Product description
Delphinium Blue Bird is the quintessential, iconic blue border giant that gardeners actively seek out for classic structural height. It forms a sturdy clumping base before firing 1.8-metre spikes into the air, completely smothered in classic, clear mid-blue flowers that are brilliantly contrasted by crisp white central bees.
To keep it alive, you must plant it in deep, friable loam and maintain a strict, even watering schedule so the massive root system never completely dries out. You absolutely must provide heavy-duty structural support rings or bamboo canes before the heavy flower heads open, or a single rainstorm will snap them in half.
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
Tie the individual stems of Delphinium Blue Bird loosely to bamboo canes with soft twine as they grow to guarantee the classic mid-blue flowers stay perfectly upright.
How to Water
Keep the ground reliably moist, acting as a steady, ongoing hydration source for the towering floral spikes of Delphinium Blue Bird. You must never allow the earth to bake into a dry, solid brick, or the plant will simply stop growing. Consistently direct the water strictly at the soil line to maintain pristine, disease-free foliage.
How to Plant
Prepare a highly cultivated planting hole enriched with well-rotted organic matter to feed Delphinium Blue Bird. Position it carefully in a sun-trap that offers solid structural protection against sudden gusts of wind. Plant it firmly, ensuring the top of the root ball sits perfectly level with the surrounding topsoil.
