Golden Treasure Trumpet Vine

The Golden Treasure Trumpet Vine can grow up to 30-40 feet in height when supported by a sturdy structure, with a spread of around 5-10 feet. Its vigorous climbing habit allows it to cover large areas, such as fences, trellises, arbors, or walls. The vine’s size makes it ideal for creating privacy screens or adding a vertical element to landscapes. Regular pruning can help manage its growth and keep it within your desired space.

The Golden Treasure Trumpet Vine is a fast-growing plant, typically growing 3-10 feet per year under optimal conditions. With proper sunlight, watering, and support, it can quickly cover structures like fences, trellises, or walls. Its vigorous growth makes it an excellent choice for rapidly filling large spaces or creating privacy screens. However, regular pruning may be necessary to control its size and prevent it from becoming invasive.

The Golden Treasure Trumpet Vine (Campsis radicans ‘Golden Treasure’) is deciduous, meaning it will lose its leaves in the fall. During the winter, the vine will go dormant and shed its foliage, but it will regrow new leaves in the spring as it begins its new growth cycle.

Sunlight: The Golden Treasure Trumpet Vine thrives in full sun. Choose a location where it will receive at least 6-8 hours of direct sunlight daily for optimal flowering. While it can tolerate partial shade, the vine will produce fewer blooms in shaded areas.

Soil: Plant in well-drained soil. This vine can adapt to various soil types, including sandy, loamy, or clay soils, but it performs best in fertile, well-draining soil. Avoid areas with waterlogged or compacted soil.

Support Structure: The vine is a vigorous climber and will need a sturdy structure such as a fence, trellis, arbor, or wall to grow on. Make sure the structure can support its fast-growing, dense habit.

Space: Allow enough space for the vine to spread. It can grow up to 30-40 feet in height, so plant it in an area where it won’t crowd other plants or structures.

Climate: The Golden Treasure Trumpet Vine is hardy in USDA zones 4-9. It tolerates a wide range of temperatures and is both heat- and drought-tolerant once established, making it suitable for many climates.

The best location will provide full sun, good soil drainage, and enough room for the vine to climb and spread.

Planting Tips for Golden Treasure Trumpet Vine:

Location:
Choose a location with full sun, as this will encourage the best flowering. The vine can tolerate partial shade, but flowering may be reduced.

Soil:
Plant in well-drained soil. The Golden Treasure Trumpet Vine is adaptable to various soil types, including sandy, loamy, or clay soils, as long as the soil drains well.

Planting Depth:
Dig a hole twice as wide as the root ball and the same depth as the root ball. Place the plant in the hole, ensuring the top of the root ball is level with the soil surface, then backfill with soil.

Watering:
Water thoroughly after planting to settle the soil around the roots. Keep the soil consistently moist, but not waterlogged, during the first growing season to help the plant establish a strong root system.

Support Structure:
Provide a sturdy trellis, fence, or wall for the vine to climb, as it will need a support structure to grow on. If left without support, the vine may sprawl along the ground.

Spacing:
If planting multiple vines, space them 5-10 feet apart to allow for their vigorous growth and spreading habit.

Mulching:
Add mulch around the base of the plant to retain moisture and regulate soil temperature, keeping the mulch a few inches away from the stem to prevent rot.

Once established, the Golden Treasure Trumpet Vine requires little care and will grow vigorously, providing a beautiful display of yellow-golden flowers.

The Golden Treasure Trumpet Vine typically blooms from late spring through summer, usually starting in June and continuing until early fall, around September. The vibrant, trumpet-shaped flowers provide a long-lasting display, attracting pollinators throughout the growing season. In warmer climates, the bloom period may extend further into the fall.

It typically takes 3-5 years for the Trumpet Vine, including Campsis radicans ‘Golden Treasure’, to begin blooming after planting. The time to bloom can depend on factors such as growing conditions, care, and climate. Ensuring the plant receives full sunlight, proper watering, and well-drained soil can help encourage earlier blooming. Additionally, once the vine matures and becomes well-established, it will produce more abundant flowers each year.

Flower Size and Shape:
Campsis grandiflora (Chinese Trumpet Vine) produces larger, more bell-shaped flowers compared to the narrower trumpet-shaped blooms of Campsis radicans (including the ‘Golden Treasure’ variety).

Growth Habit:
Campsis grandiflora tends to be a more compact climber with a more controlled growth habit, growing up to 30 feet.
Campsis radicans is a more vigorous, fast-growing vine, often reaching 30-40 feet or more and spreading aggressively in some areas.

Flower Color:
Campsis grandiflora typically has orange to reddish flowers, while Campsis radicans varieties, such as ‘Golden Treasure,’ feature yellow to golden flowers, although the base species often has reddish-orange blooms.

Cold Tolerance:
Campsis radicans is generally more cold-hardy, thriving in USDA zones 4-9, while Campsis grandiflora is better suited for warmer climates in zones 6-9.


Both are attractive, flowering vines, but their differences in growth habit, cold tolerance, and flower characteristics help determine which is best for a specific garden or landscape.

Yes, the Golden Treasure Trumpet Vine is highly attractive to pollinators. Its bright, trumpet-shaped flowers are particularly appealing to hummingbirds, bees, and butterflies. The vine’s vibrant blooms provide a rich source of nectar, making it a great addition to gardens focused on supporting local pollinator populations.

For the Golden Treasure Trumpet Vine, use a balanced, slow-release fertilizer with an equal ratio of nitrogen, phosphorus, and potassium, such as a 10-10-10 or 20-20-20 formula. Apply the fertilizer in early spring to support vigorous growth and blooming. If needed, apply a second feeding in mid-summer. Organic options, such as compost or well-rotted manure, can also be used to enrich the soil. Avoid over-fertilizing, especially with high-nitrogen fertilizers, as this can result in excessive foliage growth at the expense of flowers.
