Queen's Diamond Jubilee: Plants to create a sense of occasion Coming down in scale, the lovely white water lily dahlia, 'Diamond Jubilee" (Crocus) is new this year, or consider Hosta 'Jubilee" (Bali-Hai Nursery), with cream and yellow-edged green leaves and lavender flowers; it would thrive in a container. Red Begonia Million Kisses Devotion ('Yadev") or Verbena 'Aztec Red Velvet." White Geranium 'Trend White," Bacopa 'Double White" or Osteospermum 'Serenity White." Blue Ageratum 'High Tide Blue" or Anagallis 'Skylover." All by mail order from Unwins. Catch them young If you're encouraging children and grandchildren to grow flowers, there's plenty of time to sow some quick-growing hardy annuals from seed. From Thompson & Morgan try Linum grandiflorum 'Rubrum" (red), Alyssum 'Snow Crystals" (white), and Phacelia 'Tropical Surf" (blue). The first flowers will appear in a few weeks. Or to be really cheeky, try 'Harlequin" carrots in red, white and blue from DT Brown. OK, they're orange, purple and cream - but close.
