Top 5 golden flower bulb/perennials combinations
We can't say it often enough. Naturalising bulbs and evergreen perennials make the perfect combination. Naturalising bulbs are flower bulbs that we leave in the ground. They bloom each year starting in the early spring. While we wait, the evergreen perennials provide some greenery in our outdoor spaces during the winter. Click here to view our Top 5 winning flower bulb/perennials combinations:
1. Alliums & ornamental grasses
Tall alliums with tall ornamental grasses. Alliums are available in different colours — light purple, dark purple, white and blue. Alternatively, get a mix of different allium colours so you don't have to choose. We plant the bulbs around the ornamental grasses at a depth of 15 cm, with 15 cm between each bulb. The allium bulb "Globemaster" is a real giant that we plant at a depth of 60 cm, with 60 cm between each bulb, in half or full sun. They will start to bloom in mid-spring. Even the seed heads of the Allium look nice after they have finished blooming. What's more, the flowers will come back again next year.
2. Daffodils & ornamental grasses
A winning combination of different heights and colours. The golden yellow of the tiny daffodils along with the brown or green of the taller ornamental grasses. The daffodils begin to bloom in early spring. We are especially proud of our daffodils. They won the Kassa test for the best daffodil bulbs. According to the Dutch independent test, our daffodils have the richest and most beautiful flowers. Our mixed bag of daffodil bulbs contains a true mix, meaning that three or more different types of daffodils will bloom in different colours. We plant the bulbs approximately 45 cm apart, at a depth of 45 cm, in half or full sun. We then leave the naturalising bulbs to sit comfortably in the ground so that we will see them again next year.
3. Alliums & Geranium himalayense
Alliums again? Of course. Growing to a height of 65 cm, the alliums reach high above the evergreen Geranium himalayense, which grows to 30 cm. The leaves of the Geranium turn beautiful autumn colours towards the end of the year. By the time we reach mid-spring, the tall stems and large flowers of the allium will be on show. The flowers of the geranium also start to bloom, with both plants attracting bees and butterflies — we cannot wait!
4. Crown imperial & lavender
Imperial crown and lavender — a royal combination of two tall sun worshippers. Crown imperial (Fritillaria imperialis) is a special naturalising bulb that grows giant stems with hanging "crowns". They can sometimes grow to a height of up to 120 cm. Crowns imperials start to bloom in spring, while lavender flowers a little later, so they alternate in their beauty. We plant the crown imperials 60 cm apart, at a depth of 60 cm, in full sun. This naturalising bulb will return every year.
5. Autumn crocus & Camellia japonica
Last but not least are two very special plants. Although they do not flower at the same time of year, we think they are a great combination. The autumn crocus (Colchicum autumnale) is unique as it flowers in autumn, while the evergreen Camellia japonica blooms in early spring, displaying white flowers with a yellow heart. First of all, we let the autumn crocus flower indoors. We place the bulb on the windowsill without water or soil, and the autumn crocus will bloom of its own accord. After they have flowered, we plant the naturalising bulbs outside in the earth, 50 cm apart, at a depth of 50 cm, in half or full sun. The flowers will come back each year, each time even more beautiful than before.
One downside: The autumn crocus is poisonous, so we grow them to look at only.
When do we plant flower bulbs?
We plant spring-flowering bulbs in the autumn, when the temperature is lower, as bulbs need a cold period. This allows the roots of the bulbs to properly develop. We plant them in the ground before the first frost, simply because we cannot dig in frozen earth. Freezing conditions have no effect on bulbs in the ground. We protect bulbs in flower pots using bubble wrap.
How do we plant flower bulbs?
It's very easy. We keep to the following rule: We plant the bulbs so that there is 3x the circumference of the bulb between each plant. The same applies for the depth of the hole, so that the hole is 3x as deep as the height of the bulb. In flower pots, the distance between plants is reduced so that they are planted the size of one bulb apart. As a result of this, the flowers are closer together and more compact. However, we still plant the bulbs at the same depth.
Flower bulbs and perennials in flower pots
We also plant these combinations in flower pots that we place on the patio, roof terrace or balcony, or to welcome visitors at the front door. It's important to make sure that the flower pots we use for this are large enough.
Planting flower bulbs in public spaces
We love these kinds of environments too. To add some flowers to these spaces, we plant naturalising bulbs between the perennials in public spaces so that everyone can enjoy them. Please note: Check that you are not picking a spot that is already full of flower bulbs.
