Pinguicula 'Weser'

Pinguicula 'Weser' key facts

Growing Difficulty

Beginner-friendly

Lifespan

Perennial (can be kept for years by division and leaf cuttings)

Size

Little published size data

Watering

Little or no fertilizer needed (catches small insects on sticky leaves)

Temperature & Overwintering

In summer it makes carnivorous leaves in warm, humid conditions; in winter keep it cooler and drier and it rests as a rosette of succulent leaves. Typical indoor windowsill conditions suit it well.

Light & Placement

Grow on a bright windowsill or under lights. Many grow on cliffs with little direct sun in the wild, so avoid harsh midsummer sun.

Watering

In summer, when it has carnivorous leaves, the pot can stand in up to 2 cm of water. Once it switches to succulent winter leaves, let it dry for about a week between waterings.

Soil & Repotting

It is not a bog plant; a mix of equal parts peat, coarse sand and perlite with dolomitic lime added to make it alkaline suits it. Repot or divide in the winter resting phase.

Propagation

Keep the cultivar true by leaf cuttings or division; plants raised from seed will not be the same cultivar.

Pests & Cautions

Do not use fungicides on Pinguicula; they can kill the plants. Fungus gnat larvae eat the leaves, so a thin layer of coarse sand on the soil surface helps.

About Pinguicula 'Weser'

Pinguicula 'Weser' is a butterwort selected from the same P. moranensis x P. ehlersiae cross as 'Sethos', distinguished by a white-striped lower lip and darker veining. An easy, long-lived perennial for beginners.

7 things to know before growing Pinguicula 'Weser'

1. 1Give it bright, indirect light

   Avoid strong direct summer sun, especially harsh west-facing afternoon light; a spot with filtered light through a sheer curtain works well indoors. Outdoors, some shade cloth helps soften the intensity.

2. 2Keep it moist with tray watering

   The basic method is to sit the pot in a saucer of water (tray or bottom watering) so the soil never dries out. This plant doesn't tolerate drying out well, so keep water available consistently, especially during active growth.

3. 3Use a lean, well-draining mix

   It prefers a mix with good moisture retention but low nutrient content, such as peat moss blended with sand and perlite. A ready-made carnivorous plant potting mix works well too.

4. 4Repot During Winter Rest

   Repotting periodically prevents the mix from breaking down and the roots from crowding, keeping the plant healthy. Repotting and division are best done during the winter rest period.

5. 5It forms succulent leaves in winter

   In autumn, the sticky summer leaves give way to a smooth, succulent winter rosette that no longer traps insects. Water more sparingly during this dormant phase to keep the plant on the drier side.

6. 6What to look for in a healthy plant

   Choose a plant with firm, undamaged leaves free of discoloration. A well-formed rosette center with active new growth is a good sign it will continue growing steadily.

7. 7Propagate by leaf cuttings or division

   Leaf cuttings are the easiest method: simply lay a healthy leaf on top of moist soil and it will root and grow into a new plant. Once offsets form, you can also divide the plant to increase your stock.

Frequently asked questions about Pinguicula 'Weser'

Q.Is Pinguicula 'Weser' suitable for beginners?

A.Yes, it's generally considered an easy variety for beginners. Once you get the basics of tray watering and placement right, it's manageable even if this is your first carnivorous plant.

Q.How can I tell it apart from 'Sethos'?

A.The flower shape is very similar to 'Sethos', but look for a single white stripe running down the center of the lower lip and noticeably darker, more pronounced veining — those are the key differences.

Q.Do I need to feed it insects myself?

A.No special feeding is required. The sticky leaves naturally catch small insects even indoors, so normal care is enough for healthy growth.

Q.The leaves stopped being sticky in winter — is it dying?

A.No, it's not dying. Butterworts like this one naturally shift to a smooth, succulent winter rosette in autumn and winter, which is a normal seasonal change rather than a sign of decline.

Q.How large does it eventually grow?

A.There isn't much detailed data available on its mature size, so no clear benchmark exists. Growth can vary by plant and conditions, so it's best to observe your own specimen as it develops.
