FAQs

When is the best time to plant Lupin 'Legendary Blue Shades' plug plants?

It's best to pot up the jumbo plug plants upon arrival and plant them out into their final garden position after the risk of frost has passed in your area, typically from late spring onwards.

How tall do these lupins typically grow?

These lupins produce tall flower spires that can reach a considerable height, often 80-120cm (approx. 32-47 inches), depending on growing conditions.

Do I need to provide special soil for lupins?

Lupins prefer well-drained soil. While they appreciate moderately fertile soil, they do not perform well in waterlogged conditions. Amending heavy clay soil with grit or compost can improve drainage.

Can I grow these in pots?

Yes, lupins can be grown in large pots or containers, provided they have good drainage and sufficient space for their root systems. Ensure containers are adequately watered.

Are these lupins perennial?

Lupins are generally considered short-lived perennials. With good care and suitable conditions, they can persist for several years, though some gardeners treat them as biennials or re-sow regularly for continuous display.

Why are my lupin leaves turning yellow?

Yellowing leaves are often a sign of poor drainage or overwatering. Ensure the plant is not sitting in waterlogged soil. They prefer drier conditions once established.

Will planting these help my garden's ecosystem?

Absolutely. Lupin flowers are highly attractive to bees and butterflies, making them a valuable addition to wildlife-friendly gardens and supporting local pollinator populations.

Troubleshooting

Plants not flowering

Ensure plants are receiving adequate sunlight and are not over-fertilized. Check that the soil is well-drained. Remove spent flower stalks from previous seasons.

Yellowing leaves

This can indicate poor drainage or overwatering. Allow the soil to dry slightly between waterings and ensure the planting site has good drainage.

Damage from slugs/snails

Apply slug pellets or beer traps around the plants, especially when they are young. Barriers like copper tape can also be effective.

Weak or floppy stems

Provide support with stakes and ties before the stems become too tall and heavy, particularly in exposed or windy gardens.

Pros and Cons

  • Provides a classic cottage garden aesthetic.
  • Offers unique blue and violet flower colors.

Setup, Compatibility & Care

Setup:

  1. Potting Up: Gently remove the jumbo plug plants from their packaging. Pot them into larger pots (around 9-13cm) using good quality, well-drained compost. Water them lightly and allow them to establish in a bright, frost-free location.
  2. Planting Out: Once the risk of frost has passed and the plants have developed a strong root system, they can be planted into their final garden position. Ensure the soil is well-drained.

Compatibility:

  • Soil: Prefers well-drained, moderately fertile soil. Avoid waterlogged conditions.
  • Sunlight: Thrives in full sun to partial shade. More sun generally leads to better flowering.
  • Companions: Pairs well with plants like Delphiniums, Peonies, Hostas, and ornamental grasses. Avoid planting too close to plants that require very rich, moist soil.

Care:

  • Watering: Water regularly during dry periods, especially when establishing. Once established, they are reasonably drought-tolerant but perform best with consistent moisture.
  • Feeding: A light feeding with a balanced fertilizer in spring can be beneficial, but avoid over-fertilizing, which can lead to lush foliage at the expense of flowers.
  • Deadheading: Remove spent flower stalks to encourage a possible second flush of blooms and prevent self-seeding if not desired.
  • Support: Taller varieties may require staking, especially in windy locations, to prevent stems from snapping.
  • Pest Control: Monitor for slugs and snails, which can damage young plants. Use appropriate deterrents or barriers.
