Blue Vervain Pink Spires

Although highly adaptable, Blue Vervain thrives best in full sun. Its natural habitat is wet meadows, so unlike Argentinian verbena (Verbena bonariensis), it loves moister soil. Don't be afraid to place it:

• At the edges of ponds.
• In damp flower beds.
• In prairie plantings where moisture is retained.

In shade, it will flower less and stretch towards the light, which can cause the stems to flop.

We have good news for you – Verbena hastata is fully frost-hardy in our climate conditions (it can handle temperatures down to approx. -34 °C). Unlike its relative Argentinian verbena, you do not need to dig it up or cover it intricately for the winter. It overwinters outdoors in the flower bed without any problems.

Yes, absolutely! Blue Vervain is literally a magnet for insects. Its tiny tubular flowers are full of nectar and pollen. In the garden, it will attract:

• Honey bees and solitary bees
• Bumblebees
• Butterflies (tortoiseshells, swallowtails)

It is an ideal plant for gardens focused on supporting biodiversity.

This plant is also called "Blue Vervain" or "Swamp Verbena" in English, which suggests that it likes water. After planting, keep the soil slightly moist until the plant roots. Mature plants can tolerate short-term drought, but they will be most beautiful in soil that does not dry out completely. If you are growing the 'Pink Spires' cultivar in a drier location, give it regular watering during hot summer days.

We perform pruning in two stages:

1. Summer pruning (optional): If you want to extend the flowering period, remove spent inflorescences during the summer. This will encourage the formation of new buds.
2. Spring pruning (main): Leave the dry above-ground parts of the plant in the flower bed over the winter (they protect the roots and provide shelter for insects). Cut them back early in the spring, low above the ground, before new shoots begin to sprout.

The 'Pink Spires' cultivar is a robust plant that usually grows to a height of 100 to 120 cm. It stands out with a firm, upright habit and candelabra-like branching. Thanks to its sturdy stems, it usually does not need support if it grows in full sun. Lodging may only occur if the plant is in the shade or in over-fertilized soil with an excess of nitrogen.

Verbena is not extremely demanding on nutrients. Too much fertilizer (especially nitrogen) can lead to lush leaf growth at the expense of flowers and to stem flopping. We recommend:

• Adding a layer of mature compost to the plant in the spring.
• No further fertilization is necessary during the season if you have ordinary garden soil.

Definitely! Blue Vervain inflorescences are very decorative and last quite a long time in a vase. You can cut them:

• Fresh: In full bloom as a light, airy addition to bouquets.
• For dry arrangements: The spent seed heads have an interesting structure and can be dried.

Blue Vervain is classified as a short-lived perennial. This means that the mother plant may die after 2–4 years. However, the plant has an excellent survival strategy:

• Self-seeding: If you leave spent inflorescences on the plant in the autumn, it will shed seeds into the surroundings. In the spring, you will then find new, strong seedlings nearby that will replace the old plant.
• Thanks to this, it remains in the garden permanently, even though individual plants are renewed.

Verbena hastata is not considered toxic to dogs, cats, or horses. On the contrary, historically it has a long tradition in folk medicine (e.g., among Native Americans). Although it is not primarily poisonous, it is an ornamental plant and is not intended for common consumption like vegetables. Ingesting a large amount of plant material may cause stomach upset in sensitive individuals.

You can plant Verbena hastata seedlings in the spring after the last frosts have passed (usually mid-May) or at the beginning of autumn. Proceed as follows:

1. Preparation: Thoroughly water the plant in the pot.
2. Planting: Dig a hole slightly larger than the root ball. You can add a little compost to the bottom.
3. Watering: Water the plant generously after planting.

If you are planting a plant that was forced in a greenhouse, do not forget to harden it off (take it outside for a few hours) before planting it out, so it does not suffer shock from the sun and wind.

Blue Vervain is generally a very healthy plant. However, problems may occasionally occur:

• Powdery mildew (white coating on leaves): Appears if the plant is too dry or has poor air circulation. Prevention is sufficient watering and airy planting.
• Aphids: Can attack young shoots, but in a natural garden, predators (ladybugs, lacewings) usually deal with them.

They are often confused, but the differences are fundamental:

• Hardiness: V. hastata ('Pink Spires') is a fully hardy perennial, while V. bonariensis often freezes here.
• Water requirements: V. hastata loves moisture, V. bonariensis tolerates drought better.
• Flower: V. hastata has inflorescences arranged in pointed spikes (resembling a candelabra or spear), while V. bonariensis has flowers more in flat umbels.

Thanks to its vertical growth and soft pink color, 'Pink Spires' is perfectly suited for prairie and natural plantings. It looks excellent in combination with:

• Grasses: Miscanthus (Miscanthus), Switchgrass (Panicum), Moor grass (Molinia).
• Perennials: Coneflowers (Echinacea), Sneezeweed (Helenium), Joe-Pye weed (Eupatorium), or Burnet (Sanguisorba).

Combine it with plants that have similar moisture requirements.

Yes, it is possible, but you must take its height into account. Use a sufficiently large and heavy pot (so it does not tip over in the wind). It is important to watch the watering – the substrate in the container must never dry out completely, otherwise the plant will wilt quickly and may get powdery mildew. For growing in containers, it is more suitable to choose lower species of verbenas, but with care, this one can handle it too.
