Growing guide: Blue larkspur flower

 

The Blue Larkspur, or Delphinium elatum as it's scientifically known, is an absolute stunner in any garden. With its tall spires of blue blossoms reaching for the sky, it's sure to add a touch of elegance to your flower beds. If you're considering adding this beauty to your garden, let me guide you through the process of growing and caring for these majestic blooms.

Getting Started:

Blue Larkspur is a perennial plant, meaning it comes back year after year, and it thrives in temperate climates. Before diving into planting, here are a few things to keep in mind:

Location:

Choose a spot in your garden that receives full sun to partial shade. Blue Larkspur enjoys sunlight but also appreciates some relief from the intense midday rays, especially in hotter regions.

Soil:

Ensure your soil is well-drained and fertile. These beauties prefer soil that's rich in organic matter. If your soil lacks nutrients, consider amending it with compost before planting.

Planting:

Now that you've found the perfect spot and prepared your soil, it's time to get those Blue Larkspur seeds or plants into the ground.

Seeds:

  • If you're starting from seeds, sow them directly into the garden in early spring or late fall.
  • Scatter the seeds lightly over the soil surface and gently press them down. Don't bury them too deep; just a light covering of soil will do.
  • Keep the soil consistently moist until the seeds germinate, which usually takes around 14 to 21 days.

Transplanting:

  • If you opt for nursery-bought plants, transplant them into your garden in spring or fall, spacing them about 18 to 24 inches apart.
  • Dig a hole slightly larger than the plant's root ball, place the plant in the hole, and backfill with soil.
  • Water thoroughly after planting to help settle the soil around the roots.

Care:

Once your Blue Larkspur is happily settled in its new home, here's how to care for it to ensure it thrives:

Watering:

  • Keep the soil consistently moist but not waterlogged, especially during dry spells or in the heat of summer.
  • Water at the base of the plant to avoid wetting the foliage, which can invite diseases.

Mulching:

  • Apply a layer of mulch around the base of the plant to help retain moisture and suppress weeds. Organic mulches like shredded bark or compost work wonders.

Support:

  • Blue Larkspur can grow quite tall and may need support to prevent them from toppling over in windy conditions. Use stakes or cages to support the stems if needed.

Deadheading:

  • After the initial bloom, deadhead spent flowers to encourage the plant to produce more blooms and prolong the flowering period.

Pests and Diseases:

While Blue Larkspur isn't particularly prone to pests or diseases, keeping an eye out for common garden pests like aphids and caterpillars is always a good idea. Additionally, providing good air circulation around the plants can help prevent issues like powdery mildew.

Wrapping Up:

With its striking blue blooms and easygoing nature, Blue Larkspur is sure to become a favorite in your garden. Whether you're planting them in borders, cottage gardens, or as focal points, these majestic beauties will bring charm and allure to any landscape. So, roll up your sleeves, grab your gardening tools, and let's get growing!
