Montbretia ‘John Boots’ Overview

Botanical Description & Taxonomy

Crocosmia ‘John Boots’ is a cormous perennial in the Iridaceae family—that of the Iris.

Table with Comprehensive Plant Information

Ideal Applications

Ideal Applications: Crocosmia “John Boots” enjoys mixed perennial gardens, cottage gardens, and sunny garden edges. Its quite small scale also fits container gardening. It’s a great option to provide the landscape vertical interest and warm color.  

Ideal Growing Conditions for Crocosmia “John Boots”

Sunlight

Plant ‘John Boots’ Montbretia in full sun, requiring at least six hours of direct sunshine daily, for optimal flowering and vivid color. It can withstand some shade (four to six hours of sunlight), however flowering might be limited.

Soil

This plant so favors rather fertile, well-drained soil. To increase drainage, alter heavy clay soils with compost or another organic material. Perfect pH for soil is slightly acidic to neutral—6.0–7.0.  

Watering

Water often, particularly in the first growing season, to build a deep, broad root system. Once established, “John Boots” is rather drought-tolerant. Water deeply but less often so that the soil dries somewhat between waterings. Steer clear of overwatering if you want corm rot free.

Temperature and Humidity

Crocosmia “John Boots” does well in moderate humidity and warm temperatures. In USDA zones 6–9 it is hardy. In colder climates (Zone 5), think about including protection with winter mulch.  

Fertilizing

Fertilize “John Boots’ Montbretia in early spring, as fresh growth starts. Either use a liquid fertilizer diluted to half strength or a balanced, slow-release granular fertilizer. Steer clear of overfertilizing, which can cause too much leaf growth at the price of blooms.  

Crocosmia ‘John Boots’ Propagation Techniques

While growing Crocosmia from seed is less frequent for cultivars like ‘John Boots,’ as the offspring may not be true to type. If you want to attempt, plant seeds spring following the last frost.

Cutting propagation is not a practical way for crocosmia.

Division (Most Common and Reliable Method)

• Timing: Divide “John Boots’ Montbretia early spring or fall following flowering’s end.
• Digging: Carefully remove the whole corm cluster.
• Separately gently separate the corms such that every division has multiple healthy corms and roots.
• Replant the divisions 12 to 18 inches apart, exactly at the depth they were growing from before.

Not a usual way of proliferation for Crocosmia is layering.

Not relevant to Crocosmia is air layering.

Design concepts and accompanying plants

“John Boots’ Montbretia gives mixed perennial borders, cottage gardens, and cutting gardens a vivid burst of colour and vertical appeal. Its warm tones go wonderfully with other late-summer bloomers.

John Boots’ small scale makes them a great fit for container gardening. Plan with a well-draining potting mix and a pot with drainage holes.  

Accompanying Plants

• Salvia, Echinacea (Coneflower), Verbena bonariensis
• Yellow and Orange-flowering plants Rudbeckia (Black-Eyed Susan), Helenium (Sneezeweed), Hemerocallis (Daylily)
• Panicum virgatum (switchgrass), Miscanthus sinensis (maiden grass) for ornamental grasses  

Typical Issues and Remedies

Identity and Control of Pests

• Little bugs called spider mites can stipple and yellow leaves. Manage using horticultural oil or insecticidal soap. (University of California IPM – Spider Mites) (Source)  
• Thrips can produce deformed leaf development and silvering. Use insecticidal soap or neem oil to have control.

Treatment and Prevention of Diseases

• Caused by either poorly drained soil or overwatering, corm rot Verify excellent drainage and steer clear of overwatering.
• Rust: An orange or brown pustule-causing fungus that attacks foliage Eliminate sick leaves and increase air flow.

Typical Growing Problems

• Underwatering, overwatering, nutritional deficits, or pests can all lead to yellowing leaves. Find the fundamental reason and treat it properly.
• Nutrient shortages, little sunlight, or poor soil can all lead to stunted development.
• Lack of blossoms might result from late frost, inadequate sunlight, or crowding.

When To Purchase Crocosmia “John Boots”?

The ideal season for purchase of Crocosmia ‘John Boots’ is spring or fall.

Container plants vs. bare root

• Bare root is Purchasing bare-root corms in the fall helps them to establish roots before winter, therefore promoting earlier and more strong spring growth.
• Purchased and planted over the spring to fall growing season, container-grown plants provide additional flexibility.  
• Shopping for seeds Timing: If growing from seed, buy winter seeds to begin inside a few weeks before the final frost.
• Consider the climate of the region; spring planting of container-grown plants is usually advised in colder areas (Zone 6). Fall planting bare-root corms is best in warmer climates. Crocosmia “John Boots” is hardy in Zones 6–9.
• Gardening Goals: Buy flowering container-grown plants if you want instant impact. Buy bare-root corms in the fall if you want the best value and are looking ahead.
