Wildflower Characteristics

Why Plant Yellow Lupine?

Yellow Lupine combines true California native value, distinctive lupine structure and vivid yellow flowering in an annual wildflower.

N

California Native

A native annual lupine naturally suited to California wildflower and native-oriented landscape plantings.

Y

Bright Yellow Flowers

Upright flower spikes provide a strong yellow component that stands out among blue, purple, orange and white native wildflowers.

P

Pollinator Value

Lupine flowers provide useful floral resources for bees and other visiting pollinating insects during bloom.

L

Legume Function

As a member of the legume family, Yellow Lupine can form relationships with nitrogen-fixing soil bacteria when appropriately nodulated.

Where It Fits

Best Uses for Yellow Lupine

Yellow Lupine is particularly useful where California native value and a strong vertical yellow flowering component are desired.

California Native Wildflower Mixes Adds a native annual lupine with distinctive yellow flower spikes and palmate foliage.
Pollinator Plantings Provides spring flowers that contribute to the diversity of floral resources available to pollinating insects.
Meadow & Mass Plantings Upright yellow flowers provide strong visual contrast in larger native meadow-style displays.
Naturalized Native Landscapes Useful in open California landscapes where annual wildflowers are allowed to complete their natural growth and seed cycle.

Establishment & Management

Growing Yellow Lupine

Yellow Lupine performs best in open, sunny locations with good drainage and adequate moisture during germination and early establishment.

Sunlight

Full sun is preferred for strong plant development and abundant flowering.

Soil & Drainage

Choose a reasonably well-drained site. Avoid locations that remain persistently saturated during the active growing period.

Seed Establishment

Provide good seed-to-soil contact and adequate moisture during germination. Lupine seed has a relatively hard seed coat, so germination may occur over an extended period under field conditions.

Natural Reseeding

Where future volunteer plants are desired, allow seed pods to mature before mowing or removing the stand. Cutting plants before mature seed develops will reduce natural reseeding.

California Native

A Distinctive Yellow Lupine for California Wildflower Plantings

Yellow Lupine provides a different color and growth form than many familiar California annuals. Its bright yellow pea-like flowers are carried on upright spikes above palmately divided foliage, adding both vertical structure and strong color contrast to California native wildflower and pollinator plantings.
