Sustainability

We try to produce as sustainably as possible to keep our footprint small. Therefore, our letterbox boxes are made of grass paper and tomato leaf pulp is the basic component of the seed bags. The printing is either made of paper that is 30-70% recycled paper or paper that comes from agricultural waste. In addition, you have the option to plant a tree when you place an order through Regreener.

Verbena is a very popular plant and for good reason! 'Polaris' is a much smaller variant of the well-known ironhard: it grows only 40 cm high, but it is unique with flowers in all shades of purple: from lilac to almost soft blue. A very nice plant to use at the front of your border or to put in a pot.

Indoor pre-sowing
Sow indoors in late winter or early spring. Use seeding soil in a seed tray. This species germinates in the dark, so cover the seeds well. Use a cover on the sowing tray if necessary. Place in a bright spot without direct sunlight at a temperature of about 18 - 20 degrees. Germination is irregular and slow, taking between 2 - 12 weeks. Keep soil moist but not wet. After germination, remove cover and put in a cooler place. Transplant to P9 pots when the seedling is larger than 5 - 10 cm. Harden off and transplant with 60 cm spacing. Possibly top to encourage branching. If sown early the plant will flower the same year, if sown late it will flower the following year.

Direct seeding
Direct seeding is not recommended. Remove spent flowers if you don't want out-sowing.

Which is what?

The terms may be new to you, here's what they all mean:

Annual- plants that bloom one summer and then die
Biennial- plants that you sow one year, and bloom the next year (and then die)
Perennial- plants that bloom several summers
Perennial- plants that survive frost and last for years

How many hours of sunshine?

Annuals plants almost without exception grow only in full sun. That means that you preferably need more than 8 hours of summer sun in the place where you want to grow them, for example from 10 - 18 hours. 6 - 7 hours will also go a long way, but the plants will grow just a little slower.

What soil?

Unless otherwise specified, annuals want nutrient-rich soil with extra compost in the spring. Read more about it in the Seed Guide.

Storing seeds

On the package of your seeds you will find the shelf life. You can use them until the date you see on it. An opened package is best stored in an airtight box in a cool and dark place, such as a closet in the hallway. Not sure if the germination is still good? Then it's best to buy a new pack. We deliberately choose small amounts of seeds in the packs so you don't have to waste seeds. Do you have any questions about this? Call 033 - 202 43 38 or email to [email protected], and we will help you further.
