1. Benefits of Citronella Plants:

   • Easy to Grow: These plants thrive in full sun and well-drained soil, making them suitable for both indoor and outdoor gardens.
   • Healthier Air: Like other plants, they contribute to better air quality by absorbing carbon dioxide and releasing oxygen.
2. Disadvantages:
   • Sensitive to Cold: Citronella plants are frost-sensitive. Protect them during colder months.
   • Not Edible: Despite the citrus scent, they are not edible like true citronella (Cymbopogon nardus) used in essential oils.
3. Propagation:
   • Stem Cuttings: Propagate by taking stem cuttings from mature plants.
   • Root Division: Divide established plants during repotting.
4. Repotting:
   • When: Repot every 2-3 years or when roots outgrow the pot.

Delphinium flowers

Delphiniums are a delightful group of plants known for their tall, showy flower spikes. Here’s what you need to know about growing and caring for these stunning blooms:

1. Varieties and Colors:
   • Delphiniums come in various shades, including true blue, purple, lavender, pink, white (such as Delphinium elatum), scarlet (Delphinium cardinale), and yellow (Delphinium luteum).
   • The central smaller flowers, often called “bees” or “eyes,” can appear in white, brown, tan, black, or striped patterns.
2. Growing Conditions:

   • Soil: Well-draining loamy soil with a slightly acidic pH (6.5-7.0) yields the best results. Add compost at planting time for these heavy feeders.
