Iris Katharine\'s Collection  This special collection consists of two attractive varieties of Iris Reticulata that grow an abundance of delicate flower heads that can withhold the coldest weather to continue a striking display. For the most impactful and best results, plant this collection together in clumps beneath deciduous trees and shrubs, but they look equally eye-catching in rockeries, troughs and patio pots. Iris Katharine\'s Collection includes the following: 10 x Iris \'Katharine\'s Gold’ - Unique white variety, with elegant pale primrose yellow falls and indigo blue freckles. 15 x Iris \'Katharine Hodgkin\' - Intricately etched, pale blue-grey petals with the most intriguing patterns.
