Iris Penny Whistle

As showy as a peacock. Years of breeding, we have fallen in love with these fantastic new colour combinations that are sure to impress.

Exotic looking flowers are produced during the summer with intriguing markings that have inspired many botanical artists. Blousy blooms display from late spring over clumps of architectural strap shaped foliage. Excellent for naturalising, happy on the edge of a pond, and good for cutting. Easy to grow, preferring moist soil in sun or part shade. Height 60cm (24”). Spread 30-45cm (12-18”). Fully hardy perennials. Supplied as bare root plants.

"Thank you ladies for your beautiful plants.
Praise also, for the Bulrush Compost, of which I have purchased 8 bags during the past six months. It is superb and my garden has flourished.
Bless you,
Kind wishes"
