It is mainly the dry summers, rather than the winters, that have culled the material. In some places the weeds competed the azaleas out. The progenies from USA tend to acclimate too late in the season. Since 1993 the blooming has sometimes been profuse, sometimes negligible. In addition to flowers and floriferousness, attention is paid to the foliage and to the size and shape of the bush.
Azaleas can also display a marvellous bright autumn color.
Several dozens of candidates have been chosen. The majority of them will be cloned for testing in different hardiness zones in Finland, possibly also abroad. The best ones will then be released as new cultivars. The first cultivars will be plain yellows, oranges and pinks. Red and white colors were found in the 1992 crosses.
