More Information

Description ‘Diamonds Blue’ Delphinium (Delphinium grandiflorum) puts a twist on the classic English delphinium with shorter stalks and psychedelic flowers.  Elegant spires of electric blue blooms with splashes of purple steal the spotlight in the garden! The vibrant blooms are a beacon for pollinators, who will flock to your garden when flowering begins in summer. The spires are a must-have cut flower to keep your vases full! Plus, cutting the flowers will encourage wonderful repeat blooms later in the season. Other delphiniums have proven troublesome and challenging to grow. This new hybrid is adaptable and easier to grow. Don't fret over harsh winters because this perennial is resilient and hardy to cold climates. The shorter stalks reach only 18-23" tall and require no staking on your part! It's the perfect size and habit for use as a border, in masses, or containers.

So small

Super small for the price

Hello! Thank you for leaving a review. As mentioned on our website, we do ship young plants. The important thing when it comes to purchasing plants, whether online or in a garden center, is that they have a full, robust root system, and that's what we prioritize in our growing. The more roots a plant has, the more energy it can put into growing once it is planted in your garden. Happy Gardening!

Weak Plants

Pretty when first planted but very fragile, couldn’t even hold up to light watering with a hose. I jerry rigged some small stakes to support them and two out of four fowered, the others just kind of wilted and faded away. Praying that maybe next year they’ll come back hardier, I had such hope for these prett litlle plants and really wanted some delphis in my garden.

Hello! Thank you for leaving us feedback. It's hard to say for certain what could be happening with the new plants in your garden. When transplanting young plants from a nursery pot to a garden, the plant allocates more energy to root development instead of shoot development (above ground). It's important for them to develop a robust root system so they can actually absorb the nutrients and water in the soil around them. Then after their root system is more developed they'll invest in their shoots and flower development. We do have a 60-day guarantee on all of our plants. Our customer service team would be happy to further assist. Please email pictures of the plant to claims@greatgardenplants.com, making sure to put your order number and name in the subject line so that we may provide the best assistance possible. Happy Gardening!
