flowers are dark pink like ‘Evita’. Avalon’s flowers only stay open eight days, which is shorter than its progenitor ‘Evita’, which has flowers lasting 11–12 days. ‘Avalon’ is self- fertile with about 20% viability.
phylloclades have a diploid (2n) epidermis and a tetraploid (4n) sub-epidermis making 'Avalon' resistant to phylloclade drop and stem breakage. 'Avalon' is self- fertile with about 20% viability. These F1 seedlings resemble 'Avalon' as do the F2 seedlings.
