About
Viola 'Blue Moon' is a compact, evergreen perennial that spreads modestly. It features dark green, oval leaves with serrated edges that develop a mottled appearance of green and golden yellow as they age. The plant produces fragrant, bi-coloured flowers; the lower petals are cream, while the upper ones showcase a blue hue accented by a darker purple stripe at the center and a dark yellow eye. These blooms emerge in spring and continue to flourish into autumn.
