Popular Varieties of Clematis:
Clematis 'Jackmanii': One of the most popular varieties, known for its deep purple, star-shaped flowers. Blooms in summer and has a vigorous growth habit.
Clematis 'The President': Known for its rich purple flowers, this variety blooms in mid-summer and is a classic choice for gardeners.
Clematis 'Montana': A vigorous variety with light pink to white flowers. It blooms in late spring and is often used for covering fences or walls due to its rapid growth.
Evergreen Clematis Varieties: While most clematis species are deciduous, some varieties are evergreen or semi-evergreen, which makes them valuable in milder climates for year-round interest.
Clematis armandii: An evergreen clematis with glossy, dark green leaves and fragrant white flowers that bloom in early spring. It is a popular choice for covering trellises or fences in mild climates.
Native Texas Varieties:
Scarlet Clematis (aka Texas Clematis), Clematis drummondii (Old Man's Beard), and Clematis pitcheri (pitcher Clematis)
Notes: Clematis do not like to be transplanted, so try to plant it in its forever home. 'Jackmanii' is a good variety, blooming deep purple in the summer. 'Evergreen Clematis' is amazing, even if it doesn't bloom. It's a hard one to find and pricey if you do.
