Planting & Care

Where to Plant

Sunlight: Give this perennial at least 6 to 8 hours of direct sunlight daily to ensure strong stems and vibrant blooms. If planted in too much shade, the stems may become weak and flop over, requiring staking.
Soil: Plant in rich, well-draining soil that stays consistently moist but never waterlogged. If you have heavy clay soil, amend it with compost or plant in a raised bed to improve drainage and prevent root rot.

Watering Requirements

Keep the soil consistently moist, especially during the first growing season and hot summer spells, as these plants do not tolerate drought well. A layer of organic mulch around the base helps retain moisture and keeps the roots cool. Inconsistent watering can lead to stunted growth and increases the risk of powdery mildew.

Pruning Tips

Remove spent flower spikes immediately after the first bloom fades, cutting back to the lateral flowering shoots to encourage a second flush of color later in the season. Once the foliage yellows and dies back in late fall, cut the entire plant down to the ground to keep the garden tidy and prevent pests from overwintering in the debris.

Fertilizer Needs

Delphiniums are heavy feeders, so apply a balanced, slow-release granular fertilizer or a thick layer of compost in early spring when new growth emerges. Avoid high-nitrogen fertilizers late in the summer, as this pushes soft, leafy growth that is susceptible to cold damage when winter arrives.

Understanding Our Container Sizes

At Nature Hills, our plants are sold in industry-standard nursery containers. You will notice we use the word "container" rather than "gallon." Container numbers follow a nursery trade size standard, not liquid volume. The number tells you the plant's size category and general maturity level. A larger container means a more established plant with a stronger root system.

Container Sizes

Quart

Plant age: 6 months to 1 year
Best for: Ground covers, perennials, ornamental grasses
What to expect: Our smallest and most affordable size. Well-suited for planting in multiples across a large area. Allow 1 to 2 seasons for full establishment.

#1 Container

Plant age: 1 to 2 years
Best for: Shrubs, perennials, smaller trees
What to expect: About the size of a large coffee can. A well-developed root system in a manageable size. Good value choice when you have time to let the plant grow into the space over a season or two.

#2 Container

Plant age: 2 to 3 years
Best for: Shrubs and trees where you want faster establishment
What to expect: A noticeable step up from a #1 in both plant size and root development. Good choice when you want visible presence without going to a larger size.

#3 Container

Plant age: 3 to 4 years
Best for: Most plants, most situations — flowering trees, shade trees, evergreen shrubs
What to expect: Our most popular size. Strong, developed root system. Plants in a #3 container make an immediate visual impact from day one. If you want a head start rather than waiting seasons for a plant to fill in, this is typically the right choice.

#5 Container and Larger

Plant age: 4 to 5+ years
Best for: Specimen plants, privacy screens, maximum instant impact
What to expect: Large, mature plants ready to make an immediate statement in your landscape. We also carry #7 and larger sizes for select varieties.

Why "Container" and Not "Gallon"?

Nursery container sizes follow an industry trade standard established for the nursery and horticulture industry. The number is a size designation, not a measurement of liquid volume. Actual soil volume varies by plant type, root mass, and growing medium. Using "container" is the accurate industry term. When you see #1, #2, or #3, think of it as the plant's size tier, not a gallon measurement.

Root Pouch Containers

Some Nature Hills plants arrive in a Root Pouch, a breathable fabric container made from 100% recycled materials. Root Pouches encourage denser root development through air pruning, which discourages root circling and promotes a stronger, more fibrous root ball at the time of planting.

There are two types. Knowing which one you have changes how you plant:

Degradable (brown or tan fabric): Plant the entire pouch directly in the ground. The fabric breaks down naturally in the soil over time.
Non-degradable (black or gray fabric): Remove the pouch before planting. Cut the bottom open with scissors, then peel the sides away. The fibrous root ball will hold its shape.

Not sure which type you have? Check the tag on your plant or contact us and we will confirm.

The Glitzy Delgenius™ Delphinium PP#32,993 (Delphinium 'ET DLP 17-10') is a dazzling new perennial that brings the drama in all the best ways. With electric violet-blue blossoms edged in white and with a white 'bee' in the center! and held on sturdy stems that don't flop, this reblooming hybrid stuns from late spring all the way into early fall. And yes—it's fragrant!

Also known as Perennial Larkspur, Glitzy holds a tight, upright form and grows only 12-24 inches tall, making it perfect for small gardens, tight spaces, or elegant edging. Each finely dissected, deeply lobed green leaf forms a tidy clump at the base, while the flower spikes rise like exclamation points from the middle.

Unlike older Delphiniums that need staking and babysitting, this one's stems are thick and strong—no flopping here, thank you very much! Developed for resilience and repeat blooms, the Delgenius™ series marries old-fashioned charm with modern muscle!

Care and Maintenance

Glitzy thrives in USDA growing zones 3-8 and can even tolerate a bit more heat and humidity than traditional Delphiniums. As a member of the Ranunculaceae family (that's the Buttercup gang!), this hybrid is a stellar example of what happens when Ma Nature meets clever breeders. Grow it in well-drained, fertile soil with good sun, and you'll be rolling out the floral red carpet in no time.

Glitzy Delgenius™ Delphinium is an herbaceous perennial, meaning it dies back to the ground each fall and returns better than ever in spring. With its strong hybrid genetics, it's lower maintenance than older varieties.

Planting Time: Best in spring or fall
Sun Needs: Full sun to part shade (needs 4-6 hours of direct light)
Soil Needs: Well-drained, fertile soil; dislikes heavy clay or soggy spots
Moisture Needs: Regular watering needs, especially in hot weather
Arborist Mulch: Apply a 3-4 inch layer to conserve moisture and regulate soil temps
Fertilization Needs: Light feeding in spring with a balanced fertilizer encourages lush growth and repeat blooms
Pruning Info: Deadhead spent blooms to encourage reblooming
Renewal Pruning: Cut back spent stems to the base after flowering flushes
Special Needs/Perks/Growing Tips and Tricks For Success:

Deer and rabbit-resistant
Handles moderate heat and humidity
