Purple lovers far and wide - this is your perennial! Agapanthus Royal Velvet is a variety with dark purple flowers that are strikingly vibrant. While some other purple Agapanthus have a more blueish tone, Royal Velvet is purple through and through, from the buds before they open all the way to the trumpet-shaped blooms when they're fully open. These striking flowers are held on stems up to a meter tall, stemming from a mound of deciduous foliage composed of long, thin, deep green leaves below. This foliage will last from Spring through to Autumn, where at its full spread it can reach around half a meter, making this quite a dominant variety in a bed or a border. Agapanthus like this one will also work great in a pot, as when potted Agapanthus bear more flowers because their roots are more confined. Looking for a practical purpose for your plants? This variety will sustain wildlife as bees and other pollinators adore their nectar rich flowers. Aside from those helpful pollinators, Agapanthus are generally pest free - and disease free too, so you can spend less time worrying about accounting for pests and disease and more time appreciating their stunning colour!

Planting Conditions

Agapanthus should be planted in moist, well drained soil, as they don't like too much water to stick around near their roots. Chalk, clay, sand or loam based soils are best, and they will tolerate any soil pH without troubles. When potted, Agapanthus also produce more flowers, as they can perform better when their roots are confined. It's also important that they're planted in a spot that gets 6 to 8 hours of sunlight a day, as they need this to create their impressive displays.

Watering & Feeding

Agapanthus love being a little more on the dry side than most perennials, meaning they won't need watering as often as other plants in the garden. Because of this, they should also be planted in soil that drains well - and this watering can be performed once or twice a week. If you're wondering when they should be watered in their flowering season, check the top inch of soil, as if it's dry then they could do with a water. They should be fertilised with a fertiliser of a 1-2-1 ratio, mainly in Spring and Summer.

General Care

Agapanthus are low maintenance plants overall which makes them perfect for newer gardeners. They won't survive through a cold Winter outside and so will need protecting in a greenhouse throughout the months where frost is a risk. When you come to plant your Agapanthus, dig a hole twice the size of the pot, place the plant in and fill in the rest with compost. A roughly 3 inch layer of mulch should then be applied around the base of the plant, and then watered until the soil is saturated to make sure that the plant will establish in its new location well.
