Lupinus nanus
Lupinus nanus, commonly known as Dwarf Lupine, is a low-growing, clump-forming perennial lupin. It's noted for its dense clusters of colorful flowers, typically in shades of blue, purple, pink, or white, that bloom in spring and summer. This variety is compact, making it ideal for smaller gardens or containers, adding a splash of vibrant color without needing extensive space.

Aphids

Aphids are small, sap-sucking insects that can infest lupines. Symptoms include yellowing or curling of leaves, and the presence of small, clustered insects on the leaves or stems. Infestations can lead to stunted growth and reduced flowering.

Slugs and Snails

Slugs and snails are common pests that can feed on the leaves and flowers of lupines. Symptoms include holes or missing portions of foliage and slime trails. They can severely damage plants if left unchecked.

Spider mites

Spider mites are tiny arachnids that suck plant juices. Symptoms often include stippling (fine speckling) or yellowing on the leaves, as well as the presence of fine webs on the plant.

Steps:

    • Sow seeds directly in the garden in spring, after the last frost.
    • Thin seedlings to 6-8 inches apart once they are established.
    • Provide consistent moisture but avoid overwatering.
