Named for the founder of the Holden Arboretum in Northern Ohio. Large open panicles with petals deep purple on the inside and silvery lavender on the reverse so when the wind blows, the color moves in waves; moderately fragrant. Foliage is dark green and very disease resistant (7').
A single flowered lilac of a special blue color. This nearly dwarf plant has mature height of 4 to 5'. Fr. Fiala wanted this plant called Little Boy Blue but the International Lilac Registrar denied the name. For years we have listed this plant as Little Boy Blue but in fact it was registered as 'Wonderblue'. Probably one of the best lilacs for a container.
