This clematis pulls out all the stops and doesn’t bother being shy. Diamantina, a sport from breakout star Crystal Fountain Clematis delivers more fluffalicious petals and more blooms per stem than its sibling, yet the same amazing lilac blue color with pale yellow “fountain” center. It looks like a dahlia decided to start climbing. Considering there are two flushes of bloom, in early and late summer, and that individual flowers can last up to four weeks, that’s a near full-summer show! It attracts bees, butterflies, and hummingbirds but less so the deer and rabbits, which is nice. As far as pruning goes, this one is easy - a light spring shaping is all you need to do. Find a special spot for this stunner.
Diamantina extends a modest six to seven-feet tall, and up to two feet wide, so will make a beautiful vertical accent on a trellis, porch pillar, light pole, stakes, tuteur, or fence. It also makes a good cut flower, so you can enjoy the flowers inside and out.
Diamantina Clematis Care
Clematis like to have their “faces in the sun and their feet in the shade,” so choose a sunny location and mulch well. Garden Crossings recommends planting hybrids like Diamantina two inches lower than it was growing in the pot to guard against clematis wilt and keep the roots warm in winter. The soil should be kept evenly moist, but not wet. Take care to water well during hot weather, especially in the first two years in your garden. Clematis are twining plants, so it can be helpful to set up a narrow stake, length of twine or wire for them to get established on a larger structure at first. Flower color can vary by location.
A top-dressing of compost or aged cow manure in early spring should fuel those flowers, but if you would like to add more, you can apply some slow-release fertilizer once in spring, or liquid fertilizer once a month from April to July.
When it comes to pruning, the diverse clematis family is…complicated. There are three groups and you need to know which group your plant falls into. Lucky for you, Diamantina is Group 2 – a simple one! Because it blooms on both old and new wood, you don’t want to do any drastic pruning. Just trim back the plant by about a foot in early spring for shaping, as well as removing any dead or broken stems.
Diamantina Clematis Spacing
Diamantina spreads across only about two feet, which would be a perfect minimum spacing to allow air circulation.
