Product description
Lysimachia atropurpurea, also known as Loosestrife, is a beautifully architectural perennial that brings tall, slender spires of deep burgundy flowers to the garden. Its elegant shape and rich colouring make it a standout choice for borders, plant beds, and mixed displays, adding height and movement throughout the summer months. The narrow, silvery-green foliage provides a lovely contrast to the dark blooms, giving the plant a refined look that suits both cottage gardens and more modern planting schemes.
This reliable plant grows well in well drained soil and will thrive in a sunny or lightly shaded spot. Water during dry spells to support steady growth and remove faded flower spikes to encourage fresh blooms. Loosestrife is naturally low maintenance and settles in quickly, bringing long lasting colour and structure to any outdoor space.
Please Note: When purchasing plants, please consider that each live item is unique and may therefore differ from the images shown, which are for illustration purposes only. The plant will be supplied in a growers pot. Depending on season, some plants may be pruned back to encourage growth and deciduous plants may arrive without leaves.
Garden Plant Size Guide

Plants in larger pots can be multiple years older than their smaller counterparts with more mature root systems and foliage. This makes them able to thrive as a full size plant in your garden quicker than smaller alternatives.
The most common size of pot that garden plants come in are 9cm/1L/3L/5L this is in reference to the diameter at the top of the pot.
9cm potted plants still remain the most popular cost effective option though, they just may take a little patience to allow them to grow into full maturity once planted in your garden.

Instructions
Top Tip
Leave a few seed heads on Loosestrife at the end of the season to encourage a gentle, natural self‑seeding effect. This allows the plant to sprinkle a few new seedlings around its base, creating a fuller, more natural look in the following year without becoming overwhelming.
How to Water
Water Lysimachia atropurpurea regularly during dry spells, keeping the soil lightly moist without becoming waterlogged. Once established, it only needs occasional watering, but steady moisture in early summer will help support strong growth and vibrant flower spikes.
How to Plant
Plant Lysimachia atropurpurea in well‑drained soil, setting it at the same depth as it was in its pot and spacing plants around 30-40cm apart. Firm the soil gently around the roots and water well after planting to help it settle in and establish.
