater cold resistance).

2010 Hybridization Work

This year, we resumed development of new Meconostigma Philodendron hybrids. We have also just begun hybridization with the genus Typhonium. We hope to develop easy to grow plants with colors reminiscent of the early Caladium hybrids.

So far only one Alocasia hybrid cross has seemed to take, but it is a unique 4 species hybrid. Many of our 2009 and 2008 hybrid plants are not yet up to blooming size due to the exceptionally cold winter, so our plan to develop 5-species and 6-species Alocasia hybrids this year cannot be implemented yet.

We have completed a second series of successful crosses between the Western Caladium hybrids and the Thai Caladiums. So far we have germinated seeds using two different Thai varieties and two Western hybrids. One of the Western varieties is the Caladium "Red Flash" and the other is a hybrid developed at Aroidia.

2009 Hybridization Work

2009 was the year for complex hybrids involving 3 to 4 species. Already we have plants of several three-species hybrids, and are awaiting growth to maturity of a few hybrids involving four species. Additionally, we are completing work with A. watsoniana and both A. odora and our hybrid, Alocasia "Imperial Giant".

This year we also completed our first successful cross between a Western Caladium and a Thai Caladium.

The year 2010 holds promise for even more complex hybrids involving 5 or more species.

2005 Hybridization Results

Hybridization Work in Prior Years

Before Hurricane Andrew struck us in August 1992 (period 1980 to 1992), we had completed a number of crosses both with the genus Alocasia and the genus Philodendron. Among them were our legacy hybrids, the Calidora and Portora Alocasias. A number of years were spent in assembling the original research collection that was subsequently nearly destroyed by Hurricane Andrew.

During the years between Hurricane Andrew and the 2005 results above, new infrastructure and a new, expanded, research collection was built back to the point where our work could resume.
