My personal favorite primrose. This sieboldii selection blooms later than others but the flowers which are soft blue on the back of the flower and have a pure clean white face on the front. Heavily frilled petals are elegant on 8″ stems. Blooms May to early June in cooler years. No other cv of P. sieboldii comes as close to true blue. Forms a clump in time in rich, moisture retentive soil in part shade. Goes quickly summer dormant with true heat. Still water the roots of the dormant plant- they like that and will reward you with a greater show the following spring. Mix with Lamium maculatum ‘Aureum’ and Tiarella ‘Steam Punk’ for the same cultural conditions and a long spring to summer show. Great around the base of hardy Fuchsias as well. The leaves of the Primula disappear just as the Fuchsia is gaining steam. Excellent selection of this long lived spectacular Primula.
