Delphinium 'New Millennium Dwarf Mixed'

  • New in 2015
We source our delphinium stocks from the best breeder in the world to guarantee top performance from our plants in your garden. The towering flower spires that make delphiniums a must-have garden perennial, can require sturdy staking to prevent them flopping under wind and rain. We're looking to change that with Delphinium 'New Millennium Juniors Mixed'. The sturdy upright stems don't need any staking or support, but give the same cottage garden feel as traditional varieties. From the world famous breeding of Terry Dowdeswell in New Zealand, these shorter, sturdier plants have been bred to perfection, with clear colours, evenly spaced florets, long flowering and high disease resistance. Height: 75cm (30"). Spread: 60cm (24").
