IPHEION UNIFLORUM 'ROLPH FIEDLER'

Ipheion Uniflorum 'Rolph Fiedler' has won the Royal Horticultural Society (RHS) 'AGM' - the Award of Garden Merit (RHS link).  It's a little dazzler with its bold periwinkle-coloured face centred set against the rich green leaves.  I found it in the Alpine House of the RHS gardens, Harlow Carr, a week or so ago.  What interests me is the distinct line that divides each of the six petals on each flower.  It's quite wonderful.

According to the RHS, it's a bulb and the plant achieves a height of 10cm or 4in.  Unfortunately, it's half-hardy, H3, and needs winter protection in a greenhouse.  It likes full sun and well-drained soil and seems happy in any soil type.

I think if you are able to give this winter protection, it's certainly worth growing it.
