Blue Guardian Delphinium (Delphinium elatum ‘Guardian Blue’), also called Candle Larkspur, grows to majestic heights and sports stunning, richly colored, dark-blue florets with white center ‘bees’. Blue Guardian is a hardy perennial, growing in zones 4 - 7. Deep-blue blossoms make a lovely cut flower for floral arrangements or provide a tall, colorful display in your landscape.
This delphinium blooms from late May through early July; they put on a big show in early summer, and then give a second colorful show later in the summer. Bees love this plant; it also attracts butterflies, hummingbirds, and other important pollinators. Reaching heights from 30 - 40 inches and up to 36 inches wide, this perennial is lovely used in the midground of a cottage or English-style garden. As a bonus, it is also deer and rabbit resistant.
Blue Guardian Larkspur Care
Plant Blue Guardian Larkspur in full to partial sun in moist, nutrient-rich, well-draining soil. Select a spot in your garden that provides a bit of shelter to protect them from strong winds and harsh rains. Plant delphiniums so the crown rests slightly above the soil line to avoid crown rot.
Remove spent flower spikes to promote another flush of blooms in late summer. Blue Guardian is toxic to pets, so keep these blue beauties in an area your pets won’t roam.
Blue Guardian Larkspur Spacing
Blue Guardian Larkspur can spread up to 3 feet when happy, so give them plenty of room to grow. Plant them in mixed beds, cottage gardens, cut-flower beds, and pollinator gardens. Blue Guardian is fantastic as a cut flower in large floral arrangements; they also create a maximum color impact when planted in mass groupings.

Plant Addicts Warranty - 1 Year (Extra Purchase Required)
We encourage all plant lovers to purchase the Plant Addicts Warranty, whether you're a new gardener or an expert. There are many variables outside of anyone's control that can cause a plant to die. Hungry animals, drought, poor soil conditions, over watering, diseases & pests are all good examples of what can cause plants to die. The Plant Addicts Warranty is a 1 year warranty protecting you from all of the unknowns and will replace your plant if something were to happen to it.
The warranty is purchased on a per plant basis and must be purchased at the same time as the plant(s). We will cover 100% of the price of the plant, but the warranty does not cover shipping costs. SImply let us know if your plant has died within 1 year of receiving it and we will get you a new one shipped out as soon as possible (depending on the time of the year and availability). We may ask for photos for documentation purposes, but we try to make the process as easy as possible.

Plant Shipping
Below are some factors we consider when determining when to ship the plants depending on the timing of the order.
Winter to Early Spring
We ship only when it's warm enough to plant in your growing zone.
Sometimes plants aren't completely ready to sell and ship in early spring. We will wait until the plants are ready before shipping so you don't get a subpar product.
For Southern plants we will be able to ship much earlier than plants coming from our northern nursery.
Summer
If there is extreme heat we may delay shipping for a week or several weeks.
We review what areas the plants are traveling through as well as your location.
Fall into Winter
We’ll ship plants out all the way up to the end of the fall planting season!
Winter
Get your order in early to reserve your plants for Spring planting!
Once your plant is shipped you’ll receive an automated email with tracking information.
