Flowers are a great signifier of the beginning of Spring. In a rocky garden, planting flowering bulbs can brighten up dull areas with bursting colors. Varieties of dwarf bulbs can be spread on the ground or even placed between rocks and stones to accentuate landscapes. Naturalizing bulbs are ideal for rock gardens, as they will keep spreading and flowering again for years.
The advantage of planting naturalizing bulbs is that they inherently multiply and spread across the ground gradually. In time, they can spread in larger numbers and random patterns, known as drifts. Flowers can grow in little groups, or spaced out further apart. During planting time, you can aid this process by planting the bulbs in random spots and odd numbers, so that they bloom with a natural looking pattern.
Glory of the Snow
Chionodoxa Luciliae is one of the first flowers to bloom when spring comes. More commonly known as Glory of the Snow, these gorgeous little star shaped flowers grow low and look great bunched together. Named after their tendency to bloom while there is still snow on the ground, these flowers are endemic in the Mediterranean and native to Western Turkey. They are perennial and great at naturalizing, so they will keep coming back to grace your rock garden every year in spring. Go for their dominant blue and white colors, or choose them in shades of pink and purple.

Where To Plant Flower Bulbs In Rock Gardens
You can tuck dwarf bulbs in between rock formations or plant them around existing perennial plants. For larger areas and carpets, spread them across the ground and under trees.
Flower Bulbs and Ground Covers
A common feature in rock gardens, ground covers are a great combination with flowering bulbs to create a pleasant aesthetic garden all year round. Depending on your ground cover, choose bulbs that will grow to flower above it so they can stand out for the best effect.
Choose low growing perennial ground covers so that your bulbs can grow through with ease.
Can flower bulbs be planted after ground cover is established?
You can still add flowering bulbs to your existing ground cover. With the right tools and a little care, you can plant your bulbs between stems, making sure you dig away from the roots of your ground cover plants.
Flower Bulbs and Trees
Trees provide an excellent spot for spring flowering bulbs, especially for naturalizing. In rock gardens, this is a great space to grow bright and colorful flower beds.
Flower Bulbs and Rocks
Planting bulbs between and around rocks is a fantastic way to create a natural looking garden, as you would be mimicking the patterns of wilderness itself. Plant bulbs grouped together by variety or similarity.
Best soil for flower bulbs in the rock garden
Most importantly, use well draining soil to prevent rot from destroying your bulbs. Moreover, soil rich in humus will aid the bulbs to thrive and perform to their best abilities.
Will a flower bulb grow planted upside down?
Most of the time, bulbs planted upside down will still find their way up by turning from within the ground. Still, it’s best to plant the bulbs upright from the start but if you are unsure which way that is, opt for planting them sideways.
Will flower bulbs grow through stones?
Flower bulbs will have no trouble poking through small stones, pebbles, or loose ground cover. Avoid planting them under larger stones, as that will likely cause them to flower looking damaged or prevent them from emerging over the ground altogether.
