Annual flower seeds

All our flower seeds produce flowers that are suitable for use as cut flowers. They are also used by professional nurseries and floriculture companies. For flower seeds to be considered high-quality, they need to have outstanding germination capacity and energy and therefore yield a high percentage of flowering plants. All seeds are annuals, which means that they have a lot of growing power: they go through all the stages – from a seed to a flowering plant that, in turn, produces new seeds – in the space of just one season. Most flowers bloom for about three to five months. A rule of thumb in this is that the more flowers you pick, the faster they will grow back! All our seeds are untreated and uncoated, and are also suitable as starting material for growing organic flowers.


How many seeds per m2?

Each bag contains enough for about 1 square metre of flowers, this differs per variety. Often there are more seeds so do not sow the whole bag at once. Divide the sowing over about 3 times. This way you extend the flowering season and if you fail, you can try again. Basically, a complete plant grows from a single seed so give the seeds enough space to grow into a mature plant!


How many hours of sunshine do annuals need?

The most ideal for annuals is full sun, or more than 6 hours of summer sun a day, preferably more than 8 hours. The less sun they get, the less speedy and abundant they will flower.


Planting instructions:

Plant in moist soil to which the seeds stick for best germination.

Cover the seeds with a thin layer of soil of approx. 0.5 cm.

Grow in fertile, well-drained soil.

Give them a sunny spot and sufficient protection from strong winds. Support if necessary.

Water regularly.
