Product description
'Robert' is a fantastic, compact variety of Loosestrife that produces stiff, upright stems adorned with intense, vibrant pinkish-red starry flowers. It provides exceptional vertical structure and bright colour in the late summer border, whilst its willow-like foliage often turns attractive shades of red and orange before falling.
This perennial is a true moisture-lover, making it a perfect candidate for bog gardens, pond margins, or heavy clay soils where other plants might drown. It thrives in full sun, requires very little maintenance, and can be easily divided to create new plants when the clump becomes too large.
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.

Top Tip
With the Lythrum Robert, chop the flower spikes entirely down to the ground the moment the blooms fade to prevent it from dropping seeds, as it is a prolific self-seeder that can quickly become a nuisance.
How to Water
Lythrum loves moist to boggy soil. Keep the ground consistently wet, especially in full sun. They can even handle shallow standing water, so water frequently to ensure the soil never dries out completely.
How to Plant
Bury Lythrum in the heaviest, wettest, most clay-heavy dirt you can find, such as the margins of a pond or a naturally boggy dip in the landscape. It is exceptionally vigorous and will establish quickly as long as the ground is rich in organic matter.
