Understanding Plant Options
Nature Hills offers plants in two main formats:
- Container Plants: Grown in pots with soil, sized by container volume and plant age
- Bare Root Plants: Dormant plants without soil, sized by height measurements
Container Plant Sizes
Container sizes indicate plant age and growing capacity rather than liquid volume equivalents. Our containers follow industry-standard nursery "trade gallon" specifications, which differ from standard liquid gallon measurements.

The magnificent Kelvin Floodlight Dahlia (Dahlia 'Kelvin Floodlight') is the winner of multiple awards including the prestigious Award of Garden Merit from the Royal Horticultural Society! Dahlias thrive in hot weather, but these gorgeous sunny yellow flowers always look cool and elegant. Use them as cut flowers for fabulous vase arrangements!
This gorgeous plant has huge, bright, sunny yellow blossoms that stand atop slender stems above the ruffled, toothy, and glossy green foliage of these amazing plants. The double flowers of Kelvin Floodlight are 10-12 inches wide! Talk about butterfly landing pads! They are broad, flat-tipped petals that are sometimes wavy and a delight to see in the garden. These are not top-heavy and remain upright and straight, even when it rains.
These plants will bloom magnificently all summer through September and October when few other plants do. This Dinnerplate Dahlia is a member of the Decorative Dahlias line of flowering bulbs and can be perennial in zones 9-10. Northern growers can still enjoy Dahlia as annual accents that require being lifted in the fall before a hard frost and stored for the winter.
Planting and Application:
Dahlia are glorious blooms for cut flower gardens and pollinator beds! They make a huge impression on your perennial and cottage borders where they don't take up much room but are sure to create quite the spectacle anywhere you choose to use them! The tubers are easily brought in and stored for planting next spring or used as annual accents!
Kelvin Floodlight acts like a beacon in container gardens and planters! Drop these magnificent focal points to your Creeping Jenny spillers and other bright yellow blooming fillers! Mix among your Rose gardens for golden accents and as the next layer to your bulb gardens to shine after they've bloomed and receded in the summer heat!

#ProPlantTips for Care:
Dahlia are so easy to grow in full sun and partial shade, and in well-drained soil. Soil temperature at planting should be 60 degrees Fahrenheit. Feed monthly with a bloom-boosting fertilizer (15-30-15). Do not water until new growth appears above the ground. Once the plants are established, a deep watering twice a week will get them through the dry summer periods. Oftentimes called bulbs, but the roots of this plant are actually tubers - like potatoes, and sprout from their "eyes" and have shallow roots.
The foliage will fade in the fall and wilt with colder nights. In very cold climates, to save your tubers for the next year, dig up the plants after the first frost. Let them dry out, and then place in paper bags or boxes in a cool place. Throughout the winter, sprinkle a little water if the tubers are drying up. If you live in a warmer frost-free climate, just trim out stems to keep your plants looking their best; fresh growth will appear in the spring.
