FAQs
What is the best time to plant Lysimachia punctata ‘Alexander’?
The best time to plant is in spring or early autumn when the soil is moist and temperatures are moderate. This allows the plant to establish its roots before extreme weather conditions.
How much sun does Lysimachia punctata ‘Alexander’ need?
It prefers full sun to partial shade. In hotter climates, afternoon shade can be beneficial to prevent the soil from drying out too quickly.
Can this plant survive a UK winter?
Yes, Lysimachia punctata ‘Alexander’ is hardy in temperate climates, including the UK, and tolerates frost. It will return reliably each year.
What do you mean by 'marginal aquatic'?
Marginal aquatic plants are those that grow in shallow water at the edge of ponds, lakes, or streams. They have roots that can tolerate waterlogged soil or occasional submersion but do not typically grow in deep water.
How tall does Lysimachia punctata ‘Alexander’ grow?
It typically grows to a height of about 60-90 cm (2-3 feet), with its flower spikes contributing to its overall stature.
Is it difficult to control its spread?
While vigorous, its spread can be managed by regular division every few years or by planting it in containers or areas where its spread is naturally contained.
When do the flowers appear?
The bright yellow flowers typically appear in mid to late summer, offering a vibrant display for several weeks.
Troubleshooting
Plant is spreading too aggressively.
Divide the plant in early spring every 2-3 years. Remove and discard unwanted spreaders from the edges of the clump.
Foliage appears yellow or bleached.
This could indicate insufficient water. Ensure the soil remains consistently moist, especially during hot weather.
Plant is not flowering well.
Ensure the plant is receiving adequate sunlight (at least 4-6 hours daily) and sufficient moisture. Overcrowding can also reduce flowering; consider dividing the plant.
Leaves are damaged by pests.
While generally pest-resistant, slugs and snails may occasionally nibble on the leaves. Handpick pests or use appropriate slug deterrents.
Hardy and reliably perennial, returning each year.
Adaptable to moist soil conditions, ideal for challenging spots.
Adds structural upright form to garden designs.
Cons
Can have a vigorous spreading habit requiring management.
Prefers consistently moist soil, may struggle in very dry conditions.
Can appear somewhat informal if not managed in formal garden settings.
Seed heads are not particularly ornamental after flowering.
Setup, Compatibility & Care
Planting:
Choose a location with moist soil, full sun to partial shade.
Dig a hole twice the width of the root ball and plant at the same depth it was previously growing.
Water thoroughly after planting.
For container planting, use a large pot with drainage holes and a moisture-retentive compost.
Care:
Watering: Keep the soil consistently moist, especially during dry spells. Water deeply at the roots.
Soil: Prefers fertile, damp soil. Amend with compost if your soil is poor.
Pruning: Deadhead spent flowers if desired, though not strictly necessary. Cut back foliage in late autumn or early spring to make way for new growth.
Division: To manage its spreading habit and rejuvenate the plant, divide clumps every 2-3 years in early spring. Discard older, less vigorous sections and replant healthy divisions.
Compatibility:
Soil: Compatible with most garden soils, provided adequate moisture is present. Tolerates clay and loamy soils.
Companion Plants: Pairs well with other moisture-loving perennials such as Rodgersia, Ligularia, Hakonechloa, and various ferns.
Wildlife: Generally resistant to deer and rabbits. Its flowers are a magnet for bees and butterflies.
