FAQs

Please read our FAQs page to find out more.

Can I plant Pontederia in my pond now?

Plant Pontederia, also known as pickerel weed, in spring or early summer when water temperatures are rising. It establishes best in a sunny, sheltered pond margin or bog garden rather than deep water.

How deep should Pontederia be planted in a pond?

Grow Pontederia in an aquatic planting basket filled with fertile loam, with around 10 to 12cm of water above the soil level. Avoid placing a newly planted specimen too deep, as it needs time to establish.

Can Pontederia grow in ordinary garden soil?

No. Pontederia is a marginal aquatic plant and needs consistently wet soil or shallow water. It is ideal for pond edges, wetland areas and bog gardens, but will not thrive in a normal dry border.

When does Pontederia flower and how tall does it grow?

Pontederia produces upright spikes of blue flowers from late summer into early autumn. Depending on the type and conditions, it can reach around 60cm to 1.2m tall, creating a strong vertical feature at the pond edge.

Does Pontederia come back every year and will it spread?

Yes. Pontederia is perennial and dies back over winter before producing fresh growth in spring. It gradually forms a larger clump, so growing it in a planting basket makes it easier to control and divide in spring when needed.
