Fritillaria Raddeana (5 Seeds) a Rare and Unusual Fritillaria A rare and unusual species, smaller than, but similar in appearance to, the crown imperials. It's quite robust and fully hardy, and will delight you with its lovely pale creamy-yellow flowers, which are set off beautifully against the whorls of rich green leaves. Flowers April-May. Height 30cm. A stunningly beautiful plant with tall stems to 40cm topped with a crowded whorl of bright straw yellow, although some say lichen-green, flowers in March/April. With a striking resemblance to a "Crown Imperial Fritillary" this stately plant can take your breath away on first encounter. It grows well in sun or partial shade and is utterly reliable, increasing yearly in good soil.
