Roses are one of the most popular flowers grown in home greenhouses With hundreds of rose varieties to choose from, it can be overwhelming deciding which ones to plant When selecting roses for a greenhouse, it’s important to consider factors like the rose type, size, fragrance, and growing requirements. By choosing a diverse mix of roses, you can create a stunning and fragrant display that blooms year-round.
Selecting Rose Types
There are several main categories of rose bushes that are commonly grown in greenhouses:
Hybrid Tea Roses
Hybrid teas are the classic rose with large, shapely blooms on long straight stems. They are ideal for cutting and arranging. Popular hybrid tea varieties include ‘Mister Lincoln’, ‘Double Delight’, and ‘Veterans Honor’.
Floribunda Roses
Floribundas produce dense clusters of smaller flowers on short stems. They bloom repeatedly over the season. Good floribunda choices include ‘Iceberg’, ‘Rainbow’s End’, and ‘Sexy Rexy’.
Grandiflora Roses
Grandifloras have the large hybrid tea-shaped blooms but with more flowers per stem. Some recommended grandiflora rose bushes are ‘Gold Medal’ ‘Queen Elizabeth’, and ‘Ch-Ching’.
Climbing and Rambler Roses
These roses produce long flexible canes that can be trained up supports Climbers generally have large flowers while ramblers have smaller flowers in large sprays. Try ‘Don Juan’, ‘New Dawn’, and ‘Zéphirine Drouhin’.
Miniature Roses
Miniature roses are dwarf bushes with tiny blooms. They are ideal for container growing. Some top miniature rose picks are ‘Cupcake’, ‘Rainbow’s End’, and ‘Magic Carrousel’.
Shrub and Landscape Roses
These tough, low maintenance roses work well in mixed borders. Go for hardy varieties like Knock Out®, Drift®, and Oso Easy® roses.
Consider Rose Size
Pay attention to the mature size of each rose variety. Miniatures and patio roses reach 1-3 feet tall and wide. Floribundas, grandifloras, hybrid teas, and shrub roses range from 3-6 feet tall and wide. Climbers and ramblers can grow 10 feet or more. Choose roses that will fit the space you have available in your greenhouse.
Select Fragrant Varieties
One of the joys of growing roses is their perfume. Be sure to include fragrant varieties like hybrid teas ‘Mister Lincoln’ and ‘Double Delight’, floribundas ‘Violet’s Pride’ and ‘Iceberg’, and climbers like ‘Zéphirine Drouhin’ and ‘New Dawn’.
Consider Growing Requirements
While all roses need full sun and well-draining soil, some varieties have particular requirements. For example, Old Garden Roses, many shrub roses, and hardy climbers are tough, low maintenance plants. On the other hand, hybrid tea roses, floribundas, and grandifloras perform best with more pampering. Provide them enriched soil, consistent moisture, and diligent disease prevention. Also check if the rose is grafted or own-root, as own-root roses adapt better to greenhouse conditions.
Choose a Diverse Mix
Planting a variety of rose types ensures you’ll have flowers blooming spring through fall. Aim for a mix of early, mid, and late season bloomers. Combine repeat bloomers like floribundas and shrub roses with just once-blooming types like hybrid teas and grandifloras. You can highlight different rose colors like red, pink, white, yellow, orange, lavender, and mixes. Having this diversity creates visual interest and provides cut flowers for arrangements.

Cut blooms in the morning when temperatures are coolest.

Remove foliage below the waterline which can rot.

Immediately put the stems in clean water. Recut 1⁄2 inch off the stems and change the water every few days.
