New Roses 1932.  Fireball (Dwf. Poly. G. de Ruyter 1930)  A glowing mixture of reddish orange. When seen at a distance it looks like a flame colour. Dark green glossy foliage. When planted outside it is rather freaky as to changing colour, but a bed of this gives them often a wonderful colour effect. 2/- each.
The colour is bright fiery red. There are so many similar that drastic testing is necessary. 'Fireglow' appears better to us as it seems even more fiery.
