Viola ‘Blackjack’ is a mesmerising viola with inky black, velveteen petals paired with a vividly contrasting white and yellow eye. These exquisite little charmers look fabulous planted in containers or drifting informally along the edge of a border where they shine out like little jewels. Height: 15cm (6in). Spread: 25cm (10in).
Culinary note - Some parts of these flowers are edible. Try the sweet tasting petals on top of salads or even pancakes, crystallise them for use as cake decorations too. For more details about edible flowers click here.
Garden Ready Plants - Our garden ready plants are selected for garden performance, straight from the nursery. We send them to you 'green' ahead of flowering (but please note some varieties may show a few blooms), which means plants will establish quickly and all their energy goes into producing better roots, so they produce more flowers throughout the season.

Thompson & Morgan strives to ensure that all its plants are delivered to you in the perfect condition for planting. While the majority of our nursery plants cope well with slight delays in intransit, sadly, the time it takes to deliver to certain locations in the UK means that we can't guarantee this for some of our smaller plug products and tender bedding and vegetable lines, which do not respond well to the extra journey time. So regretfully while we offer the majority of our live plant offering nationwide, we are unable to ship plugs, begging plants and tender vegetable plants to the following areas: HS, IV41-IV49, IV51, IV55-56, KW15-KW17, PA34, PA41-48, PA60-PA78, PA80, PH40-PH44, TR21-TR24, ZE1-ZE3
