Mardi Gras Yak Rhododendron

Rhododendron degronianum ssp yakushimanum 'Mardi Gras'

The Story

Plant Bio

Rhododendron 'yakushimanum' varieties are renowned for their compact, dome-shaped habit, weather-resistant constitution, and exceptional evergreen foliage. New leaves are often covered in a beautiful, fuzzy coating called indumentum.

'Mardi Gras' is a striking cultivar with flowers that open from deep pink buds into frilly, light pink trusses with a prominent yellow-green flare. The flowers gradually fade to a creamy white, creating a multi-toned effect on the plant.

Uses & Benefits:

'Mardi Gras' is a four-season shrub. It offers a beautiful spring flower show, handsome deep green foliage in summer, and a perfect, dense structure in winter. The fuzzy indumentum on new growth and leaf undersides adds a unique textural element.

Its compact, slow-growing nature makes it ideal for smaller landscapes, foundation plantings, and even large containers. 'Yak' rhododendrons are also more sun and heat tolerant than many other types, broadening their use.

The spring flowers provide a source of nectar for bees and other early-season pollinators. The dense evergreen foliage offers year-round shelter for small birds.

How to Grow

Choose a site with acidic, well-drained soil and protection from winter winds.
Dig a hole twice as wide as the root ball and just as deep.
Amend the backfill soil with compost and pine bark fines.
Plant high, with the top of the root ball 1-2 inches above soil level.
Water thoroughly to settle the soil.
Apply a layer of acidic mulch over the root zone.

Pro Tip

Deadheading spent flowers is crucial for 'Yak' rhododendrons; it directs energy into vegetative growth and next year's buds, not seed production.

Keep It Thriving

Care Guide

Do

Provide excellent drainage; this is critical for rhododendrons.
Mulch to keep the shallow roots cool and moist.
Deadhead religiously after flowering.
Protect from harsh afternoon sun in hotter climates.

Don't

Do not plant in heavy clay or alkaline soil.
Avoid deep planting; it will lead to root rot.
Don't fertilize late in the season, as it can force tender new growth.
Never let the root ball dry out completely.
