Hybrid Bee Delphinium

ZONE 3-7, HT 4-6', SUN/PART SUN
The strong spires on this New Zealand hybrid do not need staking while they support the dramatic, very dark purple flowers with white or brown bees.

Dwarf Delphinium

ZONE 3-7, HT 10-12", FULL/PT SUN Light pink flowers mingle gracefully over lacey dark green foliage from early summer until fall. This delphinium requires growing conditions similar to those of Delphinium 'Summer Blues'. Mix these two varieties in your perennial beds for a stunning show!
