Agastache ‘Royal Sceptre’
‘Royal Sceptre’ is a great new addition to our range of Agastache and to my mind a better plant than 'Blue Boa’ with stronger and less brittle stems. The 100cm or a little more tall stems proudly hold mauve-blue, bottle-brush flower heads. Best grown in full sun, ‘Royal Sceptre’ needs very little supplementary irrigation when once established. The nectar rich flowers, which are attractive to native honeyeaters, bees and butterflies, are produced from late spring until late autumn. 100cm tall by 70cm spread.
