Product description
Delphinium Atlantis is a Belladonna-type variety, meaning it naturally grows slightly shorter and significantly bushier than its towering cousins. It is highly prized for its intensely saturated, deep marine-blue flowers that sit loosely on branching stems above deeply divided, mid-green foliage, adding a brilliant hit of cool colour to the garden.
Give it a home in fertile, well-draining dirt bathed in full sun, and while shorter, it still requires consistent watering to support its rapid growth and heavy floral output. To maximise your investment, immediately cut the main stems back to the foliage line once the blue petals drop to force a secondary, later flush of blooms.
Please Note: When purchasing plants, please consider that each live item is unique and may therefore differ from the images shown, which are for illustration purposes only. The plant will be supplied in a growers pot. Depending on season, some plants may be pruned back to encourage growth and deciduous plants may arrive without leaves.
Garden Plant Size Guide

Plants in larger pots can be multiple years older than their smaller counterparts with more mature root systems and foliage. This makes them able to thrive as a full size plant in your garden quicker than smaller alternatives.
The most common size of pot that garden plants come in are 9cm/1L/3L/5L this is in reference to the diameter at the top of the pot.
9cm potted plants still remain the most popular cost effective option though, they just may take a little patience to allow them to grow into full maturity once planted in your garden.

Instructions
Top Tip
Cut the main flowering stem of Delphinium Atlantis down to the foliage line immediately after the blue petals drop to encourage a smaller, secondary flush of blooms.
How to Water
Deliver deep, soaking drinks directly to the root zone of Delphinium Atlantis to support its rapid development and intense blue flowers. It is incredibly thirsty while actively growing and will quickly drop its lower leaves if forced to endure a drought. Ensure the soil naturally drains away any excess water to protect the crown from rotting.
How to Plant
Plant Delphinium Atlantis in fertile, well-draining loam that gets bathed in sunlight. Settle the crown perfectly flush with the dirt and firm it in well to eliminate any hidden air pockets. Leave a comfortable gap around the base so the foliage is never suffocated by denser clumping neighbours.
