Description
‘Blue Spires’ is an upright, clump-forming perennial with lance-shaped, toothed, mid-green leaves and erect, branching stems bearing stiff, dense panicles of violet-blue flowers from early summer into autumn.
Verbena rigida and bonariensis are two of the toughest species, however one of the choicest species available is Verbena hastata, which produces masses of very small flowers on architectural flower heads.
Verbena hastata is a different plant from most commonly seen Verbena, Proving to be hardy through most winters in well-drained, sunny spots, its sheer volume of flowers make it a real winner. It is understandably increasing in popularity as it becomes more readily available.
Verbena hastata ‘Blue Spires’ is the blue form of this lovely perennial, with multi-branching candelabra-like flower heads, the flowers slowly expand as they ascend the stems like burning sparklers. The flowers appear in mid-late summer and will last into late autumn, especially if they are dead-headed when a second flush will appear.
Provides lots of mid to late summer colour in the garden. The plants look good when combined with ornamental grasses and other floaty plants in a mixed border or as part of a prairie planting scheme and make an excellent good cut flower.
Likes any moist but well drained soil in full sun.
Height 120cm x Spread 40cm
